slanted lines and staggered floors create alternative spaces inside tokyo's diagonal house

HAMS and Studio undertook the renovation of an apartment situated in the suburbs of Tokyo, Japan, with the intention of transforming it into a flexible living environment tailored for a working couple. The project, titled 'One Nuance,' aimed to deviate from the apartment's original rigid grid plan by introducing subtle variations in spatial composition, color, and material finishes. This strategic approach sought to create an adaptable living space that could accommodate a diverse range of activities and lifestyles. The design process commenced by addressing the existing layout, which notably featured a corner-room configuration. The primary intervention involved the elimination of traditional corridors, a common feature in many apartments that can fragment spaces and limit natural light. In their place, smaller, more versatile rooms were arranged along the exterior walls. This reorientation served to maximize natural light penetration and foster a brighter, more open ambiance throughout the apartment, significantly enhancing the overall sense of spaciousness. A central element of the redesigned apartment is the living room, conceived as an open and fluid zone. This open-plan living area establishes direct connections with the surrounding smaller rooms, promoting an interactive and relaxed atmosphere. A distinctive feature of the renovation is the implementation of a 'double-opening' design. This innovative system comprises 'outer openings' that are strategically positioned to draw natural light deeper into the interior spaces. Complementing these, 'inner openings' are integrated into the internal partitions, serving to frame and visually connect various living activities happening within the apartment, thereby creating a continuous and expansive internal vista. The aesthetic and functional versatility of the apartment is further elaborated through the nuanced design of the internal facades. The appearance of these facades is intentionally varied, contingent upon the specific purpose of each adjoining smaller room and the type of partition employed. This thoughtful differentiation generates a series of unique 'viewports' throughout the home, adding visual interest and spatial depth. For instance, robust plastering was selected for the internal walls, providing a textured and durable surface. In contrast, glossy solid finishes were applied to the passages leading to the living room, contributing to a sense of fluidity and light reflection. The selection of materials and finishes, characterized by subtle textures and a cohesive color palette, was critical in establishing the apartment's dynamic and harmonious environment. The objective was to ensure that while individual spaces retained their distinct character, they collectively formed a unified and aesthetically pleasing whole. This attention to detail in material application and color scheme reinforces the project's 'One Nuance' concept, where slight variations contribute to a richer and more adaptable living experience for the inhabitants. The renovation successfully transforms a standard suburban apartment into a sophisticated and highly functional dwelling, ready to meet the evolving needs of its occupants. #ApartmentRenovation #TokyoArchitecture #FlexibleLiving #InteriorDesign #SpatialComposition #HAMSandStudio #ResidentialArchitecture #OpenPlanLiving

The "Diagonal House" is a residential project designed by Daisuke Ibano and Ryosuke Fujii for a family with children, situated in a densely populated urban area of Japan. The design process began with addressing the site's unique characteristics, specifically the height restrictions imposed by local regulations. A portion of the lot fell within a Category 1 height control district, necessitating careful consideration of the building's form and orientation to comply with setback requirements and integrate into the existing townscape. The architects approached this challenge by conceptualizing the diagonal lines inherent in the setback regulations not as limitations, but as opportunities to define the building's overall structure and create a distinctive architectural expression. This approach led to the development of a design that actively incorporates these diagonal elements, moving beyond a simple adherence to legal constraints. The diagonal lines serve multiple functions: they shape the exterior facade, influence the internal layout, and contribute to the house's unique spatial experience. A key aspect of the design involves the strategic use of these diagonal lines to introduce an element of distortion and dynamism into the interior spaces. This creates a sense of depth and visual interest, diverging from conventional rectilinear room arrangements. The internal planning also utilizes split-level flooring, further enhancing the spatial complexity and encouraging a fluid movement between different areas of the home. This multi-level approach, combined with the diagonal forms, allows for varied perspectives and interactions within the house, optimizing the use of the 104 square meter area. Furthermore, the diagonal planes are instrumental in filtering light and views. By carefully angling and positioning windows and openings along these diagonal lines, the architects control the ingress of natural light, ensuring adequate illumination throughout the day while maintaining privacy from neighboring properties. This thoughtful integration of light and views enhances the living environment, creating a bright and airy atmosphere despite the urban density. The material palette for the house primarily features concrete, which contributes to the contemporary aesthetic and structural integrity of the design, complementing the angular forms. The project ultimately represents an innovative response to stringent urban planning regulations, transforming potential constraints into defining architectural features. The resulting "Diagonal House" not only meets the practical needs of its inhabitants but also offers a visually stimulating and functionally optimized living space that stands out within its urban context. The design demonstrates how a deep understanding and creative interpretation of architectural guidelines can lead to original and impactful residential architecture. #ResidentialArchitecture #HouseDesign #UrbanPlanning #DiagonalDesign #JapaneseArchitecture #SplitLevel #ConcreteConstruction #SpaceOptimization #ArchitecturalInnovation

Yuji Kimura Design has completed House K, a three-storey residential project located in a busy Tokyo neighborhood. The primary design challenge was to reconcile the client's desire for private outdoor terraces with the need for privacy on a street with significant traffic. To achieve this, the architects implemented a design strategy that involves a tall, white perimeter wall effectively shielding the house and its outdoor spaces from public view. The house is conceived as an elongated box extending from east to west, a configuration that optimizes natural light exposure. The southern facade incorporates the bedrooms and terraces, strategically positioned to receive ample sunlight throughout the day. To further enhance privacy on these terraces while still allowing light and air, slatted timber and translucent panels are used as screening elements, preventing direct views from passersby. In contrast, the northern facade features smaller, horizontal slit windows. These openings are designed to bring natural light into specific areas such as the ground-floor living room and toilet, and the first-floor bathroom and hallway, without compromising the overall sense of seclusion. Upon entering House K, residents are greeted by a functional and uncluttered entrance hall on the ground floor. This space integrates full-height cabinets with recessed handles, creating a streamlined appearance and maximizing storage efficiency. The entrance hall transitions into an open-plan living area, which includes a kitchen, dining room, and a study area. A notable design detail in the ground-floor toilet is the full-height door, which, when closed, blends seamlessly with the wall, contributing to the minimalist aesthetic. Connecting the different levels of the house is a steel staircase with open timber treads. This design choice is not merely aesthetic; it also facilitates the flow of natural light between the upper and lower floors, enhancing the brightness of the interior. The staircase extends upwards to a loft space, further contributing to the natural illumination within the dwelling. The first floor is dedicated to private quarters, housing three bedrooms along one side and a bathroom and separate toilet on the other. Consistent with the ground floor, the doors to these private rooms are also full-height, maintaining a cohesive and less obtrusive visual language when closed. Throughout the interior, Yuji Kimura Design has maintained a minimalist material palette, predominantly featuring white walls and light timber floors, which contributes to a bright, spacious, and serene atmosphere. The total area of the house is 95.98 square meters, built on a site of 120.1 square meters, with a building area of 47.99 square meters. #TokyoArchitecture #JapaneseHouses #PrivacyDesign #ModernResidential #WhiteFacade #TerraceDesign #MinimalistInterior #YujiKimuraDesign

The Tokyo-based architecture firm matsuokasatoshitamurayuki, led by Satoshi Matsuoka and Yuki Tamura, has completed a courtyard house in a commuter town near Tokyo. This residential project features a distinctive pleated radial floor plan and integrates a small garden and outdoor living spaces around its perimeter. The design aims to strike a balance between interior privacy and connection to the surrounding environment, drawing inspiration from traditional Japanese house designs, particularly the 'geya' architectural element. The design strategy involved lowering a small roof attached to the main house to align with the site's borders, following the natural contours of a berm. This approach, combined with the pleated plan, creates varied depths within the structure. The architects aimed to preserve the appearance of the area's characteristic 'geya' house design while fostering the community culture associated with small gardens and berms. The pleated internal spaces are designed with initial specific functions but are intended to adapt to evolving uses over time. The house is configured to accommodate two families within a limited floor space, meaning individual rooms are not designed to be self-sufficient but rather part of a larger interconnected whole. Key interior elements, such as counters and tables, are positioned to extend beyond their designated areas, promoting a fluid transition between spaces. Abundant natural sunlight is a central feature, filtering through windows to illuminate every corner of the home. The 'geya' section, located beneath the small roof, provides a comfortable, sunlit area near a window, suitable for family gatherings or individual relaxation. This space is envisioned to be versatile, functioning as a communal hub while also allowing for separate activities. A central room, measuring 4.5 x 5.5 meters with a ceiling height of 4 meters, forms the core of the house. This area offers a private, bright space for the family, flexible enough to adapt to future needs and changes. The design consciously integrates the concept of a courtyard house, where internal spaces are protected while maintaining a connection to the outside. Unlike typical courtyard houses that are often closed off from the exterior, this residence opens sensitively towards the surrounding berm, ensuring privacy for the residents while remaining approachable to neighbors. The architects describe it as a "closed home" that allows the family to live in peace. The exterior of the main house features a tower-like central room, which serves as a symbolic icon for the family. By adopting and adapting the characteristic appearance of vernacular homes in the area, the architects hope the house will become an enduring and integrated part of the local community. The project details include a wooden structure, with wood and steel as major materials. The site area is 166.58 square meters, with a building area of 82.40 square meters and a total floor area of 101.72 square meters. The structural consultant was ASA – Akira Suzuki, and the general contractor was Yasumatsu Tekken. #Architecture #ResidentialDesign #CourtyardHouse #PleatedFloorPlan #JapaneseArchitecture #Tokyo #GeyaConcept #FamilyHome #ArchitecturalInnovation

Kiri Architects has designed a compact family home in Nishitōkyō, an area west of Tokyo's city centre, known as Light-Filled Stair Hall. This 79-square-meter residence is shortlisted in the Urban House category of Dezeen Awards 2022. The design centers around a significantly expanded stairwell that occupies approximately one-third of the total living space, transforming it from a mere transitional element into a versatile social hub for the family of four. Inspired by the *engawa*, a traditional Japanese veranda, principal Keisuke Kiri envisioned the staircase as a dynamic space capable of various functions beyond simple circulation. The stairwell stretches across the entire width of the house, positioned directly behind a full-height glazed facade. This strategic placement allows ample daylight to permeate the interior while simultaneously providing a visual buffer that offers privacy from neighboring properties, a crucial consideration in densely populated Tokyo where land parcels are often small. Constructed with a minimalist approach, the staircase features 50-millimeter-thick wooden treads and risers supported by a system of timber columns and suspended steel rods. This open structure not only maximizes light penetration but also integrates the staircase seamlessly into the living environment. The wide stair treads are designed to be comfortable for sitting and relaxing, and the handrail can even serve as an extended washing line on sunny days, highlighting its multifunctional intent. The ground floor of the house features an open-plan layout intelligently divided by a stepped floor level. One section accommodates a kitchen and dining area with a large island counter, while the other functions as a lounge, complete with a family piano. A wall of integrated storage, including a pantry, flanks this area. Upstairs, a family bathroom is located adjacent to a spacious bedroom. This bedroom is fronted by six glazed doors, which provide flexibility for future subdivision of the space as the children grow, allowing for adaptability in room configuration. An additional feature is a small work-from-home area, thoughtfully incorporated with shelving and a desk at the end of the first-floor landing of the stairwell. Light-Filled Stair Hall is recognized for its innovative use of space and its response to the challenges of urban living, making it a contender for the Urban House of the Year at the Dezeen Awards. The project demonstrates how architectural elements, traditionally seen as functional, can be reimagined to enhance social interaction and adaptability within a compact urban dwelling. #JapaneseArchitecture #ResidentialArchitecture #TokyoHouses #StaircaseDesign #CompactLiving #UrbanHouse #DezeenAwards #KiriArchitects

The Byoubugaura house, designed by Japanese firm Takeshi Hosaka Architects, presents a distinctive approach to residential architecture, camouflaging its unique interactive spaces within a seemingly conventional concrete box and glass facade. The exterior maintains a regular appearance, yet a closer inspection reveals a complex internal structure that challenges traditional spatial perceptions. The residence is structured with a basement level and two floors above ground. The architectural design is characterized by its innovative use of concrete floor plates, which are dramatically curved upwards at both the front and rear facades. This curvature serves a dual purpose: it strategically obstructs direct views into the living areas, enhancing privacy from neighboring structures, and simultaneously creates a unique visual effect where the interior spaces appear sunken below the established structural grid. A key design element is the blurring of spatial distinctions between the different levels. Despite being on separate floors, the curved concrete plates create an illusion of uniformity, making each level feel interconnected and spatially ambiguous. This design choice contributes to an unexpected sense of depth and enclosure within the home. The integration of wooden floors throughout the interior complements the concrete structure by providing warmth and reflecting the indirect natural light that filters into the spaces. This strategic use of materials ensures the home remains livable and inviting, despite its unconventional concrete forms. Further enhancing the home's interactive quality are the four large glass panes on each level. These panels are designed to slide back and forth, offering various open-air configurations and allowing residents to control the flow of natural light and ventilation. This flexibility transforms the living spaces, adapting them to different moods and environmental conditions. A circular staircase, an integral part of the design, slices through the curved floor plate, connecting the levels. This architectural feature not only provides vertical circulation but also exposes a small section of the floor's construction, offering a glimpse into the building's structural ingenuity. The project details highlight the meticulous planning and execution behind Byoubugaura. The structural engineering was handled by Kenji Nawa, with photography by Koji Fujii / Nacasa&Partners Inc. The client for this innovative residence was Toshiyuki Kondo. Located in Yokohama, Japan, the house is constructed from reinforced concrete. It occupies a site area of 65.16 square meters, with a building area of 30.28 square meters, and a total floor area of 90.84 square meters, distributed across the basement, first, and second floors. The building stands at a height of 5494 mm, comprising a basement, first floor, and second floor. The design phase spanned from March 2011 to September 2011, with construction commencing in September 2011 and reaching completion in the spring of 2012. This project exemplifies an architectural exploration of material properties and spatial dynamics, creating a home that is both aesthetically striking and functionally adaptable. #ArchitecturalInnovation #ConcreteDesign #JapaneseArchitecture #ResidentialArchitecture #TakeshiHosakaArchitects #InteriorDesign #SlidingGlassPanels #SpatialBlurring #ModernHome

Tato Architects, led by founder Yo Shimada, undertook the renovation of an 87-square-metre traditional Japanese house in Hyogo Prefecture for a young couple. The original structure, a single-storey residence, featured a layout comprising six main rooms, a configuration deemed unsuitable for the clients' modern lifestyle. The renovation aimed to transform the segmented interior into a more open and adaptable living space. The core of the renovation involved completely stripping the interior to expose the existing wooden structural framework. Instead of re-establishing traditional partitions, Shimada introduced a novel approach using two curving lengths of plywood to define different functional zones. This design choice was influenced by an earlier experimental project by Tato Architects in 2013, which involved a public toilet building on Shodoshima Island where curved walls were used to divide space. While that project focused on a new build, Shimada believed the concept held greater potential when applied to the renovation of an older structure, allowing for a blend of historical context with modern spatial dynamics. The plywood screens were strategically placed within the house. One screen was installed along the north-eastern side, creating a private area that encloses a bedroom and an adjoining closet. The second screen was positioned towards the back of the house, wrapping around a bathroom and a guest bedroom. This curvilinear partitioning system allowed for a fluid transition between areas, contrasting with the rigid divisions of the original layout. The front portion of the building was specifically designed to be more open plan, maximizing natural light and offering direct access to a newly designed narrow garden. Budgetary constraints influenced the material selection for the curved walls. Initially, 20-millimetre-thick plywood was considered, but it proved to be too flimsy for the desired structural integrity and aesthetic. To overcome this, a solution was devised where a framework of steel rods was sandwiched between layers of plywood, providing the necessary stability while maintaining the curved form. This simple yet effective modification allowed the architects to achieve their design vision without exceeding the project's financial limits. The redesign also incorporated new flooring throughout the living areas, featuring a mortar floor with integrated underfloor heating for enhanced comfort. The bathroom was finished with polycarbonate plastic, offering a clean and modern aesthetic. A small loft space was added above the main bedroom, accessible via a ladder, providing additional utility. For the exterior of the house, a new cladding of charred cedar boards was chosen, contributing to a refreshed facade while respecting traditional Japanese architectural elements. #TatoArchitects #Hyogo #Japan #ResidentialArchitecture #HouseRenovation #JapaneseHouses #PlywoodInterior #CurvedWalls #ModernRenovation

Giselle Go and Philippe Terrien, co-founders of the Japanese clean beauty brand DamDam, embarked on a search for a tranquil weekend retreat near Tokyo. Their initial criteria included proximity to the city, high privacy, and a mountainside location. After a prolonged search, a friend, Naoko Kawamura, introduced them to a 75-year-old property overlooking the Pacific Ocean and Mount Fuji. The house, initially dilapidated, held historical significance as it was built by American postwar photojournalist Horace Bristol, known for his work on John Steinbeck’s 'Grapes of Wrath' and for magazines like 'Life,' 'Time,' and 'National Geographic' in the 1950s. Recognizing the challenges of renovating such an old property, especially one situated on protected heritage land, the couple enlisted the expertise of Motosuke Mandai of Mandai Architects. Their vision was to revive the house while preserving its past and integrating modern comforts. A significant part of the renovation involved working closely with the local temple that oversees the protected area to ensure all regulations were met. The couple meticulously retained original elements like wood beams, ceilings, and shoji screens. When original features such as the wood floors or the wood-burning stove could not be salvaged, they were replaced with identical materials to maintain the house's authentic character. The entrance to the home functions as both an entryway and a mudroom, where it is customary to remove shoes and don soft house slippers, a Japanese tradition. This space features a Hang-It-All coatrack by Eames for Herman Miller, a stool by Timber Crew, and a washi tray by Craig Ancelowitz, both for DamDam Atelier. Artwork includes a calligraphy on canvas by Mikiko Kayama and a wall sculpture by Yuichiro Kobayashi. The living room, a favorite indoor spot for the couple, boasts an Akari 21A pendant light by Isamu Noguchi, an Archimoon Soft table lamp by Philippe Starck for Flos, and Glo-ball table and floor lamps by Jasper Morrison for Flos. The sofa is an N701 modular model from Ethnicraft, complemented by an Airframe coffee table by David Chipperfield for Cassina. This room offers direct views of the sunset over the sea, with garden-facing windows framing the sofa, and features a wood-burning stove for winter warmth. The dining room serves as a dual-purpose workspace. Original shoji screens provide privacy from the north-side bamboo, while the room opens to sea views on the west. This area includes a Flowerpot Verner Panton 1968 pendant light from &Tradition, Series 7 dining chairs by Arne Jacobsen for Fritz Hansen, and an Airframe dining table by David Chipperfield for Cassina, which was restored with a new walnut-wood top by Timber Crew. Custom shelving by Douguya and an Akari 3x table lamp by Isamu Noguchi further personalize the space, along with washi artwork and a painting by Philippe’s son, James. The kitchen, a beloved space for Philippe, was enlarged by removing an old bathroom, placing it centrally within the home with garden access. To address the lack of natural light, Motosuke Mandai incorporated floor-to-ceiling windows into the traditional ranma (wall panels), creating the illusion of a floating roof and flooding the interiors with sunlight. An engawa, a traditional Japanese hallway, was transformed into a sunroom, enlarged and opened to a seaside deck for sunset aperitifs and gardening activities. This room is furnished with an Akari 1AG table lamp by Isamu Noguchi, an antique rattan table, a vintage lounge chair, and a Malawi chair from Couleur Locale. The decor reflects the multicultural backgrounds of Giselle, who is Filipino, and Philippe, who is French, blending midcentury-modern design, vintage finds, Japanese crafts, and textiles from their travels. The furniture, much of which was crafted by artisans known to them, imbues the home with a personal touch. The only fully enclosed room is the bedroom, which offers a private sanctuary feel, without glass windows on the ranma. The bed frame is by Timber Crew, and the table lamp is the Archimoon Soft by Philippe Starck for Flos. Wood stools designed by Timber Crew for DamDam Atelier complete the room. A large ofuro (bathtub) at the end of the bathroom provides a relaxing space. The interior design blends Japanese architectural elements like sugi-finish floors and preserved pinewood ceilings with a diverse collection of furnishings, embodying an old-world travel museum aesthetic that reflects the owners’ journeys and personal connections. #JapaneseHouse #ZenHideaway #HistoricRenovation #InteriorDesign #TokyoHome #ArchitecturalDesign #MidCenturyModern #MulticulturalDecor #DamDam

KIRI architects, based in Tokyo, has designed a compact dwelling featuring a prominent, light-filled stair hall. This unique architectural element occupies one-third of the house's total volume and extends across its entire length. The design strategically positions the living areas to the north, while an open, sunny garden is situated to the south. The glazed and elongated stair hall serves a crucial function in bringing natural light and external views into the interior spaces, which might otherwise be confined and dimly lit. This central feature transforms what could be a compact and potentially dark home into an airy and inviting residence. Within the expansive stair hall, the design team at KIRI architects has incorporated various spaces intended for lingering and relaxation. These include a spacious engawa, a traditional Japanese veranda, which offers views of the garden. Additionally, a dedicated study area is positioned to provide a vista of the street. The architects emphasize the multi-functional nature of the stair hall, noting its adaptability. For instance, the handrail can be utilized as an extended clothesline on sunny days, while the stair treads are designed to be wide enough for sitting and relaxing, allowing residents to enjoy activities such as listening to music from the lower level. This zone is described as a 'sublime space filled with light and breeze,' highlighting its role as a comfortable and dynamic hub within the home. The structural integrity of the staircase is maintained by a series of slender timber columns and 16-millimeter steel rods that are suspended from the ceiling. The timber treads and risers of the stairs are securely bolted together and fastened onto a steel girder, ensuring both stability and a refined aesthetic. The architects acknowledge that, at first glance, the scale of the staircase might appear disproportionate for a dwelling of its size. However, they clarify that the light-filled stair hall is not merely a functional element for vertical circulation but also acts as a significant mediator of the surrounding environment. The slender yet overlapping columns within the stair hall subtly delineate the living spaces from the garden and neighboring properties. This arrangement allows a substantial amount of sunlight to enter the home, which is then filtered and softened by the various elements of the staircase—including the stairs themselves, the handrail, and the hanging rods. The result is a mellow and ample quality of light that permeates the living spaces beyond the central hall. In adherence to the principles of metabolism, a architectural movement that emphasizes flexibility and adaptability, the bedroom on the upper floor facing the staircase features a recurring series of folding doors. This design choice anticipates future needs, allowing for the potential division of the space into smaller children's rooms as the family evolves. Similarly, the ground floor living room is designed to open up completely to the garden, providing children with direct and unhindered access to the outdoor space. This thoughtful integration of flexible design and natural light creates a living environment that is both aesthetically pleasing and highly functional, responding to the dynamic needs of its occupants within a compact Japanese urban setting. #JapaneseArchitecture #CompactLiving #StaircaseDesign #NaturalLight #ResidentialArchitecture #FlexibleInteriors #MetabolistInfluence #ArchitecturalInnovation

This project, conceived for an architect and his family, delves into the intricate relationship between internal living areas and the surrounding urban environment. The architectural approach is heavily influenced by the Japanese concept of ‘Ma’, emphasizing the dynamic interplay of space and time. The house is meticulously designed to facilitate a smooth transition between private family zones and the more public aspects of the neighborhood. The design incorporates strategically placed apertures that serve multiple functions. These openings allow for the ingress of indirect natural light, illuminating the interior spaces with a soft, diffused glow. Concurrently, they frame carefully curated views of the adjacent neighborhood and the distant city, thereby strengthening the occupants' sensory and perceptual connection to their external environment. These visual connections also provide subtle glimpses of the family's daily life to the outside world, fostering a sense of community and enhancing human interaction with the surroundings. The KDH2 residence features an open, continuous spatial arrangement that seamlessly links the upper and lower floors. A distinctive element of the second floor is its undulating wooden ceiling, which not only draws the eye towards panoramic views of the city but also instills a feeling of stability and enclosure within the primary family activity area. Through subtle architectural cues rather than physical barriers like doors, various zones within the house are differentiated. This design choice allows family members to maintain an awareness of each other's presence through auditory cues, such as voices and ambient sounds, reinforcing a sense of togetherness within the open layout. An L-shaped floor plan is central to the home's design, ensuring that every room benefits from a direct connection to the garden. This configuration further blurs the lines between indoor and outdoor living, creating a harmonious and integrated living experience. Noesis Architecture & Design has opted for a palette of simple, enduring materials, including natural wood and stucco.

This intentional material selection contributes to the house's organic integration into its environment and its capacity to evolve aesthetically with its inhabitants. #JapaneseArchitecture #ResidentialDesign #FluidSpaces #UndulatingCeiling #IndoorOutdoorLiving #OkayamaHouse #ModernArchitecture #WoodAndStucco

A Cat Tree House, located in Kamakura, Japan, is a private dwelling and work studio designed by architect Tan Yamanouchi for himself, his partner, and their two cats. The design of the residence prioritizes the needs and behaviors of the feline inhabitants, integrating them seamlessly with human living spaces. Yamanouchi, drawing from ten years of observation, identified three primary cat needs: the ability to choose comfortable temperature levels, the desire to be in the same room as owners while maintaining personal space, and the necessity of multiple safe hiding spots. These considerations informed the core architectural concept of the home. The residence is structured around a large spiral staircase, or caracole, featuring multiple nooks and crannies. This central element includes an atrium with a skylight, allowing natural light to penetrate the interior. The staircase steps are designed with varied rises, based on the body measurements of the cats, resulting in 23 distinct floor levels. This stratification creates fine layers of temperature zones, enabling the cats to move freely and find their preferred climate throughout the day. The run of each step is generously set at 900 millimeters, providing ample space for cats to hide, maintain distance, or rest undisturbed. The caracole's design draws inspiration from a tamasudare, a traditional Japanese bamboo screen, influencing its loosely woven and adaptable structure. This exposed architectural feature also addresses Kamakura's highly humid climate, complementing the split-level design. A buffer space, one meter above ground level, is integrated between the raft foundation and the floor. This area facilitates airflow and accommodates hot water pipes for floor heating, contributing to effective temperature and humidity control within the house. Around the caracole, various functional spaces are arranged on different levels, including a bedroom, guest room, studio, kitchen, dining room, and bathroom. These rooms are designed not only for human comfort but also to serve as potential hiding places for the cats, particularly when guests are present. Fall prevention handrails in the atrium are inspired by Kamakura's mountain views and are crafted from delicate stainless steel. A bookshelf is integrated along the spiral steps, transforming the passage into a multi-level library for humans and cozy resting spots for cats. One section of the circular steps extends backward, leading to a window positioned at cat eye level, providing an outdoor view. The final step of the staircase is elevated to the height of a human chair, creating a porch-like area for the cats. The house's exterior form comprises two interlocking L-shaped volumes with shed roofs of varying angles. This configuration simplifies construction and harmonizes with the natural landscape of Kamakura. The architect also intentionally designed window placements and heights to allow passersby to observe the cats, integrating them into the architectural exterior and local scenery. In terms of landscape design, the garden is divided into two main zones: an Approach Zone leading to the entrance and front garden, and a Terrace Zone with a wooden deck and kitchen garden. The Approach Zone features approximately 80 species of plants, providing a diverse color palette, while the Terrace Zone hosts 20 species of edible herbs. An outdoor space covered with fragrant wood chips offers a place to sit and dine, completing the home's comprehensive design that caters to both human and feline occupants, harmonizing their needs within a thoughtfully constructed environment. #CatFriendlyDesign #JapaneseArchitecture #SpiralStaircase #ResidentialArchitecture #PetCenteredDesign #SustainableDesign #KamakuraHome #MultiLevelLiving #ArchitecturalInnovation

This article presents the 'House in Tama' project, designed by Cheng Hao Chung Architect, located on the border of Kanagawa and Tokyo, Japan. The house is situated on the southern slope of a hill, offering ample sunlight and a clear atmosphere, despite being in a dense residential neighborhood. The design approach for this 116 square meter residence, completed in 2024, focused on integrating with the natural topography and maximizing light and views while ensuring privacy and comfort for the inhabitants. The architectural concept emphasizes a multi-layered structure that adapts to the sloping site. The design creates a sequence of distinct yet interconnected spaces, each with its own relationship to the exterior environment. The architects utilized a combination of concrete, wood, and glass as primary materials, contributing to both the structural integrity and the aesthetic of the house. Concrete provides a robust foundation and defines the main volumes, while wood introduces warmth and texture in interior finishes. Large glass panels are strategically placed to blur the boundaries between indoor and outdoor spaces, allowing natural light to penetrate deeply into the living areas and offering framed views of the surrounding landscape and the distant Buddhist cemetery. A key aspect of the design is the careful consideration of the site's unique characteristics. The building form responds to the contours of the hill, creating a stepped profile that minimizes its visual impact and blends with the terrain. The internal layout is organized to take advantage of the southern orientation for optimal sunlight exposure and to create a comfortable microclimate within the house. The use of varied ceiling heights and spatial configurations contributes to a dynamic and engaging living experience, moving from more intimate, enclosed areas to expansive, open-plan zones that facilitate family interaction and entertaining. The project involved collaboration with structural engineer Jun Yanagimuro and constructor Sekkeikomu. The construction process highlighted attention to detail in material selection and craftsmanship, aiming for a durable and aesthetically pleasing outcome. The interior spaces feature a minimalist aesthetic, allowing the quality of materials and the interplay of light and shadow to define the atmosphere. The design includes functional elements such as a modern kitchen, comfortable living areas, and private bedrooms, all designed with a focus on usability and long-term sustainability. Overall, the House in Tama demonstrates an architectural solution that responds thoughtfully to its context, balancing modern design principles with respect for the natural and cultural landscape. The project showcases how a residential building in a challenging urban-natural interface can achieve both architectural distinction and a high quality of life for its residents through careful planning, material selection, and a strong conceptual vision. The dwelling serves as a contemporary example of Japanese residential architecture, prioritizing light, views, and a harmonious relationship with its immediate surroundings. #ResidentialArchitecture #JapaneseArchitecture #ModernDesign #SlopingSite #NaturalLight #Concrete #Wood #Glass #UrbanIntegration #SustainableDesign

The "Sunroom House in Tsukaguchi" project by FujiwaraMuro Architects is situated in a tranquil residential area, replacing the client's original family home. The architectural design strategically divides the structure into two main volumes: an LDK (living, dining, and kitchen) area and separate private rooms. A key design element is the use of split-level floors within the main living space, which serves to enhance the perception of spaciousness. This vertical segmentation also fosters improved connectivity and communication among occupants across the dining room and kitchen areas, allowing for visual and auditory interaction across different levels. The residence was completed in 2024 and spans an area of 105 square meters. The project's photography was carried out by Katsuya. Taira (studioREM). FujiwaraMuro Architects acted as the lead architects for this residential undertaking in Japan, focusing on a house typology. The design emphasizes thoughtful spatial organization to maximize both functionality and aesthetic appeal within a relatively compact footprint. The split-level approach, common in modern Japanese residential architecture, is utilized here to create dynamic interior volumes and distinct zones while maintaining an open feel. The overall design philosophy appears to prioritize a sense of openness and inter-connectivity, which is crucial in urban residential settings where space is often limited. By integrating the LDK and private rooms into a cohesive yet differentiated layout, the architects aim to support contemporary family life, providing both communal gathering areas and quiet retreats. The project reflects a careful consideration of the site's context and the client's needs, resulting in a design that is both practical and visually engaging. The selection of materials and finishes, while not explicitly detailed in the provided text, would typically align with modern Japanese architectural trends, often incorporating natural elements, minimalist aesthetics, and efficient use of light. The term "Sunroom House" in the title suggests a focus on natural light and potentially a specific area designed to capture sunlight, contributing to the dwelling's ambiance and energy efficiency, though further details on this aspect are not available in the given text. #ResidentialArchitecture #JapaneseArchitecture #SplitLevelDesign #InteriorDesign #ModernHome #FujiwaraMuroArchitects #Tsukaguchi #ArchitecturalPhotography #SpaceOptimization

FT Architects, led by Katsuya Fukushima and Hiroko Tominaga, completed a residential project in Tokyo, Japan, named "Column and Slab." This three-story house is situated on a narrow urban plot, measuring only 5 by 14 meters, and is surrounded by other properties on three sides, with only its narrow frontage open to the street. The architects' previous projects, "e-house" and "s-house," also located in densely populated areas of Tokyo, explored methods to mitigate urban density, such as using free-form, cranked screens. However, for the Column and Slab house, the approach shifted to address the oppressive feeling of tight surroundings by evoking historical dwelling forms and challenging the urban environment directly. The structural design of the house incorporates a grid frame of concrete columns and beams. Eight concrete columns, each 300mm square, are integrated within the interior, positioned on a 2.6m x 3.0m grid. These columns support two 100mm-thick raised floors, which cantilever out at the sides to maximize the building's width within the constrained site. The need for ground improvement necessitated the use of this column-and-beam system, confining groundwork to the areas beneath the columns. The architects noted that during construction, the site resembled an archaeological excavation of ancient Japanese columns, highlighting the integration of traditional structural elements. The third story of the house is constructed from timber and is described as a "timber box" sitting atop the concrete structure, akin to a penthouse. This combination of concrete and timber structures forms a simple yet logical solution to the client's desire for maximum space while adhering to urban regulations and environmental limitations. The architects emphasized the client's cooperative attitude, even joking about the rough concrete columns becoming part of the family, indicating a positive engagement with the unconventional design elements. The interior layout is designed to offer a unique spatial experience. The ground floor, referred to as the "doma" (earthen floor room), features the grid of columns delineating three distinct spaces, each approximately 4.5 tatami-mats in size, complemented by 0.95m wide aisles on either side. This "doma" concept is intended to blend the outside urban environment with the interior. The first floor has a slightly lowered ceiling height, creating a sense of both tension and intimacy. Mobile storage units and a light well loosely partition the bedrooms from the bathroom on this level. The second floor houses the main domestic hub, featuring an open, box-form space with generous openings and a relaxed atmosphere, suitable for dining. The eight concrete columns on this floor serve not only a structural purpose but also act as flexible elements, removing the need for fixed partitions and allowing the space to adapt to future changes in family life. This adaptability is seen as a crucial functional aspect of the columns, extending beyond their primary structural role. The architects aimed to create a house that, in the chaotic urban landscape of modern Tokyo, stands out like a museum. They sought to integrate traditional forms into contemporary living without being nostalgic, thereby establishing links to architectural tradition and generating spatial tension. The design merges modernist grid frames with traditional Japanese elements like columns and raised floors. This approach represents an effort to develop an architectural language that utilizes established forms in a vivid, contemporary setting, avoiding purely nostalgic or traditionalist interpretations. The house has a total floor area of 105.6m2 and is primarily made of reinforced concrete, with a partial wood structure for the third story. #FTArchitects #TokyoArchitecture #JapaneseHouses #ColumnAndSlab #NarrowLotDesign #ConcreteArchitecture #UrbanHousing #ModernistJapanese #ResidentialDesign

Architect Andrew Lister designed a distinctive home for actor Yuri Kinugawa and film producer Owen Hughes in the Auckland suburb of Waterview. The residence, characterized by its tall silhouette, narrow upper window, and a blank cedar-clad facade, adheres to the principles of the Direct Compass, a Japanese discipline akin to feng shui. The home's exterior, covered in cedar weatherboards, initially appears utilitarian, yet conceals a thoughtfully designed interior. The house's structure is composed of two primary boxes connected by a passageway and an adjoining bathroom. Despite its compact footprint, the design creates an illusion of greater spaciousness, as noted by Hughes. A prominent feature of the living room is a two-story bookcase spanning the entire northern wall, housing Hughes’ extensive book collection. This vertical storage solution ingeniously maximizes space, drawing the eye upwards and adding visual texture without encroaching on floor area. The central area of the home is laid out efficiently, with the kitchen to the left and the bedroom to the right. Above these spaces, two offices are stacked, accessible via a stairway at the rear of the room. The interior is enriched by family antiques and Japanese textiles, which introduce complementary textures, transforming the angular space into a welcoming environment. Following Direct Compass principles, the bedroom, considered vital for family relationships, overlooks a small zen garden on the south side of the house. This placement is believed to promote mental clarity due to cooler temperatures. A six-foot-long passageway clearly delineates the transition from the public kitchen and dining areas to the private bedroom. The traditional Japanese bathroom, situated off the central passageway, serves as a space for washing before bathing in a wood-lined onsen (tub). While the north side of the house offers views of an estuary, the street-facing facade maintains a minimalist, private appearance. In stark contrast, the west-facing side features a double-height glass wall that can be fully opened, merging the living space with a veranda. This outdoor area overlooks the garden, estuary, and harbor, providing a setting for observing sunsets and occasional dolphin sightings. The home's exterior features low-maintenance Canadian cedar cladding and aluminum joinery, designed to age gracefully and harmonize with the surrounding garden's sculptural desert plants. The durability of these materials is crucial, given the home's exposure to south-westerly winds laden with salt from the estuary, a condition the chosen plants tolerate well. #JapaneseDesign #BoxHome #TwoStoryBookcase #SmallSpaceLiving #DirectCompass #AucklandArchitecture #CedarCladding #ZenGarden #OpenPlanLiving

OEO Studio, based in Copenhagen, has completed a luxury apartment in Tokyo's Opus Arisugawa Terrace & Residence, collaborating with Japanese property developer ReBita. The project seamlessly integrates Scandinavian design principles with traditional Japanese aesthetics and materials, reflecting a cross-cultural design philosophy. The apartment showcases OEO Studio's expertise in creating spaces that are both clean and rich in local character. The interior design features a kitchen crafted in Denmark by Garde Hvalsøe, known for its handcrafted cabinetry, and furniture from prominent brands such as Gubi, Stellar Works, and Brdr Krüger in the living room. Art pieces by Finnish artist Jaakko Mattila and Danish photographer Søren Rønholt further enhance the Scandinavian influence. The apartment’s layout promotes a natural flow between designated areas, fostering a warm and inviting atmosphere. Textural elements are central to the design, with rammed earth walls in the entryway providing a connection to nature, and columns made from Japanese Ōya stone dividing the living and kitchen spaces. Entrance areas are distinguished by deep blue indigo tiles, while Finnish birch paper yarn rugs, featuring patterns inspired by traditional Japanese textiles, introduce tactile comfort. The flooring creates visual interest through a juxtaposition of stone in the living room and wood in adjacent areas. A notable design feature is a movable wall that allows for flexible privacy settings. The bedrooms explore contrasts, with one designed in a darker palette and another in a lighter one, furnished with pieces from Karakter, Brdr Krüger, Stellar Works, and Fritz Hansen. The en-suite bathrooms continue the material narrative with stonework and wooden cabinetry, highlighted by a hinoki wood bathtub. This project exemplifies OEO Studio's ability to blend diverse cultural influences into a cohesive and luxurious living environment. The studio drew upon its established design heritage, integrating it thoughtfully with Japanese traditions to create an apartment that respects both backgrounds while offering a contemporary, elegant aesthetic. The use of natural materials and a focus on craftsmanship underscore the design's commitment to quality and longevity. The combination of Danish and Japanese design elements creates a unique dialogue between minimalist principles and a profound appreciation for texture and natural forms, resulting in a residence that is both sophisticated and deeply rooted in its context. #OEOStudio #TokyoApartment #ScandinavianDesign #JapaneseHeritage #InteriorDesign #LuxuryLiving #CrossCulturalDesign #NaturalMaterials
