ryuichi ashizawa sets spiral family house with roof garden on awaji island in japan

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

Apollo Architects and Associates have designed a Japanese residence, dubbed 'Grid House,' that seamlessly integrates the client's extensive collection of artwork and furniture into its architectural fabric. Located in a tranquil Japanese neighborhood, the firm opted for a reinforced concrete structure featuring a low-profile and non-intrusive aesthetic, harmonizing with its serene surroundings. The exterior and interior maintain a consistent muted, monochromatic color scheme, acting as a neutral canvas to accentuate the displayed art pieces. A distinctive feature of the residence is the concrete coffered ceiling in the family room, divided into a 1.2-meter-square lattice. This design draws inspiration from traditional Japanese architecture, particularly temples and sukiya-style structures like tea houses. Natural light enters through clerestory windows on the north and south sides, softened by extended eaves that impart a light and floating character to the building. Beyond its structural role in supporting the roof, the latticed ceiling transforms the dwelling into a minimalist artwork itself. The floorplan is characterized by its straightforward layout. A central lounge area effectively frames an adjacent courtyard, creating a visual connection between indoor and outdoor spaces. Bedrooms are strategically positioned in the wings on the opposite side, ensuring privacy and separation from the main living area. This arrangement establishes a sense of symmetry that is often observed in Western architectural styles, further enhanced by the inclusion of steps and a private courtyard accessible from only one side. The design period for this project spanned from July 2013 to December 2016, with construction taking place between December 2015 and December 2016. Key project details include a total site area of 308.81 square meters and a total floor area of 126.44 square meters. The structural engineering was handled by Masaki Structure Laboratory, with Kenta Masaki as the lead structural engineer. Naoki Matsumoto was responsible for mechanical engineering, and Sirius Lighting Office managed the lighting design. The exterior and interior finishes predominantly feature exposed concrete for walls and ceilings, complemented by tile flooring. The lighting scheme exclusively utilizes LED fixtures, contributing to both the aesthetic and energy efficiency of the home. This meticulous attention to detail in material selection and spatial planning underscores the architects' commitment to creating a residence that is both functional and a contemplative space for its inhabitants and their cherished collections. #ApolloArchitects #JapaneseArchitecture #ConcreteDesign #CofferedCeiling #ResidentialArchitecture #ArchitecturalIntegration #MinimalistDesign #ArtisticHome #ReinforcedConcrete

The 'Kusatsu House' in Shiga, Japan, designed by Hearth Architects, is a family home structured in an L-shape to embrace a central, tree-planted courtyard. This architectural decision was driven by the clients' desire for a home with a garden where family members could relax and interact, fostering a sense of togetherness. The L-shaped layout effectively integrates nature into the common living areas, creating a lively and engaging atmosphere within an otherwise understated interior palette. The design thoughtfully connects the indoor and outdoor spaces through extensive floor-to-ceiling openings, allowing abundant natural light to penetrate the home and blurring the lines between the interior and exterior environments. This approach enhances the feeling of openness while maintaining privacy. To balance openness with the need for seclusion, the veranda is enclosed by a concrete wall, offering a more private and introverted outdoor space. The design also incorporates traditional Japanese architectural elements, particularly evident in the courtyard. A wooden strip of flooring extends from the interior, effectively expanding the living area into the garden, providing a dedicated space for relaxation and connection with nature. The interiors are characterized by warm, natural tones, and a deliberate absence of excessive decoration, contributing to a minimalist and serene aesthetic. A notable feature is a small, separate Japanese-style room, which fulfills a specific client request. This room is distinguished by its vibrant colors, traditional tatami flooring, and an opaque opening that allows dim light to enter without compromising privacy. The project details confirm that the Kusatsu House was completed in February 2020. It spans a site area of 160.41 square meters, with a building area of 65.21 square meters and a total floor area of 99.36 square meters. Photography for the project was done by Yuta Yamada. Hearth Architects successfully met the clients' brief by creating a harmonious living environment that celebrates both communal interaction and individual privacy, all while deeply connecting with its natural surroundings through thoughtful design and traditional influences. The house stands as a contemporary example of Japanese residential architecture that prioritizes natural light, spatial fluidity, and a calm, inviting atmosphere. #LShapedHouse #HearthArchitects #KusatsuHouse #JapaneseArchitecture #CourtyardDesign #ResidentialArchitecture #NaturalLight #IndoorOutdoorLiving #MinimalistInterior

MDS, a Japanese architectural firm, has designed and constructed the 'Okazaki House,' a single-storey residence featuring a distinctive pitched shed roof. This project addresses the increasing trend in Japan of multi-generational living, specifically the demand for dwellings built on the property of a client's parents. The house is situated adjacent to the owner's parents' home in Okazaki-city, Aichi, Japan, and was completed in 2012. The site itself presents a natural slope from north to south and also towards the west, where the existing family home is located. This topographical advantage allows the new 'Okazaki House' to be positioned on an elevated spot, providing its inhabitants with expansive views of the sky. The design incorporates a unique internal arrangement where the floor levels of the rooms are dynamically influenced by the natural ground height of the building's footprint. The interior layout is characterized by two strategically placed canted, or angled, walls that delineate the open-plan space into distinct living zones. The main bedroom is located on the highest part of the site, specifically the north-east side. From this point, the interior slopes downwards, passing through a central courtyard before reaching the living room, which seamlessly transitions into the dining and kitchen areas. This thoughtful arrangement ensures that occupants can maintain a consistent eye-level perspective across the interior spaces, fostering a sense of interconnectedness while also defining separate functional zones and a feeling of distance. A key architectural feature of the 'Okazaki House' is its exposed cedar framework for the roof. This framework is constructed using standard 120 x 120mm lumber pieces. The beams are laid within the maximum standard length of 6 meters and are artfully criss-crossed at the upper sections of the canted interior walls. This construction method not only provides structural integrity but also creates a visually striking ceiling surface that is appreciated both from inside the home and from its exterior. The total floor area of the residence is 98.17 square meters on a site area of 213.74 square meters. The material palette for the house includes exterior finishes of Yakisugi (charred cedar) and exposed concrete, which contribute to its contemporary aesthetic and durability. The roof is made of galvanized color steel sheet with standing-seam roofing. Inside, the floors are finished with oak flooring, the walls are plastered, and the ceiling showcases the exposed Oregon pine of 120x120mm, highlighting the structural beauty. The design by Kiyotoshi Mori & Natsuko Kawamura of MDS demonstrates a considered approach to site integration, spatial organization, and material expression, resulting in a residence that responds to both family dynamics and environmental conditions in Japan. #MDSArchitects #JapaneseArchitecture #OkazakiHouse #ShedRoofDesign #SingleStoreyHome #ResidentialDesign #CedarFramework #SlopedSiteDesign #ArchitecturalInnovation

Furuya Design has meticulously transformed an existing wooden bungalow on Amami Ōshima into a SANU Second Home, deeply integrating it with the island's subtropical environment. Situated in Tatsugo Town, near Amami Airport and overlooking Akaogi Bay, the project is part of SANU's membership-based vacation home network. The site is characterized by its tranquil inland sea, coral stone foundations, and resilient akagi trees, which have adapted to the strong ocean winds. The design philosophy behind this renovation focused on blurring the lines between the built structure and the surrounding natural landscape, emphasizing framing, texture, and creating an immersive atmosphere. The architects addressed the compact footprint of the original bungalow by introducing robust, expressive exterior walls, creating a double-skin facade. This innovative approach integrates existing elements like storm shutters and aluminum sashes while enhancing the home's performance and aesthetic appeal. The outer layer, clad in wood, is designed to mimic the textured, layered appearance of local fan palms, creating dynamic shadow play throughout the day. A crucial design intervention involved elevating a new attic-level viewpoint. This addition provides occupants with a unique vantage point to observe the coastline, framed by palm fronds, and to experience the sensory input of shifting leaves and distant surf, establishing a profound connection to the natural soundscape. Internally, Furuya Design implemented a significant vertical expansion by removing the original ceiling. This created a double-height atrium, linking the newly added attic viewpoint with the main living areas below. This central space functions as an indoor balcony, serving as a transition zone between the comfort of the interior and the expansive outdoors. The floor plan radiates from this atrium, incorporating distinct zones for living, dining, sleeping, and utility, ensuring a flexible layout suitable for both private contemplation and communal activities. The interior design prioritizes permeable boundaries, with carefully positioned openings that frame specific views of the landscape, drawing inspiration from the art of Isson Tanaka, known for his depictions of Amami's natural beauty. The renovation also paid close attention to Amami's unique botanical character, where tropical plants like hibiscus, plumeria, and bougainvillea flourish outdoors year-round, unlike their indoor cultivation in colder climates. Furuya Design collaborated with a local botanical garden to augment the site's existing vegetation, selecting species native to the island to enhance the ecological richness of the grounds. This botanical focus extended to a broader ecological consideration, particularly in light of the pest damage affecting sago palms, a symbolic species on Amami. The project became an opportunity to reflect on the role of architecture not only in preserving natural aesthetics but also in fostering a deeper engagement with and responsiveness to natural ecosystems facing environmental challenges. This partnership with SANU underscored a commitment to addressing the declining natural systems and promoting environmental awareness through architectural design and landscaping choices. #FuruyaDesign #SANUHome #AmamiOshima #JapaneseArchitecture #BungalowRenovation #NatureImmersedDesign #WoodArchitecture #SubtropicalEnvironment #ArchitecturalRenovation

Ryuji Yamashita Architects has designed a two-story residence in Hokkaido, Japan, for a family with four children, emphasizing connection and interaction among siblings while still providing individual private spaces. The design incorporates open floor layouts and timber accents, creating a warm and inviting atmosphere. A central playroom on the first floor serves as the primary meeting point, linking all four children's rooms. This common area is intentionally designed to foster a sense of togetherness, preventing the potential isolation that separate private rooms might otherwise create. To enhance the playful nature of the space, a 70 cm height difference exists between the bedrooms and the common playroom, necessitating steps at each entry point from the ground floor and from each child's room. The architect integrated thoughtful features to encourage ongoing interaction. A large window provides ample natural light to the playroom, and two types of openings further reinforce familial bonds. Glass tiles are strategically placed within the wooden flooring outside the private rooms, creating a visual connection between the two floors and allowing light to filter through. Additionally, each child's room features a small window positioned just above their desk. When these windows are open, the first floor transforms into a large, integrated study area, facilitating direct interaction and collaboration among the siblings. This innovative design offers a flexible environment that adapts to the children's needs for both privacy and shared experiences. The 'With four children' house, completed in October 2021, measures 69.56 sqm for the building area and 125.65 sqm for the total floor area. The project was constructed by Kobayashi Shoten Co., Ltd, with photography by Ikuya Sasaki. This architectural approach by Ryuji Yamashita aims to transcend the traditional binary of private versus large rooms or individual versus group settings. Instead, it seeks to establish a dynamic space where family members can connect through various senses of distance, offering a balance between personal retreat and collective engagement. The design prioritizes the development of strong sibling relationships through carefully considered architectural elements that promote both visual and interactive connectivity within the home. #RyujiYamashitaArchitects #JapaneseArchitecture #FamilyHomeDesign #SiblingBonds #PlayroomDesign #OpenConceptLiving #TimberAccents #Hokkaido #ResidentialArchitecture

The "Courtyard House with Seven Rooms" project, designed by Takayuki Kuzushima and Associates, is a residential property located in the suburbs of Nishio, Aichi Prefecture, Japan. Completed in 2022, the house spans an area of 95 square meters and was constructed with structural support from Komatsu Structural Design. The design process for this house was unique, starting from the owner's extensive collection of architectural and interior design images sourced from social media and magazines. This collection included a diverse range of aesthetics and functional ideas, from bare concrete exteriors and wood-paneled facades to minimalist and eclectic interiors, alongside practical storage solutions and antique furniture preferences. Faced with a seemingly disparate set of inspirations, the architects opted against a selective approach to integrate these varied elements. Instead, their design philosophy focused on creating a foundational framework capable of accommodating and harmonizing this overflow of diverse and potentially evolving preferences. The core concept revolves around an "open room to room" strategy within a "build room in town" context. This approach aimed to foster a continuous and adaptable living environment that could embrace the owner's changing tastes over time, rather than confining them to a rigid, pre-defined style. The house is characterized by the use of wood and steel as primary materials, reflecting a blend of traditional and contemporary Japanese architectural elements. The design likely incorporates a courtyard, as suggested by the project title, to introduce natural light and ventilation while maintaining privacy in a suburban setting. The "seven rooms" could refer to distinct functional zones or spaces within the house, each potentially reflecting a different aspect of the owner's collected inspirations, yet interconnected through the overarching design framework. The emphasis on adaptability and the ability to integrate diverse aesthetic preferences suggests a highly personalized and flexible living space. This project exemplifies an architectural response to the modern homeowner's desire for a custom-built environment that can evolve with their lifestyle, moving beyond a single, static design vision. #ResidentialArchitecture #Houses #Nishio #JapanArchitecture #CourtyardHouse #JapaneseDesign #ArchitecturalInnovation #WoodConstruction #SteelStructure

Tamada & Wakimoto Architects have completed the 'Roof House' in the rural outskirts of Tochigi, Japan, on a former farmstead surrounded by rice fields and small factories. This residence is designed to integrate daily life with its garden surroundings. The project is situated on a 2,000-square-meter plot, which previously held a large farmhouse and was framed by hardwood trees. The client, a young individual relocating from the city, sought a space that could facilitate living, working, and social connection, while also offering adaptability for future needs. The architects responded to this brief by disaggregating the house into several compact buildings, which are then strategically arranged around semi-outdoor courtyards. These intermediate spaces, referred to as 'earthen floor' gardens, are unified beneath a single, thin, and extended roof. This design approach results in a relaxed, low-slung architectural form that encourages fluid movement between indoor rooms and outdoor areas. This integration allows the surrounding landscape, prevailing weather conditions, and local daily rhythms to significantly influence and shape the occupants' interaction with the house. The design of Roof House imbues each side with a distinct character. The main garden is oriented towards the existing trees, and an outdoor kitchen is incorporated for cooking and social gatherings, particularly during the spring cherry blossom season. Near the entrance, a shaded zone beneath the eaves serves as an informal space for sitting, conversing, or receiving visitors. To the north, a walled garden provides a dedicated area for weekend activities such as carpentry or car maintenance, reflecting common rural pursuits. Central to the Roof House's concept is its inherent adaptability. The architectural plan allows for future reconfigurations over time. For instance, the private section of the house, which includes the bedroom and bath, could continue to function as a vacation home. Concurrently, other segments of the structure are designed with the flexibility to be repurposed, potentially serving as a small retail shop or an art gallery. This forward-thinking design ensures the residence can evolve with the client's changing needs and aspirations, maintaining its utility and relevance in the long term. #JapaneseArchitecture #ResidentialDesign #GardenIntegration #AdaptableArchitecture #RuralLiving #CourtyardHouse #ArchitecturalInnovation #TamadaWakimotoArchitects

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

Seiichi Yamada and Associates have completed 'House in Nishichiyoda,' a private residence in Shizuoka City, Japan, featuring a distinctive operable silver facade. This innovative exterior design allows the home to transform its relationship with its surroundings. When fully closed, the reflective surface mirrors the environment, including passersby and the natural foliage, effectively blurring the house's physical presence. This creates a sense of integration and chameleon-like adaptability within the landscape. The facade's dynamic nature is further emphasized when individual walls open, creating dark apertures that allow sharp beams of light to penetrate the interior. This controlled influx of light creates a dramatic interplay of shadow and illumination, shaping the atmosphere within the house. When all walls are opened, the boundaries between the interior and exterior dissolve, creating a seamless connection and allowing abundant natural light to flood the living spaces. The architects describe this process as analogous to a monk's daily ritual of opening and closing fittings, suggesting that these small, deliberate actions contribute to a unique way of living within the home. This architectural approach aims to foster a mindful engagement with the building and its environment. The design philosophy behind 'House in Nishichiyoda' is rooted in a contemporary reinterpretation of traditional Japanese housing styles. Seiichi Yamada and Associates sought to evolve existing architectural traditions rather than simply replicate them, aiming to construct a Japanese house for the future without succumbing to nostalgia. The structural integrity of the building is achieved through a unique construction method involving cypress pillars. These pillars are erected on the outer periphery of a 3 x 6 angle at a 900 mm pitch and are interconnected to form a gable roof. Flat lattice beams, assembled at an 1,800 mm pitch, are then stacked, shifted by 900 mm to the left and right, to create a robust beam frame. This intricate system of interconnected pillars not only ensures the slenderness ratio is maintained but also incorporates a heat-insulating layer, contributing to the energy efficiency of the residence. The result is a frame that appears to float like a cloud within the building's interior, adding a sense of lightness and openness to the design. The three levels of the house are vertically connected by a wooden staircase, which acts as a central spine for circulation. A small light source positioned within the frame illuminates the ground floor, enhancing the sense of vertical connection and bringing natural light deeper into the home. The project's name, 'House in Nishichiyoda,' reflects its location in Shizuoka, Japan. The architects, Seiichi Yamada and Associates, have demonstrated a commitment to innovative design that respects cultural heritage while embracing modern architectural principles. The house is a testament to how an operable facade can redefine spatial relationships, control light, and integrate a dwelling with its natural and urban context, offering a new perspective on residential architecture in Japan. #OperableFacade #JapaneseArchitecture #WoodenHouse #SeiichiYamadaAndAssociates #ShizuokaJapan #ReflectiveExterior #NaturalLight #SustainableDesign #ResidentialArchitecture

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

The 'Double Roof House,' designed by the Japanese firm SUEP. (Hirokazu Suemitsu + Yoko Suemitsu), integrates a distinctive catenary curve feature that serves both aesthetic and functional purposes. Located in a low-rise residential area of Yamaguchi, Japan, the house is specifically designed to mitigate solar gain due to the lack of surrounding shadows on the site. The structure is a single-story building characterized by its two roofs and a composition of five individual box-shaped units, each designated for a specific function within the home. A central element of the design is a dramatic floating 'sudare,' or reed screen, positioned above the main structure. This screen plays a crucial role in passive solar design by effectively reducing solar heat gain into the building by 50%. A deliberate small gap is maintained between the two roof structures, allowing for the diffusion of natural light into the interior spaces while still providing shade. The overall design of the house is harmoniously integrated with its natural surroundings, following the site's topography to sit comfortably within the landscape. The project details indicate a substantial land size of 1,326.1 square meters, with a building area and total floor area both measuring 235.2 square meters. The house is constructed using a wooden bungalow structure, emphasizing a connection with natural materials and possibly contributing to a lighter environmental footprint. The internal layout, though consisting of separate box-shaped units, is visually unified by the overarching double roof system, which also serves to connect the various spaces. Photographs by Kai Nakamura showcase the exterior and interior aspects of the residence. An external view highlights the visual connection provided by the two roofs across the distinct units. Interior shots capture the kitchen and living areas, demonstrating how natural light filters into these spaces despite the sun-shading mechanisms. The entrance, positioned beneath the floating double roof, creates a welcoming and sheltered approach. Another interior view offers a broader perspective of the 'Double Roof House,' emphasizing the thoughtful integration of design elements. A night view of the residence reveals its illuminated presence in the landscape. Supporting illustrations include a rendering of the house, a site plan detailing its placement, and a plan and section drawing that provide technical insights into the building's layout and structural components. These illustrations collectively articulate the architectural vision and the functional considerations behind the 'Double Roof House' project. #SUEP #DoubleRoofHouse #JapaneseArchitecture #SustainableDesign #PassiveSolar #ReedScreen #WoodenBungalow #ResidentialArchitecture

Kichi Architectural Design has completed the House of Kubogaoka, a cube-shaped residence in Ibaraki Prefecture, Japan. The house features small square windows intermittently placed across its facades. The structure utilizes a timber framework, but its front and rear facades are finished with plaster, providing the appearance of solid concrete construction. In contrast to these two facades, the side walls of the house are painted white. According to the architects, the use of white on the side walls creates a clear visual distinction against the basic mortar color of the other exterior walls. The main entrance of the house is created by an apparent cut-away section at one corner of the cube. Upon entering, a corridor extends directly through the house to a terrace located at the rear. This corridor features a dark tiled floor, which the architects liken to the traditional earth floors found in older Japanese homes. This design element aims to evoke a sense of historical Japanese dwelling immediately upon entry, extending the concept of an 'earth-floored room' to the outdoor yard beyond. The interior of the house introduces varying floor levels and materials to define different spaces. The main living area of the first storey is raised by two steps from the entrance corridor. This change in elevation is accompanied by a transition in flooring material, moving from the dark tiles of the corridor to a wooden surface. Further into the house, this wooden surface then gives way to a grid of tatami mats, forming a traditional Japanese room. The architects state that this combination of tatami and tiles harmonizes Japanese and Western interior styles within the residence. The traditional Japanese room is designed with sliding partitions, allowing it to be separated from an adjacent long, narrow space. This adaptable space serves multiple functions as a combined living room, dining room, and kitchen. This layout facilitates an open-plan living environment while retaining the option for privacy or distinct area definitions through the use of traditional sliding screens. An outdoor dining area is integrated into a recess at the back of the house. This area is strategically aligned with a sheltered balcony on the upper floor, suggesting a vertical connection between the outdoor spaces. A staircase, constructed with wooden treads, provides access to the upper storey. The upper floor accommodates two bedrooms, which are situated along opposite walls, with a second tatami room positioned between them. Photography for the project was carried out by Ippei Shinzawa. Floor plans for both the ground and first floors, as well as a cross-section, are available to illustrate the layout and design. #ResidentialArchitecture #JapaneseHouses #KichiArchitecturalDesign #IbarakiPrefecture #CubeHouse #TatamiRooms #TimberConstruction #ArchitecturalDesign

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

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 "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
