Formafatal creates pair of rammed-earth villas in Costa Rica

The Achioté project by Formafatal introduces the first rammed earth structures in Costa Rica, presenting a pair of minimalist villas available for rent in Playa Hermosa. These villas, named Jaspis and Nefrit, appear to float above a cliff overlooking the Pacific Ocean, harmoniously integrated into a dense jungle environment. Dagmar Štěpánová of Formafatal led the design and construction, prioritizing sustainability and minimal environmental impact throughout the process. The conceptualization of the villas drew from the distinct energies of their respective locations. The Jaspis Villa, symbolizing jasper and bright aspects, embodies a yin energy, connecting with the sky and ocean, and features a light, sandy color palette. In contrast, the Nefrit Villa, representing jade and darker tones, aligns with a yang energy, establishing a connection to the earth and the surrounding jungle, characterized by a deep red-terracotta hue. Both villas boast cantilevered roofs that extend outward, mirroring the floor plans, to provide essential protection from the sun and various weather elements inherent to the tropical climate. A significant aspect of the villas' construction involved utilizing the very clay soil excavated from the site to create the rammed earth walls. This sustainable approach minimized the need for imported construction materials, contributing to the project's ecological footprint. Once the structures were complete, new tropical plants were integrated into the landscape, further enhancing the natural surroundings. The layered texture of the rammed earth walls is a prominent design feature, visually narrating the construction process. Each villa spans 90 square meters (approximately 969 square feet) and shares an identical size, layout, and orientation. Despite these similarities, their material choices and color schemes are distinct, reflecting their individual energetic inspirations. The central feature of each villa's interior is the bed, which can be enclosed by sliding curtains for privacy and mosquito protection, while frameless glass walls offer uninterrupted views of the natural landscape. An additional bed is available on the terrace for outdoor relaxation. Adjacent to each villa are built-in pools, designed to create an immersive jungle swimming experience. To execute the complex rammed earth construction, Formafatal collaborated with Brazilian specialist Daniel Mantovani of Terra Compacta, who provided training to local craftsmen. The interior spaces behind the beds house the kitchens and bathrooms, designed without doors to maintain an open and fluid connection within the living areas. Custom-made concrete elements, including bathroom sinks, shelves, kitchen counters, and bedside tables, are integral to the design, reflecting a cohesive material palette. The Nefrit Villa distinguishes itself with a darker, more introspective color scheme compared to its counterpart, despite their structural similarities. #AchioteProject #Formafatal #RammedEarth #CostaRicaArchitecture #SustainableDesign #TropicalVillas #EcoFriendlyHomes #JaspisVilla #NefritVilla

Rammed-earth construction, a technique thousands of years old with origins in China and the Iberian Peninsula, offers numerous benefits for contemporary home building. Examples such as the original rammed-earth sections of the Great Wall and the Alhambra palace in Spain demonstrate its historical durability. This method is favored by Terrell Wong, principal of Stone’s Throw Design, due to its low embodied energy, recyclability, high thermal mass, low energy loads, and non-toxicity. Wong highlights its longevity, stating that a rammed-earth house can last 500 years or more, requiring no painting. These walls function as the structure, insulation, finish, and thermal mass of a building. The construction process involves creating panels approximately 11.5 feet long from a mixture of 20% to 30% clay and sand, with 5% to 10% cement. In colder, wetter climates, a silicate-based waterproofing agent is often incorporated. Walls are built in layers, or lifts, where one foot of material is placed into formwork and compressed to six inches using a pneumatic tamper. The forms, typically made of HDO plywood and lumber, are about 20 inches wide and 4 feet tall. When constructing walls longer than a single panel, a recess on one end of the first panel allows the subsequent panel to interlock, ensuring structural integrity. Conduit for plumbing and electrical wiring must be planned precisely, as these cannot be altered once the wall is erected. Rammed-earth walls are typically dry and load-bearing within 24 hours, exhibiting compressive strength comparable to concrete, usually between 1600 psi and 1800 psi for 2-foot-thick walls. Rammed earth is particularly effective as a thermal mass, absorbing and storing solar radiation during the day and re-radiating it at night. This property helps maintain consistent indoor temperatures and humidity levels, reducing reliance on mechanical heating and cooling systems. Many modern rammed-earth homes are hybrids, combining rammed earth with other construction methods like stick or timber-frame walls, or even straw-bale construction for upper floors. Cross-laminated timber (CLT) panels can also be used for roofs. Wong frequently integrates rammed earth for interior partition walls as well. A case study highlights a single-family home designed by Wong in a rural, woodland setting. This home incorporates Passive House strategies, maximizing the thermal mass of rammed earth, harnessing southern light, and utilizing cross breezes for passive ventilation. The effective natural cooling eliminates the need for mechanical air conditioning, and the house consumes only about 20 kW of heat annually. The exterior walls, composed of 530 tons of material with two 6-inch wythes of rammed earth sandwiching 6 inches of insulation, benefit from locally sourced materials, resulting in exceptionally low embodied energy. Recycled wooden formwork was also repurposed for interior use. Beyond energy efficiency, rammed-earth walls offer soundproofing qualities due to their thickness. The absence of organic matter in the material prevents mold growth, contributing to superior indoor air quality. Sylvia Cook, principal of Aerecura Rammed Earth Builders, emphasizes that the thermal mass benefits are equally significant in both hot and cold climates, stabilizing internal temperatures. The technique remains a fringe method in many regions, including Canada, primarily due to a lack of awareness and specific building codes in North America. While other countries like Australia and New Zealand have formalized codes, in Canada, practitioners demonstrate compliance by showing rammed earth's similarity to concrete or concrete block, often incorporating rebar in colder, wetter climates and recycled polyiso insulation to minimize thermal bridging. The aesthetic appeal of rammed-earth walls is characterized by earth-toned striations, created by adding pigment to the cement and allowing the ramming process to push colors to the visible outermost layer. The amount of material in each layer can be varied to enhance these natural color patterns. While complex designs with curved or angled walls can increase costs due to the labor-intensive nature of the method, Wong has successfully applied rammed earth to affordable housing projects by simplifying the design and formwork. Test cylinders filled with rammed earth are used to measure psi before and during construction to ensure engineering code compliance. #RammedEarthConstruction #SustainableBuilding #GreenBuilding #ThermalMass #EnergyEfficiency #DurableHomes #EcoFriendlyMaterials #ArchitecturalDesign #PassiveHouse

The Desert Wash home, a 6,700-square-foot modern residence in Paradise Valley, Arizona, was designed by architect Brent Kendle of Kendle Design Collaborative for clients Keith and Becky. The initial challenge for the design was a desert wash that bisected the building site, which the owners initially viewed as a hindrance. However, Kendle embraced this natural feature, transforming it into a central element of the home’s design and ethos. The architect's vision was to create a contemporary residence with minimal site impact, integrating the structure harmoniously into its desert surroundings. The home's design is divided into three distinct parts. The southern section houses the entrance, a guest suite, and an office. This compact volume is connected to the main body of the house, situated to the north, by an enclosed bridge. This bridge is elevated above the desert wash, allowing periodic floodwaters and local wildlife to pass underneath undisturbed. This innovative structural solution not only preserves the natural flow of the wash but also provides unique views and experiences from within the home, making the natural landscape an intrinsic part of daily life. To ensure the house blended seamlessly with its environment, Brent Kendle utilized a material palette and design elements that echoed the desert landscape. Rammed earth walls, constructed from soil excavated directly from the site, are a prominent feature, providing a direct physical connection to the land. This choice of material contributes to the home's eco-friendly credentials and offers natural insulation properties. A neutral color palette further enhances the integration, making the structure feel as if it has emerged organically from the desert. Expansive glazing, including Fleetwood sliding pocket-doors, is used throughout the residence to blur the boundaries between indoor and outdoor living. This allows for continuous visual and physical access to the surrounding desert, fostering a deep connection with nature. Outdoor living rooms are strategically integrated into the design, extending the habitable space and providing shaded areas for relaxation and enjoyment of the natural surroundings. Douglas Fir soffits and integral color-synthetic stucco for exterior walls complement the rammed earth, creating a cohesive and visually appealing facade. From various points within the home, such as the open great room and the master suite, sweeping views of the desert wash and the broader landscape are framed. The master bedroom features a corner window specifically designed to capture these views, while a freestanding soaking tub in the master bath is strategically placed beneath another shaded corner window. The interior also features Verano-brushed 12x24 limestone flooring in the great room, which benefits from ample natural light. The kitchen boasts a three-inch Calcutta Prima slab on the range wall and backsplash, adding a touch of elegance to the natural material scheme. Keith, one of the homeowners, noted that the wash, rather than being an obstacle, has become a "freeway" for local wildlife and an endless source of entertainment and educational opportunities for their two young children. The design emphasizes site-sensitivity, respecting the natural topography by nestling into the earth while spanning over the ancient wash, thereby minimizing disruption and maximizing the symbiotic relationship between the built environment and the natural desert ecosystem. #EcoFriendlyHome #RammedEarthWalls #DesertArchitecture #SustainableDesign #ModernResidence #SiteSensitiveDesign #IndoorOutdoorLiving #ArizonaHomes #KendleDesignCollaborative

Rammed earth construction, an ancient technique originating independently in China and the Iberian Peninsula several thousand years ago, is gaining recognition for its numerous green building benefits. This method, utilized in structures like the Hakka Tulou in China and the Alhambra Palace in Spain, offers low embodied energy, recyclability, high thermal mass, low energy loads, and non-toxicity. Terrell Wong, principal of Stone’s Throw Design Inc. in Ontario, Canada, advocates for rammed earth, highlighting its durability and longevity, asserting that a rammed earth house can last 500 years or more without needing paint. Rammed earth walls are constructed in approximately 11.5 ft. panels with flexible joints. The material mix typically includes 20% to 30% clay, sand, and 5% to 10% cement for added strength, with silicate-based waterproofing sometimes incorporated for cold, wet climates. The process involves layering a foot of material into formwork, which is then compressed to 6 inches using a pneumatic tamper. The forms, usually made from Marine-grade plywood and 2x12 walers, are about 20 inches wide and 4 feet tall. For multi-panel walls, a recess on the first panel locks with the second. Conduits for plumbing and electrical wiring are integrated during construction, requiring precise planning as changes are impossible once the wall is set. Walls typically dry within 24 hours and possess a load-bearing capacity comparable to concrete. Despite its ancient origins and proven effectiveness, rammed earth construction remains a niche method in North America. Terrell Wong designs three to four rammed earth houses annually, noting only a handful of builders in Ontario specialize in this technique. Sylvia Cook of Aerecura Rammed Earth Builders emphasizes that the method's thermal mass benefits apply universally, delaying heat gain in hot climates and shifting heat loss in cold climates to periods when solar gain can compensate, thus maintaining consistent indoor temperatures. The limited adoption is primarily attributed to a lack of public and professional knowledge about the system’s versatility across different climates. The distinctive earthy-toned striations characteristic of rammed earth walls are achieved by adding pigment to the cement mix. The ramming process pushes the colors to the formwork edges, creating a natural gradation. Exaggerating the undulations in the formwork can enhance these visual effects. While modern rammed earth construction has advanced, North America lacks specific building codes for it, unlike Australia and New Zealand where codes are formalized, and research even suggests superior seismic resistance compared to brick or block walls. In Canada, builders obtain approval by demonstrating that rammed earth meets existing code requirements, similar to concrete. In colder regions like Ontario, fiberglass rebar is used for structural stability, and recycled polyiso insulation is often integrated into the walls to minimize thermal bridging. The cost of rammed earth projects is influenced by design complexity, with curved or angled walls being more expensive due to the labor-intensive nature of the method. However, by simplifying design and formwork, Terrell Wong successfully applied the technique to an affordable housing project meeting Passive House standards. Many rammed earth homes are hybrids, incorporating elements like stick- or timber-frame walls for interior partitions or upper floors, sometimes combined with straw-bale construction or CLT-panel roofs. The featured single-family home, situated in a rural Ontario subdivision, exemplifies the integration of rammed earth with Passive House strategies. The design maximizes thermal mass, harvests southern light, and utilizes cross breezes to enhance passive ventilation, eliminating the need for mechanical cooling. The home's heating demand is approximately 20 kWh/m2 annually. The exterior walls consist of 530 tons of thermal mass, comprising two 6-inch rammed earth wythes around 6 inches of insulation. The construction’s embodied energy is exceptionally low, as 90% of the unprocessed material was sourced from a nearby gravel pit, and salvaged wood from a local roundhouse was repurposed for the main stair. #RammedEarthConstruction #SustainableBuilding #GreenBuilding #ThermalMass #PassiveHouse #BuildingMaterials #EcoFriendlyHomes #ArchitecturalDesign #CanadianArchitecture

The 'Libertad Street House,' a two-storey dwelling in Montevideo, Uruguay, was designed by architects Pedro Livni and Karin Bia to prioritize privacy and flexible living. The primary living spaces are situated on the ground floor, shielded from the street by a predominantly opaque facade, ensuring seclusion for its inhabitants. These ground-level areas feature an open-plan layout, which can be reconfigured as needed using mobile walls, allowing for adaptable partitioning of the space according to the user's discretion and current needs. Towards the rear of the property, the lounge area seamlessly extends onto an outdoor terrace, which is equipped with a barbecue area, fostering an environment suitable for relaxation and social gatherings. A central design element is the staircase, strategically placed within a double-height hallway at the core of the home. This positioning serves multiple functional purposes: it effectively organizes the floor plan, facilitating clear distribution between different zones of the house, and crucially, it allows natural light to penetrate deeply into all areas of the residence, enhancing its brightness and spatial quality. The upper storey of the Libertad Street House accommodates the more private functions of the home. It houses three bedrooms, each designed to overlook the backyard, providing peaceful views and a sense of retreat. The master bedroom is uniquely positioned at the furthest edge of the plot, offering maximum privacy and an exclusive connection to an external veranda. This veranda is a notable feature, incorporating a rooftop hot tub, which introduces an element of luxury and offers an elevated outdoor living experience. Throughout the design, a carefully chosen, restrained material palette defines the aesthetic and structural integrity of the house. Reinforced concrete is extensively utilized for both the slabs and vertical surfaces, contributing to a robust and contemporary architectural language. This choice of concrete is complemented by the integration of warmer wooden tones, which are applied to the floors and various dividing elements, introducing a tactile contrast and a sense of warmth to the interiors. The combination of these materials creates a balanced and sophisticated atmosphere within the residence, blending modern architectural principles with inviting domestic comfort. The overall design emphasizes a thoughtful approach to space, light, and material application, resulting in a residence that is both functionally efficient and aesthetically refined. #UruguayanArchitecture #ConcreteHouse #ModernDesign #FlexibleLivingSpaces #OutdoorLiving #ResidentialArchitecture #PedroLivni #KarinBia #Montevideo

The Itamambuca Residence, a 4,844-square-foot concrete home in Brazil designed by São Paulo studio Arquitetura Gui Mattos, offers a unique indoor-outdoor living experience amidst a verdant rainforest near a beach. The home's orthogonal structure is set on a concrete slab slightly raised off the ground, a design choice that serves multiple functional and aesthetic purposes. This elevated foundation functions as a step leading to the main living areas on the lower level and enhances the residents' views of the surrounding trees and plants. Throughout the lower level, glazed, sliding walls can be fully opened, blurring the lines between the interior and the natural environment. These walls are strategically placed a short distance from the edge of the raised concrete floor, creating sheltered terrace decks. These outdoor spaces provide a perfect setting for the owners to relax, enjoy the garden views, or overlook the adjacent pool, fostering a deep connection with nature. Above the main living area, the roof structure is another concrete slab, but ingeniously designed as an inverted prism. Its tip points downwards from the center of the ceiling, causing the central point to slant towards the four corners. This architectural feature creates a sense of openness within the interiors and offers unobstructed sight lines towards the dense jungle surrounding the property. The roof is supported by eight robust concrete columns, which are angled towards the center of the prism. This angling not only provides structural stability but also maximizes the views from inside the home. Beneath this roof, the lower level houses an open-plan living lounge, dining area, and kitchen, all designed to embrace the expansive natural setting. A wooden box structure spans the width of the roof, housing the private quarters. This upper level accommodates the master bedroom, three additional smaller bedrooms, and two bathrooms. Access to this rooftop structure is provided by a staircase situated between two wooden volumes on the lower level. The front of this elevated box features fully glazed walls that open onto a deck, offering spectacular panoramic views of the lush, green jungle, further integrating the home with its natural surroundings. #ConcreteHomes #BrazilianArchitecture #IndoorOutdoorLiving #RainforestHome #ModernDesign #ArchitecturalDesign #NatureIntegration #UniqueRoofStructure

Architects Maria Gomez, Giovanni Ocampo, and Héctor Coss have designed Casa Santos, a low-lying, three-house retreat in Todos Santos, a coastal town on Mexico's Baja Peninsula. The project, located on a 2,000-square-meter desert property with distant sea views, aims to integrate concrete with the desert's aesthetic and address the region's seismic vulnerability. The retreat, which includes three residential buildings and a fourth for service functions, is intended for the Miami Beach-based owners and is also available for rent. The design process prioritized harmony with the natural terrain and resilience against earthquakes. The architects describe Casa Santos as an exploration of concrete's potential to foster community and sustainability within the desert environment. The structures feature ribbed concrete with a pinkish hue, chosen to blend with the natural desert sand and mitigate solar heat gain. The fluting in the walls creates shadows, contributing to passive cooling, while the concrete itself offers thermal relief from the desert heat and structural integrity in an earthquake-prone area. The construction utilized formwork made of rolled-steel sheets, which provided flexibility in placing apertures. After the concrete work was completed, these steel sheets were repurposed for other elements on the property, such as doors, fences, and gates, demonstrating a commitment to material efficiency and recycling. This approach aligns with the project's sustainability goals. The individual homes within Casa Santos share similar layouts, though two have three bedrooms and one has two bedrooms. Each residence includes a kitchen, dining area, and lounge space. The buildings are composed of cube-shaped modules, each measuring 25 square meters, with separate modules for bedrooms/bathrooms and public functions. These modules are intentionally arranged to interact, forming a series of passages, alleys, patios, and squares that evoke the spatial organization of a medieval town. Interior materials include medium-density fiberboard millwork and concrete flooring. The distinctive ribbed concrete walls are left exposed throughout the interiors, providing a consistent aesthetic and tactile quality. The architects emphasize that the walls function as a pure, articulating element, simultaneously serving as interior and exterior surfaces, facades, structural components, and contributing to the overall texture and finish of the spaces. Casa Santos is presented as a contemporary answer to fundamental questions in modern architecture, offering a model for modular construction and scalable accessibility. It incorporates sustainability and climate resilience through its material choices and design strategies. The project achieves an architecture that is austere, formal, and deeply connected to its natural surroundings. Maria Gomez and Giovanni Ocampo lead La Nopalera, and Héctor Coss has his studio, both based in Mexico City. The photography for Casa Santos was done by Jaime Navarro. #MexicanArchitecture #ConcreteDesign #SustainableArchitecture #DesertHomes #ModularConstruction #SeismicResilience #ArchitecturalInnovation #ResidentialDesign #BajaPeninsula

The Tecture-designed Deans Marsh House is a tranquil, light-filled residence nestled in the Surf Coast's hinterland, specifically designed to offer a sense of anticipation and seclusion. The home is accessed via a meandering one-kilometer driveway, intentionally concealing its full form until visitors are well into the property. The initial view is a rammed earth wall with a single opening, revealing little of the interior beyond. This design choice, according to Tecture director and lead architect Ben Robertson, was a deliberate psychological play to create a powerful sense of discovery. The owners, transitioning from urban Newtown to Deans Marsh, sought a calm, quiet, and isolated space that would feel warm and cozy, deeply connected to its rural environment. A central design element is the extensive use of rammed earth walls, each 400mm thick, prominently featured throughout the main living areas as per the homeowners' request. The design maximizes the internal exposure of this material, which also forms a significant part of the home's exterior. This natural, environmentally friendly material, combined with timber cladding, drives the home's façade, ensuring it blends harmoniously with the surrounding landscape. The material palette was chosen to complement the rammed earth's tone, avoiding bright whites in favor of earthy and natural hues to facilitate a seamless transition from the clients' previous urban lifestyle. Internally, the home showcases a calming blend of dark and earthy tones, with consistent use of complementary and contrasting materials such as timber, laminates, and travertine. The design intentionally limited the number of materials to avoid complexity and maintain a cohesive aesthetic. This minimalist approach allows the natural material palette of the exterior to extend inward, especially given the remote location where privacy concerns are minimal, enabling large openings and an indoor-outdoor connection. The house is divided into two distinct sections. The living, kitchen, dining, and main bedroom areas are oriented northward to optimize sunlight and solar gain. A 'kids' wing' is situated to the south, primarily intended for occasional visitors. While an ideal design would have elongated the property to ensure all bedrooms benefited from northern light, budget constraints necessitated prioritizing the primary living spaces. Robertson expressed pride in the outcome, highlighting the home's profound sense of discovery, stillness, tranquility, and refined material application, all contributing to a successful and cathartic living environment. #RammedEarth #SustainableDesign #ArchitecturalDesign #RuralLiving #CoastalHinterland #NaturalMaterials #HomeDesign #Tecture #DeansMarshHouse

Pezo Von Ellrichshausen has completed the 'Loba House,' a concrete structure nestled into the terrain of coastal Chile, overlooking a sea lion reserve on the Pacific Ocean. Described by the architects as "more than a hut but less than a house," the design strategically manipulates perceptions of proportion to achieve a monolithic appearance with an ambiguous scale. The opaque dwelling is situated in the Coliumo peninsula, Tome, VIII region, Chile, covering a built surface of 70 square meters (753 square feet) within a 1,000 square meter (10,764 square feet) plot. The design and construction phases took place in 2016 and 2017, respectively. The architectural concept interprets the building as an "inhabited wall" that runs perpendicular to the natural topography. Its narrow and tall proportion contributes to this perception. The height of this wall is defined by two primary elements: a continuous horizon line provided by the expansive ocean view and a series of six descending platforms that step down towards the sea. This terraced internal structure allows for varying ceiling heights and programmatic divisions within a single, open space. The roof of the 'Loba House' functions as an accessible terrace, serving as an extension of the natural landscape. From this vantage point, a stepped geometric structure offers a dedicated area for observing sunsets, providing an elevated perspective of the surrounding environment. Internally, the dwelling features a single, expansive room, which is strategically punctuated by three substantial concrete columns and two connecting bridges. This layout defines zones without rigid partitioning. Bedrooms are positioned on the higher of the six internal platforms, characterized by lower ceilings, creating a more intimate and enclosed sleeping environment. Conversely, areas designated for communal activities, such as living spaces or dining areas with sofas and tables, are located on the lower levels, benefiting from the greater height and openness. The interior illumination is carefully managed through precisely placed openings on both sides of the elongated volume, complemented by overhead skylights that ensure specific areas within the house receive natural light. A notable design detail is a corner aperture, framed by a round pillar, which features unframed glass flush with the exterior concrete surface, providing an unobstructed view. The construction was undertaken by Carvajal & Cabrer, with structural engineering by Peter Dechent and consultancy by Marcelo Valenzuela and Daniel Garrido. The project exemplifies a harmonious integration with its dramatic coastal setting, blurring the lines between architecture and landscape through its material palette and formal strategy. #ChileanArchitecture #CoastalDesign #ConcreteArchitecture #EmbeddedArchitecture #MonolithicDesign #PezoVonEllrichshausen #InhabitedWall #TerracedHouse #SkylightDesign
