Monolithic Rammed Earth Walls Keep This Marfa Ranch House Insulated in the Desert Climate

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

Designed by architect Luigi Rosselli, this 230-meter-long wall is considered the longest rammed earth wall in Australia and potentially the Southern Hemisphere. The design leverages the Earth's natural cooling properties, embedding the homes beneath the rocky red soil to offer protection from the intense heat of the arid climate. This collective housing project, initially conceived as guest houses for a century-old family cattle station, demonstrates the effectiveness and aesthetic appeal of earth-sheltered architecture. It was recognized as a finalist in the Australian Institute of Architects Western Australia architecture awards and won "best housing project" in ArchDaily's Building of the Year contest in 2016. The residences are accented by Cor-Ten steel canopies and are stepped to ensure privacy, with only their verandahs visible from the exterior. These awnings are strategically placed to prevent direct sunlight from entering the interiors through the glass doors. The complex also includes an oval chapel, positioned on an artificial dune overlooking the family cemetery, with its roof matching the Cor-Ten steel canopies of the residences. The back of each guest house leads to a communal meeting area and lounge, featuring a pergola constructed from old drilling pipes. The chapel, drawing inspiration from the Pantheon of Rome, is oriented eastward and includes a glass-covered oculus. Its curved glass windows can be opened to the elements or closed to protect against dust storms. The firm highlights that the 450-mm thick rammed earth facade and the sand dune covering the rear and roofs of the residences provide exceptional thermal mass. This design makes the homes naturally cool in the subtropical environment, offering a significant improvement over traditional corrugated metal shelters commonly found in remote North Western Australia. The construction materials, including rammed earth sourced from local clay pans and pebbles and gravel from the river bed, integrate seamlessly with the natural landscape. The interiors, designed by Sarah Foletta, feature a restrained, natural, and robust selection of materials and furniture, contributing to a comfortable living space naturally cooled by the earth walls and the meter-deep sand hill. The rammed earth construction process involves filling a framework with damp earth and compressing it, resulting in a strong, naturally pigmented, and beautifully striated wall. While rammed earth alone may not offer optimal thermal performance, its combination with earth-sheltering creates a sustainable solution that utilizes abundant local resources and minimizes the need for mechanical heating and cooling systems, showcasing an innovative approach to remote Australian architecture. #RammedEarthArchitecture #EarthShelteredHomes #SustainableDesign #AustralianArchitecture #LuigiRosselli #PilbaraRegion #EcoFriendlyHomes #ThermalMass #CorTenSteel

The Ranch Mine, a US architectural studio based in Phoenix, has completed a holiday home called Noir Peaks in Flagstaff, northern Arizona. The house is characterized by its black, gabled forms that appear to 'burst vertically from the ground,' reflecting the surrounding volcanic landscape. The location of the property on a grassy, high-altitude plateau in Flagstaff, an area known for its mountains, aspen stands, pine forests, and a vast volcanic field, heavily influenced the design and materiality of the vacation home. The last volcanic eruption in this region occurred approximately 1,000 years ago, leaving a distinctive geological footprint. The Noir Peaks house is built on a two-acre (0.8-hectare) site and consists of a cluster of gabled forms perched on a two-foot-high concrete base. The architectural concept specifically aimed to mimic the volcanic mountains that dot the plateau, with three prominent gabled structures rising vertically. The exterior of the home features fibre-cement, board-and-batten siding, which is painted to match the dark lava rocks prevalent on the site. The spacing of the battens is intentionally varied to evoke the organic and scattered arrangement of nearby aspen trees, contributing to a seamless integration with the natural environment. The design team emphasized the economic construction of the house, stating their goal was to utilize a simple, cost-effective material that could withstand the harsh environmental conditions while achieving an elevated aesthetic through a unique batten pattern. Spanning 2,405 square feet (223 square meters), the interior layout of Noir Peaks is meticulously planned to optimize views of the majestic San Francisco Peaks. The house encompasses multiple communal spaces, a primary suite, three additional bedrooms, a mudroom, a laundry room, and a generously sized garage. The interior design adopts a neutral colour palette complemented by earthy materials such as wood and stone, fostering a warm and inviting atmosphere. For instance, tongue-and-groove hemlock clads the ceilings in the great room and the primary bedroom, adding textural richness and natural beauty. Fireplaces throughout the home are faced with Texas Crème limestone, further enhancing the natural and refined aesthetic. The overall interior ambiance is designed to be cozy and restful, drawing inspiration from the Danish concept of 'hygge.' This philosophy emphasizes creating a comforting and convivial environment that promotes well-being and contentment. In line with this, the designers aimed for the home to serve as a refuge where occupants can recover, rest, reflect, and re-energize in preparation for future adventures. To enhance comfort during the colder months, radiant heated concrete floors are installed throughout the house, providing a consistently warm and pleasant daily sensation. The Ranch Mine has a history of developing projects in Arizona, including a minimalist house in Paradise Valley and a series of townhomes in Phoenix featuring brick, stucco, and weathering steel facades. #VolcanicTerrain #GabledForms #HolidayHome #ArizonaArchitecture #TheRanchMine #SustainableDesign #HyggeInterior #EarthyMaterials #ModernArchitecture

CRU! architects, a Sao Paulo-based architecture firm, completed the Guesthouse Paraty, an eco-conscious social building project that aimed to minimize environmental impact and provide employment and training opportunities for the local community.

In Arizona's San Rafael Valley, the architectural firm DUST has completed "Casa Caldera," an off-grid dwelling designed to harmonize with the unique historical and environmental context of the region. This area, located 15 miles north of the U.S.-Mexico border, is characterized by its volcanic origins, which have resulted in mineral-rich land and a storied history influenced by various cultures and historical events. The design of Casa Caldera directly responds to these influences, emphasizing sustainability and integration with the landscape. The dwelling's construction material, scoria—a porous, lightweight red volcanic aggregate—is integral to its design and performance. This basaltic lava was mixed into a semi-fluid state and pressed into formwork, a technique similar to rammed earth construction, allowing the walls to be self-supporting. This choice of material not only provides excellent thermal insulation due to its 18-inch thickness but also ensures the structure visually blends into its volcanic surroundings. The 880-square-foot home's layout is informed by local architectural typologies, specifically the "zaguan," a central hallway or passage. This design choice addresses the clients' request for both outdoor living and sleeping zones, organizing the interior space efficiently. The house features a rectangular plan divided into three zones: living accommodations and sleeping quarters flank the central zaguan. Large folding metal doors at both ends of the zaguan allow the covered living space to open up to the surrounding landscape, promoting natural light and cross-ventilation. When closed, these partitions offer security and protection. This flexible design allows the central volume to serve multiple functions, from lounging and dining to an additional sleeping area. The zaguan functions as a transitional space, allowing occupants to engage with the natural environment, observe the passage of time, and experience the changing climatic conditions. Heating within the dwelling is provided solely by a wood-burning stove and a fireplace, maintaining the off-grid ethos. Cooling relies on the natural thermal mass of the thick scoria walls and passive airflow, which is managed through strategically placed external operable windows. These windows are intentionally small to minimize direct solar heat gain during the hot summer months, reflecting a careful consideration of solar orientation to optimize indoor comfort without reliance on active cooling systems. Casa Caldera is a testament to custom craftsmanship, with DUST undertaking the fabrication and installation of nearly all components, including the walls, windows, hardware, leather pulls, wood siding, millwork, casework, and framing. This comprehensive approach ensures a cohesive and deeply integrated design. For its utility needs, the dwelling is self-sufficient: an existing well provides water, and a small solar electrical system, situated away from the main house, supplies basic electrical power. Cooking, water heating, and refrigeration are powered by propane gas, further reducing the home’s environmental footprint and reliance on external infrastructure. Completed in December 2015, Casa Caldera represents a harmonious blend of traditional building methods, sustainable practices, and a deep respect for its unique desert environment. #OffGridLiving #SustainableArchitecture #VolcanicRock #ArizonaDesign #DUSTArchitects #CustomBuild #PassiveCooling #Zaguan #DesertArchitecture

In the mountainous region of Bavaria, Germany, a distinctive holiday home known as Haus P offers a contemporary reinterpretation of the traditional chalet. Designed by Stuttgart-based Yonder — Architektur und Design, this 2,680-square-foot residence serves as a rural retreat for a family of seven from Hamburg. The architects, Benedikt Bosch and Katja Knaus, drew inspiration from classic Allgäu chalet-style homes, adapting the form into a modern, sculptural structure. The house is strategically positioned on a gentle slope in the German alpine region of Allgäu. Its exterior features charred wooden siding, which not only provides a natural, weathered appearance but also offers eco-friendly weather protection, contributing to a cool, dark-grey aesthetic. This charred wood contrasts effectively with core-insulated exposed concrete used for the foundations of the basement level, establishing a solid plinth for the timber structure above. The combination of these materials creates a two-toned facade that is both visually striking and functionally robust. The unique geometry of Haus P is a result of maximizing the property’s allowable building envelope. Bosch explains that the design conceptually originates from a classic chalet form with a shallow gabled roof and a full lower level, from which an oblique section was strategically removed along its central axis. This incision effectively divides a single building into two primary components: the main house and a separate storage shed, creating a protected courtyard in the intervening space for outdoor activities. Access to the main entrance is provided by cantilevering stairs along the slanted rear façade, leading to this courtyard. The interior spaces are characterized by their cool, lofty ambiance and an emphasis on pure and simple aesthetics. Wood, a prevalent building material in the region, is extensively used for the home's structural framework and interior finishes. The double-height ground level accommodates the open-plan communal areas, including the kitchen, living, and dining spaces. A large picture window in this area frames stunning views of the surrounding mountains, integrating the natural landscape into the living experience. A modern, minimalistic concrete fireplace is a focal point in the living area. The lower level, or garden basement, is functional and well-appointed, housing two guest rooms, a sauna, and a bathroom, offering practical amenities for a large family or guests. Stairs within the house beautifully blend with the wooden walls, floors, and ceilings, creating a cohesive design. A built-in bench along the stairs provides a quiet spot for reflection, while an upper-level loft serves as an idyllic space for reading or stargazing through its picture windows. The canted shape of the building contributes to these commodious interior spaces with high ceilings, enhancing the overall sense of openness and light within the home. #ChaletInspiredHome #ModernArchitecture #GermanAlps #CharredWoodSiding #ConcreteDesign #HolidayHome #SustainableDesign #ArchitecturalInnovation

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 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

PPAA, a Mexico City-based architectural studio, has completed a guesthouse project for the Danish homeware brand Vipp in Todos Santos, a town located on Mexico's Baja California peninsula. The project marks Vipp's expansion into the hospitality sector. The design emphasizes a harmonious integration with the desert landscape, utilizing pale rammed-earth for both its aesthetic qualities and thermal efficiency. The guesthouse's architecture aims to convey a sense of longevity, appearing as if it has always been an integral part of its environment and is designed to evolve gracefully over time. The structural composition of the guesthouse consists of three distinct square volumes: a primary residence and two guest accommodations. These volumes are strategically arranged around a central courtyard, positioned at each corner and staggered to conform to the natural, gentle slope of the site. This careful placement ensures that each space maintains a degree of privacy while remaining connected to the broader landscape. The design creates a balance between providing shelter from the desert climate and embracing natural elements like ventilation, light, and scenic views. Interior spaces are characterized by their openness, extending onto expansive, stepped terraces. Semi-external living and dining areas are thoughtfully protected by the robust rammed-earth walls. The guest bedrooms feature sliding screens made from the woven branches of the Palo de Arco tree, allowing them to open directly onto the central courtyard. This material choice further enhances the natural integration of the structure. Each of the three volumes is topped with an additional terrace, shaded by fabric canopies supported by metal frames. The largest of these rooftop terraces incorporates a circular swimming pool, which is envisioned as a prime viewing platform for contemplation. From this vantage point, the surrounding landscape, encompassing the desert, ocean, and sky, unfolds in a manner that is both vast and intimate. The material palette primarily features the pale-coloured rammed-earth walls, left exposed throughout the structure, complemented by local stone and wood. The guesthouse is furnished with pieces specifically created by Vipp, further enhancing its bespoke character. PPAA, established in 2018, has a portfolio that includes a mass-timber office building in Querétaro, Mexico, and a concrete villa overlooking Lake Zurich in Switzerland, showcasing their diverse architectural capabilities. The photography for the Todos Santos guesthouse project was undertaken by Anders Hviid. #PPAA #RammedEarth #Guesthouse #MexicanArchitecture #SustainableDesign #Vipp #CoastalArchitecture #DesertArchitecture #Terraces

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
