The house acts as a sanctuary for contemplation where nature is centered.  Staggered walls and large openings create protection while framing views and letting the landscape pass through the space. This allows natural light and ventilation while maintaining a close and continuous relationship with the outdoors.

Toronjos is, essentially, architecture that doesn’t dominate. It blends seamlessly with the landscape, enhancing it and becoming a natural extension of it. The building doesn’t seek to stand out, but rather to disappear among the vegetation, water, and earth, embodying a way of living in harmony with the environment.

 

Le Corbusier: Les Maisons Murondins

Les Maisons Murondins is a series of conceptual earthen refugee housing projects proposed by eminent architect Le Corbusier in collaboration with his partner Pierre Jeanneret during the mid-20th century.[1] In the wake of Germany’s invasion of France and Belgium in May of 1940, France was partitioned into three zones: a military zone in the north occupied by Nazi forces, an Italian colony in the East, and the collaborationist Vichy government in the South.[2] This process saw millions displaced as a result of the German invasion, and forced many refugees into abject conditions bereft of housing or sufficient infrastructure.

Respondent to the devastation of the Second World War, Corbusier and Jeanneret began working on a proposal for refugee housing known as Murondins— a combination of the French words for wall (mur) and logs (rondins). Murondins prioritized earth and wood materials and construction techniques, owing to their accessibility and exceptional performance. Earth and logs did not require advanced industrial infrastructure in order to manufacture and assemble, meaning residents were equipped to construct Murondins themselves.[3] Furthermore, walls could either be constructed out of rammed earth, or blocks of earth combined with lime depending on the circumstances. In essence, Murondins sought to use whatever materials were readily accessible, and designed to be built quickly, without special expertise. 

Sketches of the “Murondins” structural system by Le Corbusir, 1940.

This idea did not only operate materially through the use of earth and wood construction, but also formally through the use of long, rectangular walls, and an offset gabled roof— forms that ensured stability, and that those without technical knowledge or experience in construction could produce them. The internal structure of Murondins was proposed to be entirely constructed out of earth, arranged in L-shaped formations to ensure structural stability.

As for the roofs, they were to be made out of logs and waterproofed using sod, plaster, and tar paper. For purposes of ventilation, roofs were also offset, with one side of the gable taller than the other, to accommodate for daylighting and passive ventilation.[4] With this Murondin system, a range of buildings accommodating whatever programs were necessary for life could be constructed for refugees, by refugees using natural and readily available materials. Although this proposal never made it to fruition, Le Corbusier and Pierre Jenneret’s Murondins continues to serve as an instrumental historical proposal for accessible, communal earthen construction.

Quincho Bernarda Community Center

 

Quincho Bernarda Community Center  I  ArchDaily

The Quincho Bernarda Community Center in Taray, Peru, is a 140m² collective space for residents that completes the KUSKA, a set of habitable structures situated in the South American Andean landscape. Designed in 2025 by Taller MACAA and led by architect and photographer Rafael Ortiz Santos, the Cusco-based practice focuses on residential and public architecture rooted in local context. The firm values the preservation of Andean cultural heritage by honoring traditional adobe construction techniques while regenerating existing buildings through sustainable materials and contemporary methods.

La Cabaña Feliciana, Taller MACAA, 2022   I  ArchDaily
Hogar Florencia, Taller MACAA, 2025   I  ArchDaily

The Quincho Bernarda Community Center is part of the firm’s broader regeneration of KUSKA, which also includes the La Cabaña Feliciana and Hogar Florencia, two additional adobe structures that contribute to the revitalization of the village. Through these projects, the firm demonstrates a commitment to community-centered design, material continuity, and the long-term resilience of rural Andean settlements.

Ground Plan   I  ArchDaily

The term “Quincho” originates from an Argentine tradition describing a dedicated space in the home for gathering, eating, and socializing. This project reimagines that tradition through the spatial framework of a basilica, detached from its religious meaning and adapted into a shared domestic environment organized around a central nave, a kitchen, and two outdoor dining terraces.

Locally Sourced Adobe   I    ArchDaily

Across the center, locally sourced red adobe remains the primary material exposed as both structure and surface, expressing its mass, texture, and construction logic. Traditional load-bearing methods are combined with a contemporary spatial approach that highlights the material’s thermal, tactile, and structural strengths, resulting in an environment that feels both solid and inviting.

Exterior of Community Center   I  ArchDaily

The project is arranged around a single main volume covered by a pitched tile roof. A ridge beam, supported by adobe walls and two eucalyptus columns, is positioned off the central axis of the hall, shifting the structural balance of the roof. This displacement creates a clear internal hierarchy while maintaining a free, continuous plan within the structure.

Interior of Community Center   I  ArchDaily
Construction Detail of Interior Stage   I  ArchDaily

The main hall accommodates a lounge, a long communal table, and a bar that connects directly to the kitchen through both a pass-through opening and a door, while a small stage sits slightly below the primary floor level. Stone steps positioned between the hall and stage double as casual seating, allowing the space to shift easily between everyday use and cultural or community.

Section of Main Hall   I  ArchDaily
Community Center Kitchen & Bar   I  ArchDaily

The use of arches replaced conventional lintels to span openings, improving structural performance under seismic conditions, while allowing for more continuous, open interiors. Within the kitchen, the thickness of the adobe walls is used to carve out built-in niches that seamlessly accommodate storage, and the use of curved walls not only introduces a sculptural presence but also shapes movement and reinforces the space’s sense of enclosure and cohesion.

Outdoor Patio of Community Center   I  ArchDaily

The center establishes a strong connection to the Andean terrain, with terraces that extend the interior outward into the landscape. These outdoor platforms are carefully oriented to receive the morning sun, allowing the spaces to warm gradually throughout the day and creating an inviting setting for early gatherings and shared meals. The northwest terrace, partially sheltered and shaped by the natural slope, frames views toward the Andes, reinforcing the building’s relationship to its surrounding geography.

Stained Glass Arched Windows   I  ArchDaily

On the western elevation, panels of stained glass are embedded within the facade to catch the fading light of the afternoon. As the sun sets, these panes diffuse and refract its rays, casting saturated tones across the interior surfaces and enriching the atmosphere with warm blue and yellow colors that compliment the red adobe. Beyond their visual effect, the filtered light works in tandem with the adobe’s thermal mass, allowing the thick walls to absorb and slowly release heat accumulated throughout the day.

Quincho Bernarda Community Center   I  ArchDaily

Ultimately, the Quincho Bernarda Community Center positions locally sourced construction not merely as a matter of economy or sustainability, but by reframing material as a mediator between interior and landscape, dissolving rigid boundaries and allowing climate, topography, and collective life to shape space. In doing so, it suggests that vernacular techniques are not nostalgic gestures, but active cultural frameworks capable of generating contemporary architecture grounded in place, memory, and communal identity.

Solar Adobe: Energy, Ecology, and Earthen Architecture

Solar Adobe: Energy, Ecology, and Earthen Architecture by Albert Narath

Against the backdrop of a global energy crisis, a widespread movement embracing the use of raw earth materials for building construction emerged in the 1970s. A new book, Solar Adobe: Energy, Ecology, and Earthen Architecture by Albert Narath , examines this new wave of architectural experimentation taking place in the United States, detailing how an ancient tradition became a point of convergence for issues of environmentalism, architecture, technology, and Indigenous resistance.

Utilized for centuries by the Pueblo people of the American Southwest and by Spanish colonialists, adobe construction found renewed interest as various groups contended with the troubled legacies of modern architecture and an increasingly urgent need for sustainable design practices. In this period of critical experimentation, design networks that included architects, historians, counterculture communities, government weapons labs, and Indigenous activists all looked to adobe as a means to address pressing environmental and political issues.

Albert Narath charts the unique capacities of adobe construction across a wide range of contexts, consistently troubling simple distinctions between traditional and modern technologies, high design and vernacular architecture. Drawing insightful parallels between architecture, environmentalism, and movements for Indigenous sovereignty, Solar Adobe stresses the importance of considering the history of the built environment in conjunction with architecture’s larger impact on the natural world.

Senj: Afghan Wood Framing Technology

Senj: Afghan Wood Framing Technology. 1’/1.5” scale. Pine, earth, and poplar

Senj (سنج) is a traditional Afghan wood framing technique. It is a lightweight, flexible, and modular system designed to be placed on upper levels of structures within earthquake prone regions of Afghanistan.

Filling of timber parapet frame with mud-bricks. Amin House Restoration, Kabul, Afghanistan 2004-2005. https://www.archnet.org/sites/5585

The frame is constructed with poplar poles on a flat surface and is joined together to create square or rectangular walls. The horizontal poles are around 15-20cm in diameter, and the vertical/diagonal poles around 10-15cm. They are joined by mortise and tenon about 1m apart, where they are then filled with sun-dried bricks, placed at a diagonal relationship between the vertical and diagonal poles.

Drawings from the book Afghanistan: An Atlas of Indigenous Domestic Architecture p.154

The infilled brick frames are then plastered with a mud and straw mixture on both the interior and the exterior facades. It seems that over time, however, the diagonal poles have been integrated into the complete frame, plastered over and completely hidden. Notice this drawing:

The diagonal bracing pole is left exposed outside of the plaster, as seen in these photos:

Here on the left side wall, all poles have been plastered over and no remnants of the structure are exposed. Could the strength have increased by having the diagonals be integrated into the frame, rather than existing on the exterior of it?

Amin House Restoration, Kabul, Afghanistan 2004-2005. https://www.archnet.org/sites/5585

In Afghanistan: An Atlas of Indigenous Domestic Architecture, the authors state that diagonal poles are *nailed* at the exterior corners to stabilize the frame, not integrated within the frame itself. It is beautiful to witness the underlying structure with the poplar poles exposed as such in the older buildings, and saddening to see that design decision disappear over time. Even more so it is a shame the patterning that the bricks create are also plastered over and disappear. We wonder how senj technology can be re-contextualized contemporarily to become a textural, aesthetic, modular device while also supplying firm, structural integrity to a design.

Thank you so much to Professor Ronald Rael for opening the doors of knowledge, wisdom, research and discovery of ancestral design within the context of Architecture at UC Berkeley.

Teresa Margolles

 

CONTENT WARNING:  graphic descriptions of art installations and construction. ie sexual violence, murder, blood. 

Teresa Margolles, born in 1963, is an artist from Mexico City. Teresa is considered a conceptual artist, with a focus on the impacts of violence and death, specifically in her home country of Mexico, and Latin America as a whole. 

Bernd Kammerer

In her early adulthood, she went to school and studied to become a forensic pathologist. She then worked in the morgue, and witnessed the ways in which bodies, and the lives lost resulting in these bodies, were unnoticed. The violence of her home and surroundings became the subject of much of her artistic work. Margolles went on to create an artists’ collective named SEMEFO in the 1990s. 

“When I was working with SEMEFO I was very interested in what was happening inside the morgue and the situations that were occurring, let’s say, a few meters outside the morgue, among family members and relatives. But Mexico has changed so violently that it’s no longer possible to describe what’s happening outside from within the morgue. The pain, loss and emptiness are now found in the streets.” Teresa Margolles, 2009. 

Margolles has a pattern of using natural earthen and human materials in her work, such as water, dirt, sand, sweat, blood, fat, and tissue. These materials are used to tell her story through the art pieces and installations, all with a focus on violence, erasure, destruction, and death. 

Recovered Blood, 2009

Recovered Blood, as shown above, was created using the mud-soaked clothes that were used to clean the sites of drug-related murders throughout Mexico.

Mesa y dos bancos, 2013

This table and benches were created using a mixture of concrete and organic material harvested from the grounds of the site of a murder on the Northern Mexico and US border.

Vaporizacion, 2001

This installation was created using the water used to wash corpses in the morgue in Mexico. This water was then dispersed throughout the space using two fog machines.

Joyas, 2007

This piece of jewelry was created with shattered glass fragments sourced by Margolles from a local gunfight in Mexico. She then collaborated with a local jeweler to create a piece of jewelry that resembles one a powerful gang member might wear.

Lote Bravo, 2005

This installation, Lote Bravo, in Mexico consisted of adobe bricks. The bricks were mixed and made out of soil and earth harvested from the site of murders and burials of Mexican women found along the border of the United States and Mexico.  These women were often determined to be sexually assaulted at the site of their death.

Cleaning, 2009.

This exhibit featured an hourly mopping of the floor, however the cleaning liquid that was used contained blood from individuals murdered in Mexico.

Herida, 2010.

This installation consisted of a seam in the wall, filled with human fat which was gathered from corpses of murdered people in Mexico.

Marlene Pista de Baile del club ‘Mona Lisa’, 2016

In addition to conceptual and performance art, Margolles is also a photographer. In this particular collection, she focuses on the destruction of clubs in Juarez and throughout Mexico. In the image above, Margolles captures Marlene, a transgender woman standing on what remained of the dance floor of the club she worked at, Mona Lisa.

Above is an example of her recent work, this installation is in London.

It is “a tribute to the resilience of the global trans community,”

Composed of 726 plaster face castings, they were created from the faces of only trans, nonbinary, and gender nonconforming individuals from both Mexico and the United Kingdom.

 

“The works of Teresa Margolles are saddening and at the same time, by virtue of their beauty, captivating. In many instances they evade any attempt at rational explanation by forcing the spectator into virtually physical contact with anonymous corpses. ”

The Poet of the Adobe

Haydar Yaghma, a humble yet prolific Iranian Poet, carved his legacy not only in verse but in the earth itself. Born into a life of labor, Yaghma spent his days shaping adobe bricks—a traditional craft in Iran’s sunbaked landscapes—while his nights were filled with the spirit of words and ideas. Despite his profession, Yaghma’s poetic talent soared; he composed over 5,000 verses that speak to the beauty of simplicity, the resilience of the working class, and the profound connection between humanity and the land. His verses, grounded in the experiences of everyday life, offer readers a raw and unfiltered view into the soul of a man who, though seemingly bound to the soil, found liberation in poetry. Haydar Yaghma remains an emblem of authenticity and passion in Persian literature, bridging the gap between the hands that labor and the mind that dreams.

Anna Heringer’s METI Handmade School in Bangladesh exemplifies an innovative approach to sustainable architecture, rooted in local materials and traditional building techniques. The school was designed to serve as a community hub for education, demonstrating how effective construction methods can enhance both functionality and environmental stewardship.

Floor Plan, Source

The building features two contrasting levels: the ground floor, with thick earth walls and three classrooms, creates a tactile, intimate atmosphere. Each classroom opens to an organic system of ‘caves’. The upper floor contrasts sharply with its light, open design. Bamboo walls allow sweeping views of the treetops and village pond, while sunlight filters through, casting shadows on the earth floor. Colorful saris hang from the ceiling, adding vibrancy to the space, which is designed for movement and connection to the surrounding natural environment. Together, the two levels balance earthiness with openness, offering both introspective and expansive experiences.

Facade Photo,  Source

The foundation of the building rests on a 50 cm deep brick masonry base, finished with a cement plaster facing. In Bangladesh, bricks are the primary building material, produced from the region’s abundant clayey alluvial sand, as natural stone is scarce. These bricks are fired in open circular kilns using imported coal, resulting in a durable and locally sourced construction element.

Construction Photo, Source

An essential addition to local earthen building practices is the damp proof course, consisting of a double layer of locally available polyethylene film. This innovation protects the structure from moisture, enhancing its longevity. The ground floor features load-bearing walls constructed using a technique akin to cob walling. A mixture of straw and earth, with minimal straw content, is prepared with the help of local livestock and applied in layers atop the foundation. Each layer is heaped to a height of 65 cm and then trimmed after a few days to maintain uniformity. After allowing for a drying period, successive layers are added, integrating door and window lintels along with a ring beam made of thick bamboo canes.

 

Section, Source

The ceiling of the ground floor employs a triple layer of bamboo canes, with the central layer arranged perpendicularly to provide lateral stabilization. This layer is topped with split bamboo planking and filled with the earthen mixture, mirroring techniques used in European timber-frame constructions.

For the upper storey, a frame construction is utilized, comprising four-layer bamboo beams and vertical and diagonal members arranged at right angles. This design enhances the structural integrity of the building, with the frames at the ends stiffening the overall structure. Additional structural members connect the beams, and wind bracing is incorporated on the upper surface to further strengthen the frame. Supporting the corrugated iron roof are a series of bamboo rafters, which are adjusted in height for optimal runoff, topped with timber paneling.

Through its innovative design and construction techniques, the METI Handmade School not only provides an educational facility but also serves as a model for sustainable building practices. It engages the community, preserves traditional craftsmanship, and utilizes local resources effectively, making it a beacon of environmental and social responsibility in architecture.
