The VALE DE MOSES Meditation Cabins, known as CASA ELEMENTARIA, are located in Valle des Moses. The design emphasizes sustainability and a simple approach to construction. The cabins serve as a retreat where visitors can feel connected to the natural surroundings. With a focus on low energy consumption and accessibility, the concept is well-suited for its mountainous environment.

Structural Integrity and Assembly

The building uses cross-laminated timber (CLT) panels that come pre-cut for easy assembly. These panels create a sturdy framework and make on-site construction straightforward. Two chimneys, made of masonry and CLT, anchor the building to concrete pad foundations. This structure adapts well to the terrain while keeping a minimal footprint that blends into the landscape.

Passive Cooling Techniques

The design employs passive cooling methods that draw on traditional practices. Wind catchers help to enhance airflow through the building, using stack and cross ventilation. This approach reduces the need for mechanical cooling systems and promotes a pleasant indoor climate. Such strategies align with the overall goals of energy efficiency and environmental care.

Water Management and Filtration

A key aspect of CASA ELEMENTARIA is the reedbed water filtration system. This system captures rainwater and grey water for reuse, reinforcing the importance of resource management. The chimneys not only provide thermal mass for winter heating but also act as wind catchers in the warmer months. This multifunctionality highlights the design's adaptability to seasonal changes.

Material Selection and Environmental Impact

Choosing materials thoughtfully reflects a commitment to local sourcing and sustainability. The use of masonry and cork for exterior walls contributes to thermal regulation while keeping the building's environmental impact low. These materials are efficient and resonate with the local character, strengthening the connection to the region.

The design allows light to play across spaces, as louvres on the chimneys open to improve ventilation and frame views of the natural surroundings. This detail invites occupants to engage with nature, creating a calm environment that fosters a sense of peace and mindfulness.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
