The Vrikshasana Hut sits in the scenic Serra da Estrella mountains of central Portugal, serving as part of the Vale de Moses yoga center. It is designed to emphasize nature, balance, and mindfulness, which are essential themes in yoga practice. The name "Vrikshasana," meaning "The Tree Pose," reflects the connection to the environment. The project aims to harmonize human habitation with its natural surroundings.

Design Concept

The hut covers an area of 39 m², providing a flexible arrangement that meets the needs for sleeping and storage. The design prioritizes function while creating a calm atmosphere. By encouraging interaction between indoor and outdoor spaces, the structure enhances the experience of living in harmony with nature.

Site Integration

Located on slopes with a gradient of at least 25 degrees, the hut takes advantage of its surroundings. The use of vertical reed beds helps to filter gray water while promoting the health of the local ecosystem. This approach demonstrates a commitment to sustainable practices, balancing the requirements of habitation with the preservation of the environment.

Material Selection

A specific selection of materials is used in the project, including pine bark, porcelain tile, and sheep's wool. Pine bark serves as a natural exterior layer, connecting the structure to its environment. The porcelain tile provides durability for various surfaces, while sheep's wool serves as insulation, improving energy efficiency and comfort in different weather conditions.

Architectural Detail

The design is marked by simplicity and quiet elegance, allowing it to blend into the landscape without disrupting it. Elevated above the ground, the hut resembles the canopies of trees, enhancing its natural appeal. Each detail is considered to create a space that promotes relaxation and a deep connection with the vibrant surroundings.

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.
