04
Large glass panels provide unobstructed views, merging interior spaces with the surrounding nature.
05
The building elevation minimizes ground disturbance, preserving the natural landscape.

The Yoga House on a Cliff is located in Vale de Moses, designed to offer a peaceful environment for wellness activities. It blends with the natural surroundings, showing a focus on reducing environmental impact. The design centers on creating a connection between the building and the forest. Organic shapes represent natural forms, making this structure a retreat that encourages a deeper relationship with nature.

Structure and Form

The roof design draws inspiration from traditional rural architecture in Portugal, adopting an abstract form that fits into the landscape. Elevated above the ground, the building has a low profile, allowing it to sit unobtrusively among the trees. This height not only reduces the footprint but also enhances views from the interior. The layout of spaces promotes engagement with the environment, particularly in the yoga room, which opens fully to the forest.

Material Selection

The main structural element is cross-laminated timber (CLT), which provides both lightness and strength. This choice helps in efficient building while keeping the structure secure in its natural setting. Stone is also used in various parts of the design, offering stability and a sense of permanence. Large glass panels invite ample light and connect indoor spaces with the outside world, fostering a sense of openness.

Sustainability Measures

Sustainability is an important aspect of the design, featuring a green roof that captures rainwater for reuse. This roof has an inverted butterfly shape, which not only enhances aesthetics but also supports solar panels for improved energy efficiency. Such features illustrate a commitment to protecting the environment, making resource management practical and effective.

Interior Experience

The arrangement allows for smooth movement between different areas, including yoga spaces, service rooms, and quiet corners. Transitions from one space to another encourage reflection and thoughtful engagement with nature. The expansive glass openings throughout the building strengthen this connection, as they provide breathtaking views and allow nature to flow into the interior.

The roof’s gentle curves mimic the landscape, offering shelter while contributing to a sense of calm and connection to the environment.

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.
