5 key facts about this project
01
The roof design mimics the form of an inverted butterfly to enhance solar energy capture.
02
Cross-laminated timber serves as the primary structural support, ensuring a lightweight build.
03
Rainwater harvesting systems integrated into the design manage local water resources efficiently.
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.

Competition organisers

The Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
