Curved concrete structures combined with sustainable wood elements create a tranquil environment for yoga and meditation in the Portuguese countryside.
5 key facts about this project
01
Curved form mimics the natural landscape for a cohesive visual experience.
02
Four unique zen gardens enhance relaxation and mindfulness throughout the retreat.
03
Extensive use of glass maximizes natural light and views of the surrounding valley.
04
Rainwater collection and biological filtration systems support sustainable practices.
05
Endemic wood sourced locally adds warmth and reduces environmental impact.

The Yoga House Shikhara is located in the scenic Vale de Moses in the Portuguese countryside. It serves as a retreat for yoga and meditation, focused on creating a calm atmosphere that connects its users to the surrounding landscape. The design emphasizes harmony with nature, encouraging a deep interaction between the built environment and the natural world.

Spatial Organization

The building has two levels, each serving different purposes. The lower level includes communal spaces like a kitchenette, dining area, showers, and toilets. These spaces are designed for socializing and shared experiences among users. The upper level features the shala, the main yoga area, which offers ample room and large windows for views of the landscape. This arrangement allows practitioners to feel immersed in the environment while practicing.

Materiality and Structure

Materials are thoughtfully chosen for their aesthetic and functional qualities. The structure uses concrete, glass, and wood. Glass curtain walls in the shala offer plenty of natural light and views, enhancing the feeling of openness inside. Wood elements, sourced from local suppliers, add warmth and character. The concrete serves as a durable foundation, giving the structure its stability and shape.

Landscape Integration

Zen gardens are a key feature of the design, located at various points throughout the property. These gardens create peaceful spots for relaxation and mindfulness. Each of the four gardens is designed uniquely to support different experiences, reinforcing the connection between the building and its natural surroundings. This focus on landscape integration fosters an atmosphere of tranquility.

Sustainability Features

The design also includes features that promote environmental responsibility. A rainwater collection system captures water for various uses, and a septic tank with a biological filter allows for water recycling in toilets. These systems minimize the ecological footprint of the retreat and reflect a growing trend towards sustainability in architectural practices.

The form of the Shikhara gently follows the contours of the surrounding hills, inviting users to engage with the landscape. This design choice encourages a continuous relationship between nature and the built environment. The result is a space that fosters reflection, connection, and tranquility.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
