With its unique cork façade and foundation supported by ground screws, the design creates a harmonious yoga retreat that emphasizes sustainability and a deep connection to the surrounding pine forest.
5 key facts about this project
01
The building is completely clad in Portuguese cork, enhancing thermal insulation and tactile experience.
02
Ground screws are used for foundation, reducing land disturbance and environmental impact.
03
Extensive use of cross-laminated timber contributes to structural integrity while maintaining a warm aesthetic.
04
Water is sourced from a borehole, with grey water managed for irrigation, promoting resource efficiency.
05
The design features large openings that connect yoga spaces directly to the forest, fostering a natural atmosphere.

Situated in a quiet pine forest, Jardim Coberto serves as a yoga house designed to create a close connection with nature. The space is intended for yoga practitioners seeking tranquility and reflection. Its clear design concept centers on opening up the building to the outside world, encouraging users to feel the presence of the surrounding environment while they practice and relax.

Design Concept

The design emphasizes the relationship between the built environment and the natural landscape. By blending interior and exterior spaces, the layout invites people to experience nature firsthand. This thoughtful organization allows for smooth transitions between different functional areas, encouraging both individual reflection and communal gathering. The layout seeks to enhance well-being by deepening the connection between users and their surroundings.

Materiality

Materials are an important aspect of Jardim Coberto. The use of Portuguese cork wraps the building inside and out, creating a tactile relationship with nature and providing effective insulation. The cork’s warm colors and texture align with the forest environment. Wood is also a key material, with the structure made from cross-laminated timber (CLT), which highlights the commitment to sustainability and ecological design.

Sustainability Features

Sustainable practices are integral to the design. Ground screws serve as the foundation, minimizing ground disturbance while ensuring stability. Energy needs are met with a photovoltaic solar panel system that enables the building to produce its own power. A borehole supplies drinking water, with grey water being redirected for garden irrigation. This thorough approach to water and energy management reflects an effort to minimize environmental impact.

Spatial Experience

Each functional area is designed carefully to maximize natural light and foster a calm atmosphere. The yoga spaces feature large openings that connect directly to the forest, allowing practitioners to feel part of nature. This thoughtful design promotes well-being and introspection. By blending indoor and outdoor environments, Jardim Coberto encourages a profound interaction with the landscape that surrounds it.

With careful attention to detail, such as the incorporation of greenery along the building’s sides, Jardim Coberto illustrates the principles of practical and environmentally sensitive design.

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.
