Continuous footbridge connects cabins without defined entry points, encouraging exploration.

Casa Engawa is an architectural retreat situated in the calm surroundings of Vale de Moses, Portugal. It is designed to support meditation and reflection, drawing inspiration from the Japanese concept of "Engawa." The cabins aim to create a deep sense of connection between users and the natural world, emphasizing the relationship between the built environment and its setting.

Conceptual Framework

The design includes four meditation cabins connected by a footbridge. This layout encourages exploration. Users travel along an open path rather than entering through a defined entrance. The design enhances the experience of nature and promotes an interactive relationship with the environment. By allowing for movement through various spaces, the cabins invite users to engage more fully with their surroundings.

Material Selection

Each cabin is wrapped in a grated steel skin. This design choice allows local plants to grow and intermingle with the structure. It also emphasizes the connection with the landscape. The cabins feature charred timber on the outside, known for its durability and weather resistance. Inside, the plywood finish creates a warm and inviting atmosphere, deepening the sensory experience within each cabin.

Architectural Dynamics

Casa Engawa draws on elements of the Japanese Engawa by focusing on organization, space, and thresholds like steps and landings. The design reinterprets traditional ideas, creating longer thresholds that soften the divide between indoor and outdoor areas. This encourages users to move freely, enhancing their sense of meditation and relaxation while connecting with nature.

Sustainable Integration

The cabins are supported by point foundations, which allow them to adapt to different ground conditions. This design approach reduces environmental impact. Elevated floors enable the use of rainwater collection systems, further promoting sustainability.

The careful connection between the architecture and the landscape forms an atmosphere conducive to contemplation. The sound of leaves in the wind blends naturally with the sight of surrounding greenery, enriching the experience for users.

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.
