The integration of Eucalyptus structures and Cork Oak elements creates a tranquil retreat that fosters mindfulness and yoga within its forest setting.
5 key facts about this project
01
Cork Oak serves as a thermal load-bearing structure for the building.
02
Maritime Pine is treated using the Shou Sugi Ban technique for exterior durability.
03
The design features a zen garden, known as Karesanshu, for reflection and serenity.
04
Natural ventilation systems enhance air quality throughout the retreat.
05
Eucalyptus trees collect rainwater through their leaf structure, aiding sustainability.

The House of Trees is located in the forested landscape of Portugal, designed to provide a peaceful escape for those seeking wellness and introspection. The concept focuses on creating an environment that encourages individuals to reconnect with nature while engaging in mindful practices like yoga. Drawing from the Sanskrit word "Shala," the design reflects a space that promotes personal reflection away from daily distractions.

Camouflage in Nature
The design integrates local tree species, establishing a natural dialogue with the surroundings. The structure utilizes Cork Oak, which acts as a thermal load-bearing element, and Maritime Pine for external cladding, treated with the Shou Sugi Ban technique to enhance its longevity. Eucalyptus trees are selected for their unique leaf structures, which aid in water collection. Additionally, the Olive Tree offers environmental benefits and psychological comfort, particularly within the zen garden, known as Karesanshu.

Spatial Configurations
The House of Trees features dynamic spatial arrangements that alternate between open and enclosed areas. These configurations help maximize natural light and ventilation while ensuring user privacy. This thoughtful approach allows individuals to engage with their environment freely. The balance between indoor and outdoor spaces further strengthens the user experience.

Sustainability Principles
Sustainability is a core aspect of the design. Systems for natural ventilation and water reuse reduce consumption and promote efficiency. A heat pump is integrated into the structure to manage temperature changes throughout the seasons. The roof is designed to capture solar energy effectively, meeting both thermal and electrical requirements. Transparent polycarbonate elements allow for abundant natural lighting, providing clear views of the surrounding landscape.

Organic Integration
The House of Trees reflects a careful interaction between built space and its natural context, enhancing the user's relationship with the environment. The use of local materials helps the structure blend with the forest, offering an experience that is both calming and enriching. The design encourages occupants to explore and reflect, fostering a deeper connection with the tranquility around them.

`
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.
