A walkable roof integrates natural insulation and galvanized steel elements in a design that elevates the living space above the landscape, providing a sustainable seasonal cabin experience.
5 key facts about this project
01
A walkable roof design enhances interaction with the natural surroundings while maintaining ecological integrity.
02
Natural insulation is achieved using locally sourced straw and reed materials, reducing environmental impact.
03
Elevated structure allows for wildlife movement beneath, fostering biodiversity on the site.
04
Charred wooden shingles provide durability and a unique aesthetic, referencing traditional building methods.
05
The open-plan interior facilitates flexibility for social gatherings and seasonal changes in usage.

### Overview
The project is situated in Latvia, where the design integrates local cultural heritage with contemporary architectural practices, emphasizing sustainability and adaptability within the natural landscape. Drawing inspiration from traditional Latvian wooden architecture and Icelandic turf houses, the built environment aims to blend functionality with aesthetic considerations, creating a dialogue between past and present.

### Spatial Integration and User Experience
The architectural concept revolves around the theme of a "turf cabin," where the elevated structure facilitates a harmonious coexistence with the surrounding environment. This design choice allows for the free movement of wildlife and vegetation beneath the building, reinforcing the connection between human habitation and nature. The interior layout is characterized by an open-plan arrangement that promotes multifunctionality, accommodating different group sizes and transforming spaces as needed. Large openings invite natural light and views, fostering an engaging atmosphere for inhabitants.

### Material Selection and Sustainability
The project prioritizes the use of locally sourced materials to minimize environmental impact and reduce transportation emissions. Externally, wood serves as the primary structural element, reflecting regional craftsmanship, while galvanized steel is employed for durability and stability. Internally, reclaimed timber is utilized for flooring, and natural insulation materials such as straw and reed enhance thermal comfort. Sustainable technologies, including a multifunctional fireplace for heating water and cooking, illustrate a commitment to modern eco-friendly practices. Additional features such as rainwater harvesting systems contribute to the building’s overall sustainability, while design elements that echo the undulating landscape further integrate the structure into its context.

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.
