Constructed with rammed earth and defined by a circular oculus, the design provides a contemplative space for meditation and community gatherings, seamlessly integrating with the surrounding landscape.
5 key facts about this project
01
Rammed earth walls enhance thermal efficiency and integrate with the site’s geology.
02
The circular oculus at the apex allows natural light to filter into the interior space.
03
Cross-laminated timber framing provides structural stability while supporting large spans.
04
A communal firepit is centrally located, fostering social interaction among users.
05
The design minimizes disruption to local tree canopies, preserving the existing ecosystem.

The Kawa Burdei is an architectural initiative that showcases a careful approach to design. Set within a natural landscape, the space serves as a place for reflection and community interactions. The design centers on capturing the Present Moment, using proportions that relate to both the human body and the environment.

Building Layout

The layout features a long, sloping pathway that leads down into a carved Earth basin, which creates a strong connection to the landscape. By avoiding disruption to the existing tree canopies, the design improves energy efficiency by utilizing the thermal qualities of the Earth. This sunken form encourages occupants to engage with their surroundings in a direct way.

Spatial Configuration

Inside, the Kawa Burdei offers spaces that promote both individual contemplation and social connection. There is ample room for yoga practices and quiet relaxation. A secondary area around a ritual firepit includes seating for six, allowing for communal gatherings. A shallow stair adds versatility, providing extra seating for larger groups or classes.

Material Characteristics

The materials chosen for the project play an important role in its overall effectiveness. The floor and walls of the basin are made of rammed earth, with an admixture that includes less than 10% concrete. This choice enhances the connection to the ground while reflecting the unique geology of the site. Cross-laminated timber framing defines the canopy, ensuring stability while also allowing light to enter through a circular oculus.

Tactile Integration

The roof is covered with shake shingles sourced from local trees, which deepens the building's link to its surroundings. This decision supports sustainable practices while adding a hands-on quality to the exterior. Each element of Kawa Burdei contributes to a welcoming experience, leading occupants to engage with the natural world 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.
