Timber panels pivot to control sunlight while framing expansive views in a community-focused space designed to encourage interaction and accessibility.
5 key facts about this project
01
Timber panels can pivot to adjust sunlight exposure.
02
The design incorporates a spiral shape for communal interaction.
03
Excavated land allows for unobstructed landscape views.
04
Large bay windows enhance interior-natural connections.
05
A green promenade surrounds the structure, promoting biodiversity.

The TreSpirala project brings together community needs and environmental awareness in a setting that encourages interaction and connection. Located in a picturesque landscape, the design includes three main areas: an event space, a kitchen, and a bathroom. The core concept revolves around a spiral shape, symbolizing continuous development and unity among users. This shape allows for an inviting and practical environment for various social activities.

Design Integration

The foundation of the design is based on a careful excavation that accommodates the interior spaces without blocking surrounding views. This strategy helps integrate the circular forms with the natural environment, making the transition between built and natural spaces smooth. Landscaped ramps promote accessibility, encouraging movement and interaction as people approach the building.

Materials and Sustainability

Sustainability is a key focus of the project, evident in the use of locally sourced timber. This choice reduces transportation impacts and supports local economies. Timber construction also allows for large bay windows that let in ample natural light, enhancing the connection between the interior spaces and the external landscape. The lightness of the timber contributes to a friendly and open atmosphere.

Ecological Features

The retaining wall, made with interlocking wooden cleats, supports gravel and soil while promoting plant growth. This design creates a green boundary that enriches the surrounding area and helps foster biodiversity. The wall serves not only a structural purpose but also enhances the visual connection between the building and nature, providing a more engaging experience for visitors.

Adaptive Sun Control

Large wooden panels are used along the facade to manage sunlight and maintain views of the landscape. These panels pivot on a central axis, allowing users to adjust the light levels according to their preferences. This flexibility increases the functionality of the central event space, adapting throughout the day and maintaining an open and inviting feel.

The TreSpirala project stands out for its ability to connect people with their environment. It encourages community interaction while respecting its natural surroundings, creating a space where both people and nature can thrive in harmony.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
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.
