05
Acoustic properties of materials promote a serene meditative environment.

The Arcanic Cabin project is a significant architectural endeavor designed to integrate seamlessly with the natural surroundings of Latvia's forests. This project focuses on creating sustainable, modular living spaces that promote a connection between individuals and the environment, facilitating reflection and relaxation. The cabins function as meditation spaces, encouraging a healthy lifestyle in tune with nature.

The design is characterized by its curved form and use of organic materials, which reduce environmental impact while optimizing structural integrity and aesthetic appeal. Notably, the project embraces local sourcing of materials, with components such as industrial hemp and preserved plywood being used to ensure sustainability and minimal ecological disruption.

Unique Design Approaches

One of the distinctive features of the Arcanic Cabin project is its innovative use of geometry. The arc-shaped envelope maximizes internal space while minimizing the amount of materials needed for construction. This approach not only enhances the cabin’s functionality but also contributes to its durability. The flexible arrangement of the interior layout allows for customization according to occupants’ needs, further setting it apart from conventional designs.

The project also prioritizes high-performance environmental factors, incorporating both passive and active solar design principles. Strategic orientation allows the cabins to capitalize on natural light and heat, reducing energy needs. With an emphasis on acoustic insulation, the cabins provide a tranquil retreat from external noise, reinforcing the meditative purpose of the spaces.

Material Choices and Their Impact

Materiality plays a crucial role in the sustainability of the Arcanic Cabins. By utilizing hempcrete for insulation and EPDM roofing, the project ensures high thermal performance while maintaining a low carbon footprint. The preserved plywood contributes to durability and local sourcing, supporting the regional economy. The careful selection of these materials enhances the aesthetic quality of the cabins, merging functionality with an organic, natural appearance that integrates well with the landscape.

Overall, the Arcanic Cabin project exemplifies a thoughtful architectural response to contemporary living challenges. It offers an innovative blend of design, sustainability, and functionality, aimed at fostering a lifestyle that respects both the individual and the environment.

To gain a deeper understanding of the architectural plans, architectural sections, and architectural designs associated with the Arcanic Cabin, further exploration of the project presentation is encouraged. The unique architectural ideas embedded in this project can provide valuable insights for both practitioners and enthusiasts of sustainable architecture.

`
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.
