03
Incorporates recycled textile insulation made from denim and sweaters.
04

The Smart Compostable and Reclaimed Microhome is located in temperate areas on the edges of urban environments, where it addresses the need for affordable housing among young professionals. The design focuses on compact living, emphasizing functionality and minimalism to meet essential needs. The goal is to create a living space that not only looks modern but also supports a more sustainable way of life. This approach offers a fresh solution to the ongoing challenges in urban housing.

Materiality

The project uses a range of materials that promote both comfort and sustainability. Straw acts as thatch for the building envelope, providing a biodegradable and recyclable option. It offers excellent insulation, helping to keep energy costs low while minimizing environmental impact.

Reclaimed timber serves as the structural framework, particularly using reclaimed engineered Robinson oak. This material choice supports resource conservation and significantly reduces the carbon footprint associated with sourcing new timber, reinforcing the commitment to environmental care.

Recycled textile insulation, made from leftover denim and sweaters, reflects a sustainable reuse strategy. It enhances thermal performance while keeping waste from entering landfills. This innovative choice in materials contributes positively to the building's overall ecological impact.

Innovative technology

The design incorporates photovoltaic solar glass, enabling the microhome to generate energy while allowing plenty of natural light inside. This feature keeps living spaces bright and inviting, while also allowing residents to be more energy independent. It creates a strong relationship between indoor and outdoor areas, enhancing the overall living experience.



With a modular approach, the microhome can adjust to various site conditions. This flexibility allows for customization that fits into the local environment. Effective space utilization and access to natural light contribute to a peaceful and pleasant living atmosphere.

`
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.
