The Cube House, located in Bulgaria, showcases a modern approach to compact living. Designed for those seeking a sustainable lifestyle, it offers a minimal footprint while providing essential living spaces. The concept challenges the idea that larger homes are necessary for comfort and functionality.

Design Concept

The structure features a simple cube form that maximizes space efficiency. It encompasses a bedroom, kitchen, bathroom, and workspace within its compact size of 25 m². The house rests on a platform-like foundation that minimizes the impact on the surrounding terrain. This design allows for easy transportation, accommodating users who may require mobility in their housing arrangements.

Functionality and Adaptability

Inside, the layout emphasizes practicality through smart furniture solutions designed to enhance adaptability. Spaces can change to meet the varying needs of the inhabitants, allowing for a fluid living experience. This approach ensures comfort without sacrificing the overall utility of the compact design.

Sustainability and Technology

Energy independence is a key focus of the Cube House. Technologies such as composting toilets, solar panels, and biogas systems are seamlessly integrated, enabling self-sufficiency. The inclusion of rainwater collection systems further promotes sustainable living by utilizing natural resources.

Materiality

The Cube House employs wood, glass, and thermo-panels to create a lightweight, durable structure. These materials contribute to a modern aesthetic that aligns with the minimalist philosophy. The extensive use of glass facilitates natural light, making the interior feel open and inviting while reducing the need for artificial lighting.

The combination of a simple cube shape with multifunctional design highlights a commitment to ecological awareness and contemporary living needs. Each element of the house works together to create a practical yet comfortable environment.

`
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.
