Using self-healing concrete panels, the compact housing solution addresses water scarcity through integrated sustainable technologies, paving the way for efficient living spaces in the Black Sea region.
5 key facts about this project
01
Self-healing concrete panels autonomously repair cracks, enhancing structural longevity.
02
Integrated water management systems capture and utilize rainwater efficiently.
03
Compact design promotes multifunctional living in limited space.
04
Modular construction allows for flexible configurations tailored to user needs.
05
Constructed with materials sourced to minimize environmental impact.

The Bio Concrete Module is an innovative response to the pressing issue of water shortages in the Black Sea region of Bulgaria. It integrates compact living solutions that include bathrooms, kitchens, sleeping areas, and workspaces. The design prioritizes efficient use of available space while encouraging sustainable living practices. The overall concept aims to address the challenges posed by climate change in a straightforward manner.

Materials

Precast self-healing concrete panels are a central component of the design. These panels are made up of several layers, including concrete wythes, reinforcement, insulation, and connectors. This multi-layered system enhances the building's structural strength while introducing a self-healing capability. When cracks develop, the concrete can produce limestone to fill these gaps, reducing the need for ongoing maintenance and extending the building’s lifespan.

Water Management System

The project features a thoughtful water-saving system that aims to lessen reliance on external resources. This includes a solar water heating system and clean water pipes, along with two solar electric panels. The design also incorporates a roof designed for collecting rainwater, a main water tank, and various irrigation elements. Together, these systems enable efficient water use and support the sustainable focus of the design.

Geographical Context

Located in an area that faces significant environmental challenges, the Bio Concrete Module is relevant not just for Bulgaria, but also for neighboring countries like Romania, Serbia, Greece, and Turkey. The design takes into account local climate conditions. It seeks to promote resource conservation and respond to the practical needs of the region.

The design balances functionality and aesthetics without complicating the user experience. Practical features, such as the integration of water collection and solar energy systems, combine to create a living environment that meets modern demands. The module offers a useful example of how future residential developments can embrace sustainability while remaining accessible and efficient.

`
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.
