The project located in Nima, Accra, aims to tackle the pressing challenges posed by rapid urbanization and a lack of adequate housing in a district characterized by informal settlements and abandoned structures.

The initiative introduces innovative micro-community designs that repurpose underutilized buildings, ultimately working to create a more cohesive urban environment. This approach is not just about aesthetics; it focuses on the design principles, material choices, and distinctive features that enhance the project’s significance within the urban fabric of Accra.

Spatial Design and Functional Integration

Central to the design is the creation of vibrant communal spaces, transforming vacant lots and uninhabitable buildings into multifunctional environments. This strategy is driven by a commitment to sustainability and resilience, evident in the layout where clusters of micro-units surround central communal areas that encourage social interaction. The spaces cater to diverse uses, including living quarters, public areas, and zones for agricultural practices, reinforcing community ties.

Moreover, the integration of ecological systems is crucial in this setting. Buildings are envisioned as "productive envelopes," featuring green roofs and vertical gardens to strengthen the connection between urban residents and nature. Balconies and terraces are specifically designed for urban gardening, promoting community engagement in food production and helping to address local food security challenges.

Sustainability and Materials

In terms of materials, the project makes thoughtful choices to ensure sustainability and local relevance. Key components include lightweight bamboo wall panels that minimize the carbon footprint, recyclable polycarbonate panels providing thermal insulation and natural light, durable recycled steel frameworks, cost-effective plywood flooring, solar photovoltaic panels for renewable energy harnessing, and efficient water harvesting systems for rainwater collection.

Overall, this initiative distinguishes itself through its dedication to revitalizing an urban area while addressing critical social and environmental issues. By fostering communal ties and enhancing local economic activities, the project embodies a holistic approach to urban living. Engaging the community through participatory design methods, including diagrams and collaborative planning tools, ensures that the proposed solutions are not only innovative but also deeply relevant to the needs of the local population.

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.
