**Project Overview**

Located within the Efua Sutherland Children’s Park in Accra, Ghana, the Ntonan Houses project aims to address urban housing challenges while integrating local cultural elements and sustainable practices. The initiative responds to pressing issues such as flooding and water scarcity by providing off-grid modular dwellings designed to enhance community resilience and accommodate various demographics, with a focus on vulnerable populations, including street children.

**Cultural and Environmental Integration**

The design is anchored in the symbolism of **Ananse Ntontan**, which represents wisdom and the interconnectedness of life within Akan culture. This cultural reference informs the layout and communal objectives of the project, promoting relationships between residents and the environment. The architectural approach emphasizes flexibility through modular living, allowing for adaptable housing solutions. Sustainable building practices are central to the project, with a vocabulary that incorporates eco-friendly resources and encourages local engagement in construction processes.

**Material and Spatial Composition**

The Ntonan Houses utilize bamboo, sustainably sourced wood, and recycled materials to achieve structural integrity and aesthetic appeal while minimizing environmental impact. The use of solar panels within the design facilitates energy autonomy for the residents. Architecturally, the structures feature curvilinear forms that resonate with local vernacular aesthetics, elevated on stilts to mitigate flooding risks.

The spatial organization emphasizes interconnected units that foster communal interaction through shared spaces. Design elements such as common areas for collaboration and private sanctuaries balance communal living with individual privacy. Curved pathways link the houses, encouraging movement and social interaction while preserving the natural landscape.

`
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.
