Elevated Concrete and Steel Structure with Modular Expansion for Sustainable Housing

Project in-detail

Elevated above potential flooding, the concrete and steel structure offers modular living spaces designed for adaptability and sustainability within Nairobi's urban landscape.
5 key facts about this project
01
Elevated design enhances airflow and flood resilience.
02
Modular construction allows for incremental expansion by residents.
03
Use of durable concrete and galvanized steel maximizes structural integrity.
04
Incorporates natural light through strategically placed glass elements.
05
Outdoor terraces create communal spaces for social interaction.
The Haba na Haba House is an architectural project located in the informal settlement of Kibera, Nairobi, designed to address the necessity for sustainable and adaptable housing solutions. This project encompasses a modular structure that supports incremental growth according to the needs of its residents. With urbanization impacting housing availability and quality, this design presents a viable solution tailored to the unique challenges faced by densely populated regions.

The Haba na Haba House offers a multi-functional living environment, integrating both private and communal spaces. It features flexible room layouts and open-plan living areas that encourage social interaction while allowing for individual privacy. The building is elevated to combat potential flooding and promote airflow, enhancing the overall livability of the space.

Sustainability plays a central role in the design, with careful consideration of materials and energy efficiency. The use of concrete for structural elements ensures durability, while galvanized steel contributes strength to various features such as staircases and railings. Interior elements utilize wood, providing warmth and texture, and glass is incorporated to maximize natural light and connect interior spaces with the exterior environment. Insulation materials enhance thermal efficiency, and a waterproof membrane guards against moisture-related concerns.

An essential aspect of the Haba na Haba House is its unique modular design, which enables families to expand their living space gradually. This flexibility allows residents to adapt the home as their needs evolve, encouraging long-term use and creating a resilient housing model. The architectural approach prioritizes sustainable practices, integrating renewable energy sources and green roofing systems that further enhance environmental sustainability.

The project stands out through its emphasis on community engagement and outdoor integration. By incorporating terraces and gardens, it fosters interaction among residents and promotes a connection to nature, an often overlooked aspect in urban settings. The architectural design is not only a response to the immediate housing crisis but also a broader commentary on urban living’s potential for adaptability in informal settlements.

To gain deeper insights into the architectural plans, sections, designs, and unique ideas underpinning the Haba na Haba House, readers are encouraged to explore the project's detailed presentation. This project serves as a model for future housing strategies in similar urban environments, reflecting a mindful approach to architecture that balances functionality, sustainability, and community well-being.
