KUBANTU addresses the considerable housing challenges faced in South Africa, especially for low-income communities. Located in an area where housing shortages are prevalent, the design emphasizes adaptability and community. The concept focuses on creating homes that not only provide shelter but also promote individual and communal growth. Each residence is crafted with the intent of enhancing the quality of life for its occupants while fostering economic opportunities.

Sustainability and Resource Efficiency

Sustainability is a core feature of KUBANTU's design. Each home includes solar panels that allow residents to access electricity, even during outages. This aligns with a broader focus on renewable energy. Rainwater harvesting systems are another integral part of the design. Tanks collect and filter rainwater, ensuring a reliable water supply for everyday use and encouraging urban farming within the community.



Adaptable Living Spaces

The layout of each house is designed to fit the diverse roles of its residents. Areas are specifically allocated for living, cooking, gardening, and conducting business. This thoughtful division not only supports individual economic activity but creates an environment where community members can thrive together. The result is a living space that is functional and promotes interaction among residents.



Material Selection and Aesthetic Considerations

Material choices for KUBANTU reflect its practical and aesthetic goals. Aluminum framed windows provide security and durability, while steel IBR sheeting forms the main structure. Steel burglar bars offer additional protection, and perforated walls improve airflow throughout the homes. The use of semi-clear polycarbonate sheeting, inspired by Esther Mahlangu's artwork, adds a unique visual element to the roofs. This choice enhances both the appearance and the identity of the community.



Integrating Nature and Community

KUBANTU intentionally connects homes to nature. Unlike many traditional housing projects, these residences include private gardens and outdoor spaces. Such features improve residents' interactions with their environment and enhance overall well-being. Each home not only caters to individual needs but also encourages community involvement and shared responsibility for the landscape, promoting a sense of belonging among residents.



The design supports both living and working, creating areas that allow for skills development and trade. It balances the needs of individuals with the shared aspirations of the community. This thoughtful arrangement strengthens the neighborhood and helps create a more vibrant living experience for all.
