Designed to address homelessness in urban São Paulo through communal spaces.

Bananeira's House is located in São Paulo, Brazil, and focuses on addressing the pressing issue of homelessness in the area. The design consists of three blocks that serve different functions: social interaction, private living, and infrastructure. This thoughtful arrangement promotes sustainable living and community involvement, aiming to provide practical housing while being mindful of environmental impacts.

Design Concept

The social block includes spaces for cooking and gathering, encouraging connections among residents. The design emphasizes openness, with high ceilings that allow natural light to fill the spaces. In contrast, the private block is dedicated to sleeping and working areas, ensuring that residents have a peaceful and private environment. The careful angles and layout enhance both comfort and efficiency.

Infrastructure and Sustainability

The wet tower incorporates essential facilities, such as a bathroom and solar heating systems. This integration of necessary utilities supports the overall design, making daily living more convenient. A key feature is the "Bananeira Circle," a biofilter system that treats gray water and directs it to an area with banana trees. This design element not only manages waste but also promotes food production, linking practical solutions to environmental stewardship.

Materiality and Innovation

Material choices are a crucial part of the design. Cross-laminated timber (CLT) is used for its durability and carbon-negative properties. Wooden panels, coated with projected cork, serve to waterproof the structure. Translucent tiles made from recycled PET bottles contribute to natural lighting and energy efficiency. Braided banana tree leaves are also included in the roofing, enhancing air circulation and the overall ecological footprint.

Design Detail

Another important aspect of Bananeira's House is the inclusion of community vegetable gardens. These gardens address food security and provide fresh produce for residents. They also create opportunities for collaboration among inhabitants, fostering a sense of community as they work together in cultivating their food.
