The Commensal Home project focuses on the pressing need for affordable housing, combining sustainable design with functionality. It is designed to fit well in both urban and rural environments, emphasizing practical solutions while encouraging connections within the community. The overall approach emphasizes efficient use of space, aiming to enhance everyday living without sacrificing quality or comfort.

Energy Efficiency and Sustainability

At the heart of the Commensal Home is its dedication to energy independence. The design includes systems for collecting rainwater and generating solar energy, allowing the home to operate autonomously and reduce dependence on external utilities. Additionally, the handling of wastewater employs phyto-purification methods, utilizing plants in ponds to ensure both environmental sustainability and the appropriate management of resources.

Flexible Living and Commercial Space

The ground floor features a clever design that serves two functions. When the mobile awning is closed, it operates as a living space. When opened, it becomes a space for commercial activities. This adaptability meets modern needs for work-life balance, encouraging residents to engage in small business activities while making the most of every available area.

Materiality and Construction

The structure of the Commensal Home relies on Cross Laminated Timber panels. This choice supports a lightweight, environmentally friendly approach. The prefabrication of these panels streamlines the construction process, making it quicker and more efficient to assemble on-site while minimizing the amount of labor required.

Interior Design and Spatial Organization

Inside, the home is organized around a central service core. Split-level designs enhance the perception of space, creating a dynamic and engaging interior. Each level serves a distinct purpose, allowing movement and activity to flow naturally. The inclusion of a hanging net feature provides additional usable space while maintaining an open feel, supporting the multifunctional intent of the design.
