The project 1/2 Footprint 2/1 Comfort takes a user-perspective on circularity. A group that is mostly unknown with this environmental topic, but nevertheless an important link in the chain of circularity, With the circular solution of a Modular infill system, residents are invited to not only design, but also asssemble, disassemble and reassemble the infill system. In this way, circular solutions become part of the intrinsic motivation of residents. The requirements the infill system should comply with to be user-friendly for non-experienced builders was explored during the research. Next to this, the project gives an answer to the currently imbalance of prices on the housing market by questioning and exploring a new balance of space to own and space to use. It does that by the double use of furniture integrated in the Modular infill system and even more by encouraging residents to enjoy the qualities of all building blocks in the ensemble by the introduction of a collective body. A body that flows through the different blocks, touching upon defined places and spaces open for various activities, Next to this, the project embedds itself by sharing its qualities with the people around and nature through its materialisation, the use of small architectural components, the program of the plinth and use of the surrounding qualities.
