Cotton Park is a large collection store based in the community, including three functional modules: coffee, clothing retail, and parent-child activity area. We abandoned the design method based on functional zoning, and took a completely homogeneous and abstract space model as the basis of design, allowing an adaptive structural unit to grow on its own. In this way, the experience part of space is formed first: scale, weight, boundary, sense of enclosure, and mobility. The second step is to superimpose the functional area on the system and fine-tune the system to form the final design result.
