The project is located in Reservoir Village, Caojing Town, Jinshan, where there are 41 large and small rivers and more than 70 islands. The main task of the project design is the renovation of two independent villas on Jiajin Island. The old architectural space has been transformed from two villas into a bed and breakfast and a shared office building. The original intention of the design was to transform the original single living space into a diversified complex space, and we set the project as "COOL".
