In response to the problem of packed and dense urban spaces that the residents of Japan often find themselves caught in between, local Japanese architect and design studio Yuko Nagayama & Associates have constructed building called Katsutadai House in the city of Chiba, Japan. This isn’t just a regular residence though -- it is actually a dual space that features the ground floor for commercial purposes and the top floor for residential purposes.
At the ground level, a pastry shop occupies the space, fitted with an angled glass ceiling that allows natural light to flow into the pastry shop. Behind the shop, the entrance to the residence can be accessed via a side door. there is a physical air partition that separates the two spaces -- home versus shop. The residence occupies the second and third floors.
