This project is a private vacation space that also serves as a guesthouse. The site is located on a mountainside and takes the form of a rectangular shape, measuring 35 meters in length and 14 meters in width, with a 45-degree rotation relative to true north and south. Following Chinese traditional customs, the site is enclosed to create a courtyard, providing a sense of belonging and security. Each functional room faces true north and south, breaking away from the conventional layout of a large courtyard and creating a loose arrangement where indoor squares and outdoor triangles intertwine.
