庭院是传统庭院生活的核心。房间向内院开放。半透明的传统木门窗不仅解决了室内照明问题，而且给室内提供了一部分隐私，但我们希望每个房间都有隐私和良好的照明，以及改造后的风景如画。因此，本设计在原来的两个大院子里增加了十个小庭院。建筑师将原建筑与庭院的关系调整为建筑、私人庭院和公共庭院之间的关系。每个房间都对私人庭院开放，通过墙壁上的洞，空间变得有趣。一个原始的共享庭院变成了一组共享和私下共存的庭院。

The courtyard is the core of the traditional courtyard life. The room is open to the inner courtyard. The translucent traditional wooden doors and windows not only solve the indoor lighting but also give the interior a part of privacy, but we hopes that each room has privacy and good lighting, and picturesque scenery after the transformation. Therefore, the design has added ten small courtyards in the original two large yards. The architect adjusted the relationship between the original building and courtyard to the relationship between the building, the private courtyard, and the public courtyard. Each room is open to the private courtyard, and through the hole in the partion wall, the space becames interesting. An original shared courtyard became a group of courtyards that shared and privately coexisted.
