项目场地位于东京市中心一个安静的居民区，业主是一对在此经营牙科诊所的夫妻，业主的家属也居住在附近。该项目的主旨是在建筑中间开辟一个大型中央庭院，使建筑内所有的房间都能够朝向花园，并在室内与室外形成过渡区域。

The site is located in a quiet residential neighborhood in the heart of Tokyo, where the client run a dentistry clinic as husband and wife practitioners. Their relatives have also built and live on the premises. The concept in this case has been to have the house enclose a large central courtyard so that all of its rooms will face the garden, to create an intermediate area between the indoors and the outside world.

▼项目概览，overview

仅凭住宅深灰色的铝锌合金外墙和半透明玻璃窗，很难想象住宅内部会有怎样的居住空间。但一旦走入住宅，就能感受到不同空间氛围所带来的强烈对比。洒满阳光的住宅内部宽敞而舒适。

While it is impossible to imagine the interior living space based on the dark gray galvalume-steel outer wall or the closed façade made of half-mirrored glass, moving inside one becomes conscious of the comfortable contrast afforded by the expansive space, suffused with natural light.

▼住宅入口，entrance

柔和的光线透过入口旁的落地窗射入住宅一层，营造出一个以灰色为主的别致入口空间。从主卧室和儿童房可以看到种在中央庭院的紫荆树，另在后方设有酒店风格的浴室。住宅的设计同时注重了业主的隐私保护。
