如今，日本的许多城市住宅用地都被分割成几块，留下狭小的空间，一般来说，各种功能都是围绕着一间单间中央的楼梯布置的。这可能是充分利用有限空间的解决办法。我关心的是，在房子里总是能看到楼梯和其他细节是否舒服。我敢于划分，以限制能见度，给现有的空间一种扩展的感觉。

Many of urban housing lots in Japan these days have been divided into pieces to leave small, narrow spaces, where, in general, various functions are laid out around a stairway in the center of a single room. This may be a solution to fully utilize the limited space. My concern is whether it is comfortable to be in the house with the stairway and other details of the house always in sight. I dared divisions to limit the visibility to give a sense of expanse to the existing space.

我使用材料作为结构构件和耐火板，在墙面处理的基础上，遵守严格的防火规定，允许使用耐用性高、外观平静的经过烘烤的雪松的光洁度。

I used material serving both as structural member and fire resistant board for the basis of wall surface treatment to comply with strict fire prevention regulation, which allowed using finish of a broiled cedar of high durability and of a calm appearance.

当你踏进门厅时，你将面对一个混凝土地板工作室，它的水平和外面的地面是一样的。客户将骑他的摩托车在那里维修或储存和享受DIY爱好。左边是一间半地下的卧室，整个室内都用泡桐木来控制湿度。从一个小水平的楼层，你将走上二楼的餐饮和厨房，或进一步转身，三步到客厅，或进一步右转到楼梯井，或进一步转到三楼。你将因此螺旋上升。

When you step in the entrance hall, you will be facing an atelier of concrete floor the level of which is the same as the outside ground surface. The client will ride his motorbike in for maintenance or for storage and for enjoying DIY hobbies there. On the left provided is a bedroom of half underground, where the entire interior is finished with paulownia wood for humidity control. From a little leveled up floor you will be stepping up to the dining and kitchen on the second floor, or further turn around and step up by three to the living room, or further turn right to the stairwell, or further turn to step up to the third floor. You will be thus rising spirally.

从三扇窗户中引入阳光直射的开放式气氛起居室，空气平静的餐厅，高耸六米的天窗，阳光一直反射到房间里，让房间始终保持柔和，顶层有一个浴室，阳光充足，但隐私得到保护-所有这些不同性质的房间都与协调结合在一起。楼梯井的内部无法从每个房间看到，但阳光通过天窗和楼梯井传送到每个房间。这种隐蔽性加上漏光，给人一种在一座小建筑中不断扩大空间的感觉。

The living room of open atmosphere with direct sunlight introduced through the three windows, the dining room of calm atmosphere with the skylight six meters above through which the sunlight is reflected down to fill the room with constant softness all the time, and a bathroom on the top floor filled with sunlight and yet privacy is secured – all these rooms of different nature are combined with coordination. The inside of the stairwells cannot be seen from each room but the sunlight is delivered to each room through the skylights and through the stairwells. This invisibility together with leaking light is giving a sense of ever expanding space in a small building.
