架构师提供的文本描述。这对夫妇和他们的孩子住的小房子坐落在东京人口稠密的地区。虽然邻近的房子很近，但我的目标是设计出一座比住在城市里的物理狭小的房子更好的房子。我把4m×4m的建筑布置在工地中心面积34m2的尽可能小的地方，为周围的光和风的流动创造了一些空间。通过腾出空间，可以避免挫折，它有9米高的体积，就像一座塔。内部结构简单，由四层板隔开，由螺旋楼梯连接。特别是，通过制作一些非常薄的地板(厚度70毫米)，上下地板接近并连接了房子的整个空间，不间断。

Text description provided by the architects. The small house which the married couple and their child live stands at the densely populated area in Tokyo. Though the neighboring houses is very close, I aimed to design the house which exceed the physical narrowness living at the city.  I laid out the 4m×4m building that as small as I can at the center of site area 34m2 and made some space for flowing of light and wind around it. And by making the space, it’s possible to avoid setback regulation and it has the 9m high volume like a tower. The inside is simple structure what is separated by the 4 floor boards and is jointed by spiral stairway. Especially, by making some extremely thin floor boards (thickness 70mm) , the up and down floor boards got close and connected the whole space of the house without a break.

房子周围的空间是有用的，让光线和风进来。房间的墙壁与外面接壤，所以我把窗户放在与周围环境相协调的最佳位置。窗户对着小房间太大了，每当窗户打开或关闭，里面的景物就会发生巨大的变化。特别是在二、三楼，每个房间都有一个大的铰链门，如果打开了，房间的内部就像在外面一样被光和风所包围，我做了薄薄的地板来连接他们的生活，制造了向城市敞开的大窗户，我的目标是超越分割，例如，上楼梯和下楼梯，内外，建筑物和城镇，等等…。扩大房子的整体形象。

The space of around the house is useful to let light and wind in. The wall of the rooms borders the outside, so I put windows in the best position that harmonizing with its surroundings. And the window is so big against the small room, every time the window opens or closes, the inside view dramatically changes. Especially, at the second and third floor there is a large hinged door each room, if it is opened, the inside of the room is enveloped in light and wind as if you are outside. By making the thin floor boards for connecting with their life and making the large windows what are opened toward the city, I aimed to exceed the segmentation, for example the up stair and the down stair, the inside and the outside, a building and the town, etc… to broaden the whole image of a house.
