要被爱很久，以下4点是必需的。

To be loved long following 4 points are required.

-最高限额

-High ceiling

-两个或两个以上方位的照明和通风

-Lighting and ventilation from two or more azimuths

-高抗震性能

-High earthquake-resistant performance

这听起来很普通，但却是日本出租公寓设计中最容易被经济理性(最大的容量消化、建筑成本最小化)所牺牲的内容。

It sounds like all ordinary, but is the contents which are apt to be sacrificed by the reason of economic rationality (the biggest capacity digestion, building cost minimization) in the design of apartment for rent in Japan.

起初，我们想建造一座高一点的建筑，以确保高天花板和高视野。阴影的调节规定了这个地点高度的上限。经过对各种建筑形式的检查后，我们发现了建筑的位置和形状，这些都可以使建筑物达到我们想要的高度。我们尽可能地在场地的南侧建一座建筑，并制作了菱形的平面图，将南面和北面的墙角组合在一起，在上午8：00形成一个阳光角。在冬至的时候。此外，从距离工地边界的北侧，也没有封闭的感觉，在下一层。

At first we thought to make a building high to secure high ceiling and view. Regulation of shadow prescribed the upper limit of the height at this site. As a result of having examined various building forms, we found placement and the shape of plan which could make a building high as we wanted. We put a building to the south side of the site as much as possible and made diamond-shaped plan which put the angles of the wall of the north and south surface together to a sunlight angle at 8:00 a.m. at winter solstice. Furthermore, by the distance from the site border in the north side, there is not the occlude feeling in the lower floor either.

其次，典型楼层由2个住宅单元(每50m2)组成，以获得足够的照明和通风，每个住宅单元面向外部3个方向。

Next, Typical floor consists of 2 dwelling units (for each 50m2) to get enough lighting and ventilation and each dwelling unit faced outside in 3 directions.

我们将地震的水平功率设定为1.25倍，这与公共建筑的水平是一样的。假设，我们把结构的成员变成最小的尺寸，使空间具有紧张和膨胀的感觉。

And we set setting against the horizontal power of the earthquake to 1.25 times that became the same level as a public building. Assuming it, we made members of structure into minimum size to make space with feeling of strain and expanse
