尽量避免移走坚硬的小山，屋顶只是盖住了住所。

Avoiding the removal of a hard hill as much as possible, a roof simply covers the residence.

该住宅采用3米×3米网格钢框架支撑屋顶，分阶段扩建。空间由接受卧室、儿童房间和潮湿区域的盒子组成，其余的被排除在盒子之外。上面是透过屋顶的高侧光，它像山脉一样起伏，以45度的角度照亮室内。

Extended in steps, the residence is made with 3 meter by 3 meter grid steel frame that supports roof. The space is composed of boxes that receive bedroom, children’s room and wet area and the rest is left out of boxes. Above them high side light that penetrate through the roof, which undulates like mountain range, in 45-degree angle light up the interior brightly.

在那之前，我们经常考虑由曲面构成的空间，考虑到阴影的表达。为了强调锯齿形屋顶在自然地形上漂浮的情况，介绍了裸露钢梁不加天花板的线表达式。

Until then we often thought about spaces made of surfaces in consideration to expression of shades. Here in order to emphasize the condition of saw-tooth roof floating on natural topography, we introduced line expression of exposed steel beam without putting up ceilings.

光束保持小到100毫米乘148毫米。同样大小的支架是屋顶的一部分，支持高侧光。就像这样，任何结构上的浪费都会被清除掉，但是通过稀薄和45度的乘数效应，我们获得了一种与树下相似的广泛的感觉和平静。另一方面，箱体空间有100毫米厚的墙，由100毫米的方形柱涂漆而成。暴露的屋顶甲板天花板是无光泽的白色和表面软反射光。

The beam is kept small to 100 millimeter by 148 millimeter. The same sized braces are a part of roof that supports high side light. Like so, any structural waste is shaved off, but by the multiplier effect of the thinness and the 45-degree an extensive feeling and calmness similar to under trees was achieved. On the other hand, box spaces have 100 millimeter thick walls made with painted off 100 millimeter square columns. Exposed roof deck ceiling is matt white and the surfaces softly reflect light.

自然地形、栅格结构和面向南方的45度倾斜高边光三种逻辑规则分别是独立的，但相互重叠，并尽可能地扩展安全功能，从而达到了只存在于这个位置的各种景观的建筑。

The three logical rules, the natural topography, grid structure, and 45 degree tilted high side light that face the south, are respectively independent, but overlap each other and secure functionality that extends as far as possible, the architecture that involves various landscapes that only exist at this location was attained.
