客户的前房子，就站在这个地方，是一栋两层高的木屋.邻近的地方很近，自然的光线没有进入老房子。因此，客户要求家庭房间(起居室、就餐区和厨房)尽可能大，不要有柱子或道路墙，以及进入房屋的自然光线，特别是进入家庭房间的光线。

The client’s former house, which stood at this site, was a wooden two-story house. The adjacent sites were close and natural light didn’t enter into the old house. Therefore the client requested the family room (living area, dining area and kitchen) to be as large as possible without pillars or road-bearing walls, and that natural light that comes into the house, especially into the family room.

首先，由于场地狭窄，大楼的体积占了尽可能多的场地，根据客户的生活方式，夫妇的卧室和潮湿的地方放在一楼，家庭房间放在一楼，儿童的房间放在二楼，露台放在屋顶上。由于结构原因，大楼一楼路旁的大开口无法打开。所以，我把二楼的体积旋转了14度，在大楼的轴线上，旋转墙和外墙之间的间隙变成了空隙。天窗设置在虚空的上方，目的是让自然光线落在一楼的家庭房间里。

First, since the site was narrow, the volume of the building took up as much of the site as possible. According to the lifestyle of the client, the bedroom of the couple and wet areas were placed in the ground floor, the family room was placed in the first floor, the rooms of children were placed in the second floor and the terrace was placed on the roof. For a structural reason, the large openings were not able to open out on the road side of the first floor of the building. So, I rotated the volume of the second floor 14 degrees for the axis of the building, and interstitial spaces between the rotated wall and the outer wall of the building became voids. The skylight was set up in the upside of the void, and is intended to allow natural light to drop on the family room of the first floor.

另外，二楼平面上两面墙旋转14度，其中之一也倾向于垂直，与楼梯重叠的部分向上翘起，变得像折纸或小面一样。这种倾斜墙通过偏离规范来释放人们的情感，同时，倾斜程度的触觉和反射这种倾向的光线产生了一种新的物理感觉。

Moreover, one of two walls rotated 14 degrees on the plan of the second floor is also inclined to the verticality, and the part which overlaps with stairs is turned up, and has become like origami or a facet. This inclined wall frees people's feeling by deviation from the norm, simultaneously the sense of touch of the degree of inclination and the light to reflect of that inclination cause a new physical sense.

这座大楼的白色盒子和附近的建筑完全不同。它是第二层圆柱形体积旋转14度进入建筑物的外观。箱形悬臂楼梯漂浮在空隙中.

The building’s white box is completely different from the building of the neighborhood. It is the appearance which the cylindrical volume of the second floor rotated 14 degrees penetrates into the building. Box-shaped cantilevered stairs are floating in the void.
