首先在房子的几乎正方形的地块上画出一个最大的可能的正方形平面图。然后在外广场内画出一个稍小的正方形平面图，然后围绕广场中心顺时针旋转32.4度，在外广场内形成四个直角三角形；这些是构成房屋的元素，外广场、内广场和中间的四个直角三角形。

A largest possible square floor plan was first drawn within the almost square lot of the house. Then a slightly smaller square plan was drawn inside the outer square, then it was rotated around the center of the square clock-wise by 32.4 degrees creating four right triangles inside the outer square; these are the elements which constitute the house, outer square, inner square and four right triangles in-between.

直角三角形空间作为房屋房间的入口门廊或阳台，同时，从总面积和建筑面积中减去足够的面积，将面积控制在允许的范围内。如果房子建在外广场上，其总建筑面积将超过预算或法定建筑覆盖率内可建造的建筑面积。

Right triangle space serves as entrance porch or balcony of rooms of the house, and at the same time, subtracts adequate floor area from total floor area and building area to manage the area within allowed limit. If a house is built on the outer square, its total floor area would exceed the floor area which can be built within the budget or statutory building coverage ratio.

最大的窗户被设计在面向直角三角形的墙壁上，而适度的开口被设计在外广场一侧的墙壁上，因此，从窗户看到的是业主家的墙壁（在直角三角形空间内），而不是隔壁，避免了不拉窗帘就能看到隔壁的情况。

Largest possible windows are designed on the walls facing right triangles, and modest openings are designed on the walls on the side of outer squares, thus, the view from the window is the wall of the owner’s house (inside the right triangle space) and not the next door, avoiding the sight from the next door without drawing the curtains.

由于来自房屋的视线没有被窗帘挡住，外广场的墙壁可以被认为是室内的墙壁，给人的感觉是空间比实际面积大。在外广场内，墙壁被涂成哑白色，这样，通过四个直角三角形墙壁的光线就会温和地反射到墙壁上。

As the sight from the house is not blocked by curtains, the wall of the outer square can be perceived as the wall of the interior, giving the impression of larger space than the actual floor area. Inside the outer square, the walls are painted in mat white color, so that the light pouring through the four right triangle walls is mildly reflected on the walls.

房子建在邻居家，形状和大小相似的地块普遍存在，在地块内，新旧房屋几乎完全建在地块内。房屋前四米宽的狭窄街道是一条社区街道，其所有权由临街房屋的业主共享。在这个社区里，房屋和居民的关系似乎很密切，有些家庭已经生活了几十年，有些则是最近才搬来的。年龄段不同，不同的生活方式并存。

The house is built in a neighbor where lots of similar shape and size are prevalent and within the lots, old and new houses are built almost fully within the lots. The narrow street of four meters in width in front of houses is a community street whose ownerships are shared by the owners of the houses facing the street. In this neighborhood where houses as well as relationships of the residents seems close, some households are living for decades and some have just moved recently. The age groups are diverse and different life styles co-exist.

一家四口，一对夫妇和两个孩子，从不同的邻居那里搬来，在这里开始新的生活，他们的隐私受到房子的保护，房子在屋内的生活和外面的邻居之间提供了缓冲。房子的目的是为了保证室内的宽敞和安静。

The family of four, a couple and two children, who are moving from different neighbor and starting a new life here, have their privacy protected by the house which provides buffer between the life inside the house and the neighborhood outside. The house is meant to secure interior spacious and quiet.

下午，房子前面的社区街道变得很热闹，放学后的孩子们路过，购物后的大人们在聊天，还有人家里传来的练琴声。我们希望随着时间的推移，邻居和这个家庭之间的距离和关系会逐渐拉近，这个家庭会融入社区的一部分。

In the afternoon, community street in front of the house gets busy with children after school passing by, adults after shopping chatting and sounds of piano practice from someone’s house. We hoped that in time, the distance and relations between the neighbor and the family would gradually get closer and the family would blend in as part of the community.
