新房子面对现有的车库屋顶作为一个露台，而不是直接连接到现有的花园，在那里的主要建筑，使每个家庭可以独立生活在一定程度上。屋顶的高度在北部被压低，而不是挡住主楼的窗户。在南部的体积提高，以提供一个停车场，也可以看到和通风从街道到现有的花园。

The new house faces the existing garage roof as a terrace instead of being connected to the existing garden directly where the main building faces, so that each household could live independently to some extent. The roof height is held down in the north part not to block up the window of the main building. The volume is raised in the south part to provide a parking and also view and ventilation from the street to the existing garden.

斜弯屋顶是有效的，给建筑物必要的体积，保持阳光到邻近的建筑物。这种方法也给钢琴室带来了声学效果。

Diagonally bent roof was effective to give the building the volume necessary keeping the sunlight to the adjacent building. This method also brought acoustic effect to the piano room.

由混凝土制成的蝶形屋顶将三楼松散地分成两个空间。家具也是用混凝土做的，因为空间太小，不能放置现成的家具。因此，它变得紧凑但舒适的空间，像一个洞穴。

The butterfly roof made of concrete divides the third floor loosely into two spaces. Furniture is also made of concrete as the space was too small to put ready-made furniture. As a result It became compact but cozy space as a cave.
