架构师提供的文本描述。该地点位于住宅区，从主干道很容易到达。这是一个所谓的“旗杆形状的地点”，意思是长方形的地点位于一定距离的公共道路，并连接到它的一条长而狭窄的道路。四周是两层楼和三层楼的建筑.

Text description provided by the architects. The site is located in a residential district, which is easily accessible from a principal road. It is a so-called “flagpole-shaped site”, meaning that the rectangular site is located at some distance from the public road and linked to it by a long and narrow path. The site is surrounded by two-story and three- story buildings on the four sides.

客户要求建立一个室内车库，这样他就可以从客厅看到他心爱的汽车，也可以看到带有太阳能电池板的倾斜屋顶。

The client requested an indoor garage so that he can enjoy looking at his beloved car from living room and also an inclined roof with solar panels.

由于两个原因，我们决定建造一栋单层木屋；与工地面积相比，客户要求的建筑面积相对较小；由于土地被用于耕作，地面土壤的允许承载力较低，因此建筑物必须轻型，建筑面积相对较大。

We decided to build a one-story wood house because of two reasons; the floor area requested by the client was relatively small in comparison to the site area; and the allowable bearing capacity of the ground soil was low because the land had been used for farming and therefore the building had to be light with a relatively large building area.

我们最大的挑战是在一层楼内提供自然光，并确保屋顶上有足够的太阳能，在拥挤的条件下被两层和三层的建筑所包围。这也是至关重要的设计与周围的城市景观和谐的房子。因此屋顶设计成为我们提出建议的关键，我们从那里开始我们的设计。

Our biggest challenge was to provide natural light inside the one-story house and also to ensure enough solar energy on the roof, within the congested condition surrounded by two-story and three-story buildings. It was also essential to design the house in harmony with the surrounding townscape. Therefore the roof design became the key to our proposal, and we start our design from there.

屋面由传统日式斜屋顶和平顶组合而成，是一种典型的现代建筑风格。

The roof is composed of a combination of the traditional Japanese-style inclined roof and the flat roof, which is a typical modern architecture style.

倾斜屋顶的大小取决于太阳能电池板的数量，以产生足够的能源为这所房子服务，它被安装在工地的中心，以避免周围建筑物的阴影。天花板与屋顶的倾斜方向一致。屋顶结构高于等间距的柱子，这些柱子建在东侧和西侧的平屋顶上。

The size of the pitched roof was decided by the numbers of solar panels required to generate sufficient energy to serve this house, and it was installed at the center of the site to avoid shadows of the surrounding buildings. The ceiling follows the inclination of the roof. The roof structure is raised above the equally spaced columns, which are built on top of the flat-roofed volumes on the east and the west sides.

从室内空间看，居民可以通过倾斜屋顶和两侧平顶之间的洞口，欣赏到通透的天空景观。从外面看，倾斜的屋顶靠在两边简单的和水平的体积上，这三个区域中的每一个都被分配给房子的不同功能。

From the interior space, the residents can enjoy the unobstructed view of the sky through the openings between the inclined roof and the flat roof on both sides. Seen from outside, the inclined roof leans on the simple and horizontal volumes on both sides, and each of the three areas is allocated for different functions of the house.
