架构师提供的文本描述。东京郊区的一所家庭住宅。

Text description provided by the architects. A family house in the suburb of Tokyo.

该地块位于西北角，毗邻南部和东南部的空置地段。这使得它不可能预测未来的日照量。因此，我们设计的目的是在任何情况下都允许充足的自然光线进入房屋。

The site is a lot in the northwest corner, adjacent to vacant lots to the south and southeast. This makes it impossible to predict the amount of daylight it would receive in the future. For this reason, we designed with the aim of allowing ample natural light into the house in any circumstance.

客户要求空间作为业余爱好，特别是用于天文观测的屋顶甲板，以及户外用品和游戏的阁楼。我们寻找一个满足所有这些条件的简单解决办法。

The client requested spaces for hobby, especially a roof deck for astronomical observation and a loft for outdoor goods and play. We looked for a simple solution to meet all those conditions.

首先，我们放置了一个主要的简单体积形状的山墙屋顶。之后，通过从主卷中添加和抽取小卷，我们为业余爱好和乐趣创造了内/外空间。这连接家庭空间和私人空间，允许自然光穿越房间，同时传输大气。

First, we placed a main simple volume in the shape of a gable roof. After that, by adding and pulling small volumes from the main volume, we created inner/outer spaces for hobby and pleasure. This connects the family spaces and private spaces, allowing natural light to travel across the rooms while transmitting atmosphere.

这些房间被分配用来邀请自然光从阁楼的顶部侧窗一直延伸到地面的起居室的玻璃地板。光线被天花板的镜子反射，穿过MBR的玻璃地板，到达生活空间。餐厅和卧室由外楼梯下的音量连接到屋顶甲板上，这样房间就可以共享自然光。

The rooms are allocated to invite natural light from the top side window of the loft all the way to the glass floor of the living room on the ground level. Light is reflected by the ceiling mirror, crosses through the glass floor of the MBR and reaches the living space. The dining room and a bedroom are connected by the volume under the outer stairs to the roof deck so that the rooms can share natural light.

露台和屋檐的设计是为了在夏天阻挡阳光和热量。房子在冬天是很好的绝缘，并配备了内置的空气循环系统，由太阳能电池板供电。

The terrace and the eaves are designed to block sunlight and heat in the summer. The house is well insulated in the winter and is equipped with a built-in air circulation system powered by solar panel.
