架构师提供的文本描述。这是一座有近30年历史的建筑的翻修工程。首先，我把这座建筑放在了一个骨架上，我把一楼的起居室改成了二楼。

Text description provided by the architects. It is a renovation project of a nearly 30 years old building. First of all, I put the building in a skeleton state and I changed the living room which was located on the first floor to the second floor greatly.

在日本的城市地区，房屋在密集的条件下存在。因此，一楼部分受到周围建筑阴影的影响，非常阳光明媚。二楼的起居室营造了阳光舒适的环境。

In urban areas of Japan, houses exist under dense conditions. Therefore, the first floor part is affected by the shade of the surrounding building, it is very sunny. The living room arranged on the second floor has created a sunny and comfortable environment.

此外，每个地方都有供猫使用的楼梯和厕所。猫的厕所被放置在人类厕所的通风路径上，我们建立了一个共存的环境。在起居室里，架子要升到横梁上，都是作为楼梯安装的。

In addition, stairs and toilets for cats are arranged in each place. The toilet for cats was placed on the ventilation path of the human toilet, and we built up a coexisting environment. In the living room shelves to rise to the beam are installed as a stairway.
