这是一个改造拥有50年历史的传统日式房屋的项目，因为太大，两个成年人无法居住。原本是走廊+边角型，室内整体比较暗，白天北侧也几乎没有光线。

This is a project to reduce a traditional 50 year old Japanese house because it is too large for two adults to live in. Originally, it was a corridor + marginal type, and the interior was dark as a whole, and there was almost no light even on the north side during the day.

根据检查，还发现现有的主房没有抗震能力，只有东侧的扩建部分有支撑，所以整体抗震平衡性较差。因此，我们决定将建筑西侧（约占整体的1/4）拆除，留下 “框架和屋顶”。

According to the inspection, it was also revealed that the existing main house had no seismic resistance and only the eastern extension was braced, so the overall seismic balance was poor. Therefore, we decided to dismantle the building west side (about 1/4 of the whole) leaving behind the “framework and roof”.

这栋房子的日本屋面瓦片相当不错，我们觉得在檐口一侧，瓦片的精华是有效的。因此，创造了一个半户外的空间，通过在地基内侧涂抹碎石，变成了一个具有神秘质感的岩石花园。

The Japanese roof tiles of this house were quite good, and we felt that the essence of the tiles was effective on the gable-end side. As a result, a semi-outdoor space is created, and by applying gravel to the inside of the foundation, it becomes a rock garden with a mysterious texture.

此外，在岩石花园和内部空间的边界处，使用了RC墙。将RC打在没有达到木梁的高度，将现有的木柱吞噬并收紧，使其成为 “短柱”，进行抗震加固，RC的效果并不是太好，期望作为一种质感，唤起新的生命。这面RC墙从房屋延伸出来，也是遗址上神龛的大门。

Furthermore, RC walls were used at the boundary between the rock garden and the interior space. Hitting RC at a height that does not reach the wooden beam, swallowing existing wooden pillars and tightening them to make “shorter columns” and perform seismic reinforcement that RC is not too effective, and expected as a texture that evokes a new life. This RC wall extends from the house and also serves as the gate of the shrine on the site.
