项目坐落于东京上池袋密集的木造建筑区，道路状况的改善与更多抗震阻燃建筑的建造，为当地居民创造了一道防止火势蔓延的屏障，增强了城市抵御灾害的能力。

The area around the site is a densely built-up wooden area where roads are being improved and buildings are being made non-combustible and earthquake-resistant as a fire spread barrier zone in order to create a city that is resistant to disaster prevention.

项目的场地面积因城市规划道路而减半，呈现出宽而浅的形态。为了传承这片三代人生活过的土地，并照顾一直在此居住的年迈母亲，业主决定在场地上重建两栋住宅。建筑师在场地的东南侧设置了一个采光花园，以确保光线与空气能够从密集的城市环境中穿进住宅，为居住者提供舒适的生活体验。

The area of ​​the site was halved by the city planning road project, and the depth was shallow and the width was wide. The owner thought about the land where they had lived for three generations and continued the life of his elderly mother. The two-family house was rebuilt. A light garden was set up on the southeast side to ensure ventilation and daylighting from the dense area side, aiming to balance the comfort of living.

L形的住宅平面围绕着采光花园排布，为父母与子女的生活空间之间留出了一段适当的距离，保证了各自的隐私与舒适度。房屋结构综合了承重墙与300毫米方形柱子构成的框架结构。这种结构为立面开窗赋予了更多的自由，使建筑面向采光花园的一侧更加开放。

The L-shaped plan that surrounds the light garden allows parents and children who live together in cross-section and plane to maintain an appropriate distance. The structural plan is a hybrid structural plan that incorporates a wall-type structure and 300mm square pillars. Those Increases the degree of freedom of the opening facing the light garden.
