项目对一座位于大阪Tamatsukuri的三层钢结构独栋住宅进行了改造。建筑坐落在城市中一处轻松方便的地块上，与一条宽敞的马路相邻，光照充足。尽管改造受到了一定的建筑限制，但是建筑师依然找到了合适的方式实现项目的更新目标。

Renovation project of a 3-story steel frame single-family house in Tamatsukuri, Osaka. Situated in a convenient and relaxing location in the city, it is connected to a wide road and has sufficient amounts of natural light. While the renovations came with architectural limitations, we explored methods only achievable through renovation to reach the goals of the project.

虽然建筑的房龄仅有十五年，相对较新，但它的保温性能并不理想。由于项目位于朝北的街角地块上，设计着力于通过外保温技术减少室内温度的变化，包括在外墙上增加聚氨酯保温板。此外，由于原立面开窗数量较多，建筑师封堵了部分窗户，以一扇巨大的双层固定玻璃窗替代，达到更好的保温效果的同时，让北侧温暖的阳光照入室内。

While the building is 15 years old and is relatively new, it was not what we would call an insulated house. As it is on a corner plot facing northeast, we focused on external insulation to reduce room temperature fluctuations by adding layers of urethane to the external wall. Additionally, as the existing number of window sashes was excessive, we blocked off some and installed a new large double-glazing fixed window for more effective insulation and to allow warm light from the north side into the building.
