This project started with a client who wanted to make good use of a site with all four sides facing roads, like a small isolated island, north of Koroen station. The area was only about 230m2 and as long as 50m in length in the shape of a thin triangle with a 6.5m short side and was also at an incline. So it had rather challenging conditions for a rental property.
In order to guide people smoothly to each unit, utilizing the slope of the land we arranged a shared stairway in the center which connects two buildings. Also, with the stairway in between, we made a half-floor difference in the buildings' height so that people feel it’s easier to move from floor to floor. Further, the stairway looks like a trapezoid seen from above, which makes people naturally look various directions when they go up and down. In addition, the sway of an ash tree planted in the center of the stairway and the sunshine filtering through it creates a pleasant mood even when people are moving from shop to shop.
Although we needed to meet the stringent setback regulations for all the four roads around the building, we kept as much space as possible in both plane and cross-section surfaces by using the sky factor. In order to reduce the pressure from the walls facing the roads, we made custom-made colored brick tiles for the first floor walls, and cracked them by hand before applying to create the warmth of “hand work” and to suit the context of the area called “Hanshin-kan (area between Osaka and Kobe) modernism”.
