Both sides are sandwiched between door-built houses and climb the alley approximately 2.5m in width to be slanted while curving gently slowly. Moat crowded space appears a little while having the scale like the alley which I walked.
The ground is at the position that fell approximately 1m and is not recognizable clearly where is the site of this building. I learn the sense that went into the ground when I just go down several steps of stairs. The people are surrounded by the buildings, but the sky is like opening without a thing to block. There is a step of approximately 5m, and the front opens out.
I just drew a connected alley into the center of the site and I divided the volume into both sides and located it. The tenement house divided into two is divided in two by 12 dwelling units, and only the number has form and area.
