The house is located in an area with a high density of old wooden houses in Tokyo.
When constructing a new building in that area, it is necessary to increase the fire protection performance of the building.
This is a home for a total of 3 people (mother and 2 daughters) and 4 cats.
Mother lives on the first floor, and Daughters live on the second floor and in the loft.
Cats are free to stay anywhere, but in this house, the flow lines for people and cats are separate.
At some points, the two paths intersect.
At intersections, cats and humans meet and interact.
