This is the refurbishment of the unit for my parents. Kawaguchi Apartment has built in 1964. There are 80 unit. The owner, Matsutaro Kawaguchi was the author in Japan, and His son, Hiroshi Kawaguchi built this apartment for the actor and artist so that they would have wealth lifestyle here. I have refurbished a unit of this apartment. The garden and the entrance has connected Doma area made by mortal so that the parents can walk through without taking off their shoes as they will work gardening. External existing tiles has repeated in to the kitchen in order to have continuity. Taking off the doors between Living space and Bed room, the parents can be aware each other.
