The clients are a family (a father and a son) who are psychiatrists and have been running a mental health clinic in Minato ward in central Tokyo for fifty years. Although the clinic has a long history housed in its current old wooden building, it became necessary for it to relocate due to a road schedule based on an urban plan formulated immediately after the Japanese defeat in World War II. In accordance with the relocation, the family decided to purchase an old building a five-minute walk from the clinic and build a new building on the site in order to reopen the clinic there. The beginning of this project was to the dismantling of the old building.
