The plan was to provide an entrance approach while also incorporating the concept of the city of Kichijoji, which was structured to create a highly circular urban environment.
Basically, the form to be used is a primitive and easily recognizable square, and as part of the "Square Series," which is developed in the openings, etc., it was planned so that people in the town and residents can recall a single world view. The shape of the RC structure is designed to fit in with the shape of the plantings.
