-The office folding the nature that is hiding in a city- As typical environment in Tokyo, this site is facing the front road along only west side and rest three sides are surrounded by adjacent site. It is the most difficult condition to take in the exterior environment. This design realized environment-consciousness and comfortableness together by connecting people and nature far beyond the site boundary. In this project we folded the nature which is very important element to support our activities and which is hiding in a city around the workplace.
