At the request of his friend and colleague Mr. Mohsen MIRHEYDAR, directing a school redevelopment programme, Keyvan participated in an exhibition in Tehran. He proposes via series of his own hand drawing panels, architecture for warm and dry climate in Iran. All buildings are north south oriented with all façades filtering the direct sunlight. Classes are double oriented facilitating a natural draft and enjoying a pleasant north light for all classes and labs. Every class has its airy sanitary units cleaned by students at early ages tackling a major problem in Iran and most of developing countries.
