Abstract

District plan for urbanized area has a character of tool for incremental urban improvement. By the application of the townscape formation type district plan and the FAR incentive type of district plan, there exist two types of building forms: buildings deregulated from normal building regulation and buildings based on the normal building regulation. This study evaluates the effects and problems of the application of two types of district plans based on the case study at Chuo-City in Tokyo. It clarifies: 1) the deregulation has an effect to promote renewal of buildings, 2) regardless of the deregulation there is no substantial difference on sunshine condition.
