Abstract
The authers studied the car park around the 12 large buildings in the C.B.D. of the Osaka City. In this survey, the selected buildings have sufficient spaces around them, and their parking demands are satisfied now. Judged from the parking conditions, there are distinct differences of parking conditions between the visitor's car and the officer's car. Each building shall be forced, therefore, to provide an amount of on-site space which will be consisted of garages for its officer and car parks for visitor to it. These spaces shall be required proportional to its needs, which will depend upon their floor space and type of use.
