Because of the rise in land prices of big cities in Japan, it has been becoming desperately difficult to Keep up enough space for living. The present idea of a plane planning and management of land use can no more stand for the needs of the time. Three-dimensional management of space like setting up flight routes of airplanes is absolutely necessary to maintain space for living. From this point of view, first of all, we classified space attribute and space use, and on its basis we made investigation and comparison. By dividing space attribute into three items (public and private space, over and under space, inner and outer space), space can be classified into 8 types. (1) public・Eover・Eouter space (2) public・Eover・Einner space (3) public・Eunder・Eouter space (4) public・Eunder・Einner space (5) private・Eover・Eouter space (6) private・Eover・Einner space (7) private・Eunder・Eouter space (8) private・Eunder・Einner space Space use is classified into 5 items from the point of city level (building floor, circulaion, greeneries, waters and void), and it is also classified into 10 items from the point of architectural level (facilities for residence, facilities for service, facilities for business, facilities for medical care, facilities for sleeping accommodaion, facilities for education, facilities for culture, facilities for amusement, facilities for industry and facilities for storage and garage). Applying the above classification of space attribute and space use, we investigated three areas in Tokyo (Ginza area, Kinshichou area and Saginomiya area). We used 5 m mesh method in 500m×500m zone from each area. We revealed the present situation of space use of each floor of buildings, and we made the chart of space attribute and space use of each area.
