A STUDY ON CHANGES IN HOUSING LOTS AND DWELLES AT SUBURBAN DETACHED HOUSING AREAS IN STAGE OF GENERATION CHANGE: Case study to focus on building agreement zone and non-zone in “H” housing area in Yokohama city

This study aims to investigate the land subdivision and the movement of dwellers at a suburban detached housing area in the stage of generation change. We surveyed “H” housing area built in the 1970s in Yokohama City and compared the building agreement zone with land subdivision and non-zone. Housing lots are not divided and dwellers continue living their lots in the agreement zone. In contrast, many of lots are divided, and rebuilding and new dwellers' moving-in are active in non-zone. Therefore the subdivision control of building agreement works well only in agreement zone and influences on changes of dwellers.
