In this study, the analysis result shows that NPV became '-' value if 5th floor, 20m regulating and that NPV increased if 7th floor, 28m regulating but relatively low value compare to the self-maintainability and the block maintenance. This study aimed to suggest the necessity of public funding for the self maintenance and improvement of perception on benefits from redevelopment project as landscape districts or maximum height districts changes to the housing redevelopment zone.
