Abstract
This study submits a hypothesis that the psychologically appropriate distance exists between houses, and tests it through a questionnaire answered by residents in three residential areas in the Nagoya region. Psychologically appropriate distance, desirable as a minimum standard at approximately eight meters, may be reduced by twenty to thirty per cent with the employment of vegetation. Roads and neighborhood communication produce limitted effects on the psychological distance. A tentative standard of three meters is proposed for the planning and design of high-density areas difficult to achieve the desirable standard.
