Developing terminology for side facades and side setback areas in Japanese neighborhoods: a study on?utility and perception

摘要

Abstract The contribution of front or back yards to sociability has been the subject of several studies. No such finding however is evident for side setback areas, short distances kept between adjacent buildings, which in the case of comparatively dense Japanese urban neighborhood environments can be as short as a few decimeters. The present study locates side setback areas and building facades that look towards them in Japanese planning terminology, and examines them from the residents’ point of view. The data for this preliminary step of the research was collected based on a carefully designed and explained 2014 survey of 190 academics scholars throughout Japan. The results suggest that no demographic characteristic or housing type, number of floors or period of time living in the area were shown to be significant in residents’ perceptions towards the side setback areas. Those who had no side setback area were more concerned with their privacy, smoke, sound or darkness whereas those with side setback areas were more satisfied. As for preferences, having a Green Wall, Terrace/Balcony and Living/Dining were the preferred choice of those with side setback areas. All respondents tended to perceive the spaces as valued for the light and ventilation they provide. Several activities such as storage, parking and drying clothes were common among the respondents’ perceptions of activities suitable for these spaces.
