Within the context of urban design and planning in the 21st century, the increasing number of studies explores positive psychophysiological effects from urban rooftop gardens for enhancing human health and wellbeing, while such psychophysiological studies often require impression evaluation scales for urban rooftop gardens. In this context, this study examined if impressions of two different urban rooftop gardens having flat vs. stepped spatial configurations can be evaluated by UGS (Urban Green Space Scale), which is an impression evaluation scale for recent urban green space projects in Tokyo. Based on the results of the online questionnaire (N=670), confirmatory factor analyses indicated that urban rooftop gardens have poor or unacceptable fit to UGS, while exploratory factor analyses yielded factor structures different from UGS. Our findings suggest that impression evaluations of urban rooftop gardens require new scales.
