This study was conducted to investigate attention restoration effects provided by Seoullo 7017, an elevated public skygarden newly transformed from a 40-year-old overpass as a part of an urban revitalization project. In October 2017, a questionnaire survey utilizing Perceived Restorativeness Scale (PRS) and Zuckerman Inventory of Personal Reaction Scale (ZIPERS) was conducted among employees visiting Seoullo 7017 and 133 valid responses were collected. From a series of factor analyses of PRS and ZIPERS items, four PRS factors were derived from 16 PRS items and named as “Diversion”, “Boring”, “Coherence” and “Compatibility”; and two ZIPERS factors were extracted from twelve ZIPERS items, namely “Positive impacts” and “Negative impacts”. Significant differences in restoration effects and psychological stress were found according to frequency of visits, accessibility, and whether or not Seoullo 7017 was seen from offices. In conclusion, the newly created Seoullo 7017 was found to have healing effects, such as psychological stability and relief from stress, on employees who could easily access the garden.
