An Exploratory Study on Changes in the Built Environment Before and After Public Rental Housing Development

This study aims to address the variability in empirical analyses regarding the impact of PRH(Public Rental Housing) on surrounding housing prices by investigating the environmental diversity of PRH from an urban design perspective. We analyzed the characteristics of 183 Happy Housing complexes in Seoul using maps and street views, examining the complexes' attributes, adjacent infrastructure, and neighboring buildings. Additionally, an in-depth analysis was conducted on 11 Happy Housing complexes used in previous empirical studies. The results showed that 69% of the areas with Happy Housing experienced changes in neighborhood facilities, 66% saw improvements in roads and sidewalks, and 79% had enhancements in green spaces. These findings suggest that the supply of Happy Housing can positively influence the local environment, although the impact may vary in areas without infrastructure improvements. Furthermore, the relationship between Happy Housing supply and adjacent building development exhibited relatively low statistical significance, and the in-depth analysis also found it difficult to establish a consistent relationship between the two factors. These outcomes highlight the importance of considering environmental changes and connectivity when analyzing the external effects of PRH. This study underscores the necessity of a comprehensive approach in evaluating the external impacts of PRH by factoring in the surrounding environmental changes and their interconnections.
