Abstract
This study was conducted to investigate housing needs and preferences for housing renewal among residents in deteriorated hillside according to level of household income. A cross-sectional survey was used and the data were collected in February 2012. Participants were 1,746 residents who had lived in hillside or flat areas in Seoul, Korea. Residential satisfaction, housing needs and preferences for housing renewal, and general characteristics such as level of household income were surveyed using self-reported questionnaires. Participants were categorized by level of household income as lowest-income class, low-income class, and middle-income class. Collected data were analyzed with descriptive statistics, factor analysis, cluster analysis, One-way ANOVA and Regression using the SPSS 18.0 program. The findings are as follows. Major satisfaction factors were different among income level groups in hillside residents. Community facilities and the parking condition in lowest-income group, supporting facilities in low-income group, and economic efficiency and safety in middle-income group were the major factors. Lowest-income residents in hillside preferred to promote housing renewal projects and regulatory support system than residents in flat area. These results may be useful to plan hillside neighborhoods and houses. Further research is required to improve the design guidelines and to reform regulations for practical designing.
