Private space, shared space and private housing prices in Hong Kong: An exploratory study

This exploratory study examines the relationship between internal space, shared space and private housing prices. Housing floor area is an ambiguous concept in Hong Kong because it covers a possible exaggeration of the amount of ‘private space’ exclusively enjoyed by the owner and an unidentifiable portion of ‘public space’ shared with other owners within the development. Using hedonic pricing models, this study has found that different distributions between private and shared space command different values from the housing buyers. Shared communal space generally exerts a downward pressure on housing prices. The buyers are willing to pay more for the private space and some desirable forms of communal space. A higher willingness-to-pay for the desirable attributes such as clubhouse indicates that the Hong Kong people are increasingly concerned about the quality of living space in the built environment. This study suggests a need of further research into the exact measurement and the different forms of housing space rather than simply taking the stated floor space figures for granted.
