Recently, need for the mixed-use residential complex which offers luxury housing service has been highly differentiated as demand for mixed-use housing increases in the housing market. Past literature shows a vast lines of quantitative and hedonic variables affecting housing price, however, factors that determine luxury housing price does not exist at all. The study hypothesizes difference on hedonic variables determining luxury housing price and analyzes each price determinant factor by housing size and form. When the data were analyzed with respect to housing size, exclusive residential characteristics were found to be statistically significant for large size. On the other hands, residential characteristics such as number of community were important for small size. When the data were analyzed with respect to housing style, housing expert opinion on security system evaluation was important for mixed-use housing style. For apartment/vila style, a few location characteristics and resident perception such as preference were crucial in determining luxury housing price. Finally, several implications are derived based on heterogeneity of the results.
