The purpose of this paper is to rate what gives Western-style living rooms and Japanese-style rooms with an alcove their value on the scale by which such value is measured in four dimensions: sociabi1ity/function; sociability/symbol; individuality/function; and individuality/symbol. The dimensions consist of two basic factors: one is something which determines sociability and individuality; and the other - functions and symbols. All of these dimensions and factors are used in assessing an exact demand for respective rooms in houses. The 1652 sampled data obtained in a survey is analyzed using "Dual Sealing" which shizuhiko NIS-HISATO has developed.
