In this paper, the effect of lighting irradiation angle on the visual evaluation of building stone finishing was investigated. The factors affecting the visual evaluation such as unevenness, roughness, glossiness, naturalness, comfort, feature and complexity of stone surface were analyzed by performing the sensory test using the natural sandstone specimen which were changing the stone type, surface finishing method and surface pattern. In the sensory test, lighting irradiation angle(θ) for the stone surface was changed. The relationships between θ and the sensory values were considered. It was cleared that the visual evaluation of sandstone specimen was affected by the lighting irradiation angle in the visual evaluation such as unevenness and roughness, a glossy specimen have a tendency to the smaller the angle, the more marked the effect became, physical surface roughness was related to the visual evaluation of roughness and complexity under 45 degrees of lighting irradiation angle.
