The modern theories of tactile/haptic perception, particularly those articulated by Alois Riegl and Walter Benjamin, provides us with unique and often contrasting insights into the perception of space in architecture. Through the lenses of these theories, this study aims to analyse and compare two modern methods of space configuration, namely, Adolf Loos' 'Raumplan' and Le Corbusier's 'Plan Libre'. Riegl's conception of tactile/haptic space helps us identify 'Raumplan's essential theme, i. e., space as a clear-and-distinct three-dimensional entity with 'material individuality', while Benjamin's conception of tactile/haptic movement aids us in identifying 'Plan Libre's essential theme, i. e., space as an open continuum in which fragmented perception is allowed for the moving subject. ............................................................................................................................................. 키워드 : 촉각성, 공간, 운동, ‘라움플란’, ‘자유평면’
