I wanted to create ambulatory freedom in the space of a small housing unit. Therefore, I dwell on the ambiguity between transparency and opaqueness as primary references in terms of spatial configuration and circulation. The layout of one living- and one bedroom also accommodate the dining space, kitchen, changing room, and bathroom, all linked together without divisions except for the sliding doors in the bedroom and bathroom. The glass brick wall is used as the center to connect the hallway, living room, kitchen, and bedroom.
