A space becomes familiar through inhabitation. This thesis constructs an urban dwelling unit through memory, sensory thresholds, time, and accumulation, operating within a fixed architectural shell. As a Lebanese living in Los Angeles, the design adapts with hyper-specificity to the occupier, shaping how one cooks, rests, arrives, and gathers daily. Framed as a gesamtkunstwerk, each element produces experience rather than representing it. The project follows a system of five rules that act on edges, thresholds, and surfaces to continuously reshape the space. The dwelling operates as a process, shifting toward an ongoing state of becoming familiar.
