STEP3: DESIGN Along Aberdeen Street, the longitudinal section illustrates a transition from the low-rise tenement houses at mid-level to the high-rise commercial buildings towards Central. Both vehicular and pedestrian traffics are fighting for space, yet between buildings there are narrow in-between spaces for informal expressions of urban life, some traditional, some contemporary. Hawkers, street-corner barbershops, informal settlements,… are composing the unique character of Hong Kong streets. To discover and reinvent this kind of vernacular architecture will request a critical eye from how spaces are ‘shared’, ‘borrowed’ and ‘occupied’ with the public domain, thus a room truly interacting with the city.
