Built in the 1960s as a new generation of wet market, the two-tone Tang Lung Chau is another classic example of functionalist architecture in Hong Kong.  The design for each face of the rectangular concrete structure varies to suit its function and to create a subtle dynamic.  The east-facing façade is built with deeper grid-shaped brise-soleil.  The north-facing facade and the south-facing facade of the buildings have small windows on the side and a large perforated wall to balance the bulky structure with a soft and airy touch.  The lattice wall design also allows daylight to pass through the wall as well as to let indoor light be visible from the outside at night. When the project was assigned in the 1960s, one of the requirements was to separate delivery and vendor’s circulation space from the main market’s trading space.  Creating a “backstage area” in a relatively small and congested space isn’t an easy task. The designer successfully hid a few service passages behind from the stalls on the sides of the market.  These service passages are connected with dedicated service lifts, platforms, unloading areas and entrances that suit the needs for different vendors.
