Qilou

The term tong lau or qi lou (Chinese: 唐樓 / 騎樓) is used to describe tenement buildings built in late 19th century to the 1960s in Hong Kong, Macau, southern China and Taiwan. Designed for both residential and commercial uses, they are similar in style and function to the shophouses of Southeast Asia.

Tong lau is essentially a balcony-type tenement building for residential and commercial use. The ground floor portion is reserved for commercial use, mostly by small businesses like pawnshops and food vendors. The upper floors were residential use and catered to Chinese residents of Hong Kong. Most tong lau were 2–4 storeys tall and 15 feet (4.5 m) in width.

19th century tong lau encompassed Chinese and European architectural features. The Chinese component was based on building design from southern China, mainly in Guangdong Province. European influences were usually Neoclassical.

The tong lau roof used wood and/or Xieding tiles and iron was used for the balconies. The balcony's design was based on Cantonese styles. Windows used French styling and were made of wood and glass.

The upper floors were supported by brick pillars and protruded out to the edge of the street.

Inside, the floors were connected by wooden stairs. Most floors ranged from 450–700 square feet with very high ceilings. Top floors were often living quarters for shopkeepers and their family.

Other architectural features of early tong laus:

An example of early tong lau or Kee-lau is Lui Seng Chun, a reinforced concrete building built in Hong Kong in 1931.

Tong lau built after World War II were simpler in design:

Iron balconies were replaced with concrete ones and later sealed with windows. Roofs were often flat with an open terrace and later renovated to allow for additional residential space.

Wooden windows gave way to stainless steel windows. Air conditioning units were added to the windows in the 1970s and 1980s. Often clothes racks were added below the windows and hung above the sidewalk or street below. Signs were hung on the exterior walls and protruded onto the streets below.
