Tong lau


The term tong lau or ke lau is used to describe tenement buildings built in late 19th century to the 1960s in Hong Kong, Taiwan, Southern China and South East Asia. Designed for both residential and commercial uses, they are similar in style and function to the shophouses with five foot way of Southeast Asia. Over the years, tong lau construction has seen influences of Edwardian style architecture and later the Bauhaus movement.

Overview

Tong lau or tang lau means "Chinese building" – Tong or Tang refers to the Tang dynasty and is used as a term to mean Chinese, and lau is a building with more than one floor. It is a general term for a type of building found in Hong Kong that also developed in Macao and Guangzhou from traditional Southern Chinese townhouses. The early buildings were generally long and narrow with width of between 12–15 feet determined by the length of the wooden beams. In Hong Kong's building regulations, it refers a building with any living space intended for more than one tenant. It is essentially a tenement building for residential and commercial use. The ground floor is reserved for commercial use, mostly by small businesses like retail shops and food vendors. The upper floors were residential use and catered to Chinese residents of Hong Kong. Most early tong lau were 2–4 storeys tall because building regulations that initially limited the height of building to 1.25 times the width of the street with a maximum height of 35 feet. However, due to the influx of migrants from mainland China to Hong Kong in the 1950s, height control of buildings was relaxed in 1955, and some tong laus that were built after that may have 9 or more floors, and built without lifts. The heyday of tong lau ended in the 1960s when population pressure resulted in many tong laus being demolished to make way for high-rise buildings and changes in building ordinance that allow for such high-rise buildings.
Ke lau or qilou, is a form of tong lau with an arcade running alongside the road for pedestrian use. The term was originally "qilou with feet", which was first used in Guangzhou's building regulations in 1912, and referred to the columns forming the colonnade that supported the projecting floors that "ride" above. The qilou buildings developed in Guangzhou were influenced by local traditions and the shophouses with five foot ways of Singapore first built under the instructions of Stamford Raffles in his town plan enacted soon after the founding of the colony in the early 19th century. Qilous were built in Southern China starting in the early 20th century. Most of the qilous in Guangzhou were built in the 1930s until the outbreak of the Sino-Japanese war, and few were built after that period.

Early ''tong lau''

The early tong lau in Hong Kong were mainly two- or three-storey structures built back-to-back, and built in areas such as Tai Ping Shan. 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:
in Mong Kok, Hong Kong, was built in 1931.
In 1903, in response to an outbreak of bubonic plague, the Hong Kong government issued a set of new regulations for tong lau so as to improve the living condition of those in these buildings. New tong lau buildings needed to have a light well, have larger windows, and the buildings were limited to four floors so their residents can receive sufficient light. The frontage were set at 15 feet, and at the back there needed to have a 6-foot lane to remove back-to-back constructions. Roof tiles were also replaced by flat concrete roofs.
In the 1920s, reinforced concrete began to be introduced as the main structural element, which allowed for verandah and cantilevered or recessed balconies to let in extra light. An example of early tong lau or Kee-lau is Lui Seng Chun, a building in reinforced concrete built in Hong Kong in 1931.

Post War tong lau

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.
Other features of the new tong lau included:
The post-war boom and influx of immigrants led to a shortage of housing in Hong Kong. Many tong lau were renovated to become rental units. In order to become spacious space, each unit was separated from adjacent units through brick party walls, is between 13 and 16 feet wide.
The ground floor of a tong lau was used as shop space, but a cockloft was often built on the upper space in front of the partition wall of the kitchen, or utilized as working area. Rooms on the upper floors were divided into smaller rooms and sublet as units by owners. They would only accommodate bunk beds. The middle of the floor was common space for tenants to eat and use. Bathrooms and kitchens were also shared amongst the tenants on each floor. Tenants paid for electricity and water on a monthly basis.
The sublet of floors in the tong lau led to changes in housing regulations in Hong Kong.
After the 1960s, many tong lau were demolished to give way to taller apartment and commercial buildings, especially new town or private apartment. Few tong Lau are relatively found in Hong Kong today.
On 29 January 2010, no. 45J Ma Tau Wai Road, Ma Tau Wai, a five-storey tong lau of more than 50 years history, suddenly collapsed at approximately 1:43 pm. Four people were killed. Such spontaneous, cascading and complete building collapse in Hong Kong has been quite rare since the Second World War and the incident raised concern of the HKSAR Government and the Hong Kong public towards the safety of the aging tong lau in Hong Kong, especially those built with similar specifications 50 or more years ago.

Mainland China

Qilou styles varied from Chinese to European:
Southern China, namely cities in Guangdong Province, is where the tong lau and qilou originated. They were built by wealthy Chinese merchants in the cities like Guangzhou and, with the aid of overseas Chinese, in emigrant market towns like Chikan, Kaiping.
Locations in Guangzhou with Qilou:
As both Hainan Island and the eastern part of the Guangxi Province lie in the broader Cantonese sphere of linguistical and cultural influence and historically were part of Guangdong, several cities and towns also have this kind of architecture.

Beihai

The city of Beihai lies on the coast in Guangxi. The Old Sheng Ping Street is lined with qilou architecture. Life and trade thrived here in the 19th century. Today it's full of restaurants, souvenir shops and adorned with sculptures and boards with information about local culture.

Haikou

The historical Bo'ai Road area is located in the heart of the Hainan capital city of Haikou. Nearly all the buildings in this neighbourhood are tong lau style. Beginning around 2012, the entire area has been undergoing restoration. It started with , now completed and converted into a pedestrian zone. The restoration is currently expanding outward with the facades being replastered and painted. Lights facing toward the facades to illuminate them at night are now installed on many of the buildings. With road repair ongoing, and new, tourist-related businesses replacing the old shops, the entire area is being developed as a visitor attraction.

Chengmai

The southern part of the town of Chengmai, located in Chengmai County, has a neighbourhood running along the Nandu River that consists of numerous, dilapidated tong lau buildings.

Wenchang

The tong lau buildings in the city of Wenchang's "Wennan Old Street" have been completely restored. Unlike Haikou's Bo'ai Road area, the facades are unpainted and appear gray in colour. The area is located downtown and is a visitor attraction.
Puqian
An area within the town of Puqian, mostly consisting of a single street, is lined with tong lau buildings. The street is the main route from the port to the town centre. The tong lau buildings are in serious disrepair, many of which are structurally unsafe.

Macau

Tong lau are also found in Macau on Avenida de Almeida Ribeiro near the Largo do Senado. They are better preserved in Macau, where they did not give way to newer buildings. Upper floors no longer house people and often reused for commercial use. tong lau here often feature Portuguese colonial architectural influences.

Hong Kong

The existence of tong laus was a culmination of a series of historic forces from economic development of Hong Kong, Second World War as well as the influx of Chinese migrants to Hong Kong.
In 1898, the government introduced a building and public health ordinance which defined all the buildings including tong laus. In 1903, the government introduced a maximum height per storey of, with a four-storey limit. This explains the general appearance of Tong laus. Yet, the ordinance changed in 1962 which became fully operative in 1966, and no tong lau was built later.
Tong laus are mainly distributed in the following areas in Hong Kong:
