By comparing the above examples, we can have a rough idea of what vernacular architecture means. Usually, buildings designed by professional architects are not considered vernacular.

7 By comparing the above examples, we can have a rough idea of what vernacular architecture means. Usually, buildings designed by professional architects are not considered vernacular. Some would simply define vernacular architecture as architecture without architects. American Architect Frank Lloyd Wright defined vernacular architecture as folk building growing in response to actual needs, fitted into the environment by people who knew no better than to fit them with native feeling. Characteristics of vernacular architecture are as below: Use of traditional or locally available construction skills Use of simple technology and commonly available materials New structure with old techniques as experiment and innovation are more costly than repetition Evolved slowly through numerous experimental trials and errors instead of specifically designed by a professional Functionalistic and simple design which fulfils basic needs of the people Born of people s needs, culture, tradition and adapted to local climate Teaching Tips Vernacular architecture is an example of Hong Kong s local culture. For further information, please refer to Topic 03: Globalization and Localization of Architecture and Urban Planning. The stilt houses in Ma Wan are examples of vernacular architecture. They were not designed by architects, but instead were developed slowly through time by the local people to adapt to the environment and their living style, and were built with the most handy materials. 04

8 1.2 Case Studies: Various Cultures in Vernacular Architecture of Hong Kong A series of Tong Lau at Shanghai Street Tong Lau or Tenement Houses - architecture for a dense population What is Tong Lau? The history of tenement houses or Tong Lau ( 唐樓 ) dates back to the mid-19 th century. The ground floor of a tenement house is occupied by a shop while the mezzanine and other storeys are for living. Multiple tenants usually shared one flat due to the shortage of living space at the time. Eventually this grew to be one of the most common building types in Hong Kong, South China and Southeast Asia, with particular stylistic flourishes in each place. Why were Tong Lau developed? When Hong Kong became a British colony in 1842, a large number of Chinese from China s coastal cities moved to this politically stable colonial city in search of better lives, causing a serious shortage of housing. On the other hand, the establishment of Victoria City ( 維多利亞城 ), the area around Central today, required cheap labour which could be fulfilled by the influx of Chinese immigrants. Chinese workers began to settle in Sheung Wan, the periphery of Victoria City. Borrowing the architectural style from South China, Tong Lau was the quick and convenient answer to the housing problem. 05

Early Tong Laus were long and narrow, accessed by a long, dark staircase without any natural lighting and ventilation. There was also no provision of elevators and toilets which explained the need for the collection of night soil ( 倒夜香 ) in the past. What is the architectural style of Tong Lau? Although Hong Kong Tong Laus resemble the other tenement buildings in South China, they are unique in their details which display a mix of Chinese and Western styles. Very often, Tong Laus have balconies or verandahs which project over the pedestrian pavement.

11 Effects of building design on lives of people To accommodate different families resulted from the influx of immigrant workers, each flat was divided into front room, middle room, end room (Fig. 1) or even smaller cubicles. Sometimes the roof and the attic above the kitchen would be rented out too. The front room was the only room open to fresh air and natural light, and would usually be occupied by the landlord, the only person who could afford the rent. Rooms were separated by partitions which were built lower than the ceiling height to leave a gap for ventilation since there was no window in the whole flat except at the front of the building. As partitions were thin and without any soundproofing, privacy was a critical issue. Hygiene condition was also poor as all tenants had to share the only bathroom and kitchen.

12 What are the problems in early Tong Laus In the early days of Tong Lau, there was no regulation on its design. The buildings were tightly packed, built side to side and back to back without any space for natural ventilation and light could not penetrate into the interior and the building blocks were long and narrow (Fig. 1). How did the government regulate the Tong Laus design? Prompted by the outbreak of bubonic plague in the overcrowded tenement block quarters around Tai Ping Shan Street, Sheung Wan in 1894, the government finally implemented the first buildings control under the Public Healthy and Buildings Ordinance in 1903 to regulate the design of Tong Laus in order to ensure the quality of construction and living space. 1. Improvement of Tong Laus A back lane and open space had to be provided, which means that more space had to left between buildings. Building height was restricted to the width of the street it was facing to ensure enough daylight penetrate, and building depth was limited to 12m to improve natural lighting condition of the interior. 2. Official Buildings regulation on Tong Laus The statutory regulation over Tong Lau design was further strengthened with the Buildings Ordinance Allowable building depth was further reduced to 11m. Adequate light and ventilation was to be provided at every storey on every staircase, hence caused the emergence of a new type of Tong Lau with a naturally lit and ventilated common staircase (Fig. 2).

13 1.2.2 Stilt Houses - architecture for a traditional lifestyle What is stilt house? Stilt houses, a type of housing elevated above the water on stilts, can be found in fishing villages of Tai O and Ma Wan. They were built by the Tanka, a group of people who have lived in South China provinces including Guangdong and Fujian for centuries, and they were also one of the earliest habitants in Hong Kong. This building typology has gone through a long evolution to suit the habits and lifestyle of its creator. Why did the Tanka people build stilt houses? The Tanka people live on boats and rely mainly on fishing and salt production for a living. There is no standard definition of what ethnicity the Tanka is. It is however believed that they were a mix of Han and other southern races who fled to the sea due to war or exile. The stilt house typology in Tai O was gradually developed around 200 years ago when the Tai O Tanka people moved into houses as family sizes grew too big to be accommodated by the traditional boathouses. How were stilt houses built? The earliest stilt houses were constructed in a barrelshape resembling a boat with wooden planks, stone stilts and palm leaves, while later houses were made of metal sheeting, wooden planks and stilts. The barrel form was taken over by the pitched roof and houses expanded from one-storey to two-storey high. Local residents found the earliest structures were not strong enough. The stone pillars collapse easily and the p Stilt houses in Tai O. Note the pitched roofs, the multiuse wooden decks and access to boats by ladders p Lives of people in the 1960s, before the fire in 2000 whole structure would shift away during serious floods. In the 50s, Tai O locals began to take wood from disused fishing boats for the construction of stilt houses. This reddish brown ironwood ( 坤甸木 ) from South China is strong and resistant to water erosion, and therefore widely used in boat making. Villagers found it to be the perfect material for the local environment. After a devastating fire in 2000, Tai O saw the birth of a new type of stilt house. New materials including plaster and aluminium sheets were used. 10

Facilities such the kitchens and the shared bathrooms are placed along this axis. The house at the end of the walkway and right above the water is built with a wooden deck. Fishing boats are tied right underneath and are easily accessible by a ladder which stretches from the deck to the water. 2. Constructural improvement An early vaulted stilt house is divided into two rooms while a newer house has 3 compartments on the ground floor and bedrooms on the upper floor. Cross bracing was also used to improve structural stability of the stilt supports. 3. Reconstruction of the vernacular village After the fire in 2000, affected residents were allowed to rebuild their houses. Despite the need to apply for reconstruction licence and to comply to fire safety requirements, the reconstruction process was organic and flexible as typical in vernacular architecture. The residents communicated closely with the builders, and the resulting new houses were all customised to the owners needs. 1&2: An early vaulted stilt house on concrete supports and a close up view of a vaulted roof.

The deck is where the family gathers, prepare for work and for meals, as well as to relax. How do stilt houses adapt to lifestyle and needs? 1. Terrace The terrace side facing the water is regarded as the front/ head ( 棚頭 ) of the stilt house. As there was insufficient electricity supply in the past, a lot of activities such as drying of salted fish, net knitting and cooking were conducted under the sun and such outdoor space was important. As the fishing industry diminished, families and young people would still enjoy barbecue on the deck while older people dry salted fish, salted egg yolks and shrimps in the sun. 2. Personal taste of architectural design When residents rebuilt the houses that were lost in the fire of 2000, they worked closely with the builders to make sure the new houses suit their individual needs. For example, Mr. Wong wanted to explore new methods of construction, and so he used red roof tiles instead of the traditional metal sheeting. Mr. Fan, who owned a salted fish shop, was allowed to build a larger platform for producing salted fish. Another Mr. Wong, who was a painter, decided to incorporate a double-volume space with a skylight to be his studio. These examples show how dynamic architecture can be. Such interaction, flexibility, adaptation according to needs, environmental condition and resources are all essential elements in vernacular architecture which modern, professionally designed architecture often lacks. 13

17 Walled Village - architecture for defence What is walled village? Early residents of the New Territories were mainly farmers from South China. In an agricultural society, people lived with their own clan ( 氏 ) in a cluster of farm houses in South China architectural style. The main entrance, assembly hall and the ancestral hall aligns to a central axis. As the clan expanded, side houses were built around the older houses but the symmetrical layout was retained. Between the houses were courtyards and lanes for circulation and which also allowed natural ventilation in the hot wet climate of Hong Kong. Some walled villages even have watch towers at the corners and moats around the wall. Why were walled villages developed? The history of Hong Kong s walled village dates back to Ming and Qing dynasties. There are 2 types of walled villages - the Punti ( 本地 ) and the Hakka ( 客家 ). In Ming and Qing dynasties, Punti villagers began to build walls around their houses to protect themselves from pirates attack. In late Qing, Hakka people began to settle in the New Territories. Due to their different culture, language and customs, they also built walls to protect the village against rival clans. How were walled villages built? Houses in a walled village were constructed with traditional materials such as stone, bricks, timber and Chinese tiles. Strong metal gates and wooden shutters were installed at the main entrances. p Wooden shutter for security p The watch tower at the corner of Shan Ha Wai (also known as Tsang Tai Uk) ( 山下圍, 又稱曾大屋 ), Shatin.

21 Summary Vernacular buildings are designed by everyday people who use and live in them. The building methods and designs have gone through a long process of evolution in response to culture, climate and technology. The Tong Lau / tenement house is a building type popular in South China from late 19 th century to 1960s. The ground floor of a Tong Lau is occupied by a shop while the other stories are residential flats. A stilt house is a building type created by the Tanka people who rely mainly on fishing for their livelihood. The house is made of wood with metal sheeting, and is supported above the water by wooden stilts. Walled villages are found throughout Southern China. They are formed of a group of houses enclosed by a protective wall, and were usually built by Hakka or Punti farmers.
