It tends to evolve over time to reflect the environmental, cultural, technological, and historical context in which it exists. While often not thoroughly and academically planned, this kind of architecture played and still plays a major role in the history of architecture and design, especially in local branches.
Vernacular architecture can be contrasted against polite architecture which is characterised by stylistic elements of design intentionally incorporated for aesthetic purposes which go beyond a building's functional requirements. For the similarities to "traditional architecture" see below.
The term vernacular is derived from the Latin vernaculus, meaning "domestic, native, indigenous"; from verna, meaning "native slave" or "home-born slave". The word probably derives from an older Etruscan word.
In linguistics, vernacular refers to language use particular to a time, place or group. In architecture, it refers to that type of architecture which is indigenous to a specific time or place (not imported or copied from elsewhere). It is most often applied to residential buildings.
The terms vernacular, folk, traditional, and popular architecture are sometimes used synonymously. However, Allen Noble wrote a lengthy discussion of these terms in Traditional Buildings: A Global Survey of Structural Forms and Cultural Functions where he presents scholarly opinions that folk building or folk architecture is built by "...persons not professionally trained in building arts..."; where vernacular architecture is still of the common people but may be built by trained professionals such as through an apprenticeship, but still using local, traditional designs and materials. Traditional architecture is architecture is passed down from person to person, generation to generation, particularly orally, but at any level of society, not just by common people. Noble discourages use of the term primitive architecture as having a negative connotation. The term popular architecture is used more in eastern Europe and is synonymous with folk or vernacular architecture.
Ronald Brunskill has defined the ultimate in vernacular architecture as:
...a building designed by an amateur without any training in design; the individual will have been guided by a series of conventions built up in his locality, paying little attention to what may be fashionable. The function of the building would be the dominant factor, aesthetic considerations, though present to some small degree, being quite minimal. Local materials would be used as a matter of course, other materials being chosen and imported quite exceptionally.
The vernacular architecture is not to be confused with so-called "traditional" architecture, though there are links between the two. Traditional architecture also includes buildings which bear elements of polite design: temples and palaces, for example, which normally would not be included under the rubric of "vernacular." In architectural terms, 'the vernacular' can be contrasted with 'the polite', which is characterised by stylistic elements of design intentionally incorporated by a professional architect for aesthetic purposes which go beyond a building's functional requirements. Between the extremes of the wholly vernacular and the completely polite, examples occur which have some vernacular and some polite content, often making the differences between the vernacular and the polite a matter of degree.
The Encyclopedia of Vernacular Architecture of the World defines vernacular architecture as:
...comprising the dwellings and all other buildings of the people. Related to their environmental contexts and available resources they are customarily owner- or community-built, utilizing traditional technologies. All forms of vernacular architecture are built to meet specific needs, accommodating the values, economies and ways of life of the cultures that produce them.
Vernacular architecture is a broad, grassroots concept which encompasses fields of architectural study including aboriginal, indigenous, ancestral, rural, and ethnic architecture and is contrasted with the more intellectual architecture called polite, formal, or academic architecture just as folk art is contrasted with fine art.
Architecture designed by professional architects is usually not considered to be vernacular. Indeed, it can be argued that the very process of consciously designing a building makes it not vernacular. Paul Oliver, in his book Dwellings, states: "...it is contended that 'popular architecture' designed by professional architects or commercial builders for popular use, does not come within the compass of the vernacular".:15 Oliver also offers the following simple definition of vernacular architecture: "the architecture of the people, and by the people, but not for the people.":14
Frank Lloyd Wright described vernacular architecture as "Folk building growing in response to actual needs, fitted into environment by people who knew no better than to fit them with native feeling".:9 suggesting that it is a primitive form of design, lacking intelligent thought, but he also stated that it was "for us better worth study than all the highly self-conscious academic attempts at the beautiful throughout Europe".
Many modern architects have studied vernacular buildings and claimed to draw inspiration from them, including aspects of the vernacular in their designs. In 1946, the Egyptian architect Hassan Fathy was appointed to design the town of New Gourna near Luxor. Having studied traditional Nubian settlements and technologies, he incorporated the traditional mud brick vaults of the Nubian settlements in his designs. The experiment failed, due to a variety of social and economic reasons, but is the first recorded attempt by an architect to address the social and environmental requirements of building users by adopting the methods and forms of the vernacular.:11
In 1964 the exhibition Architecture Without Architects was put on at the Museum of Modern Art, New York by Bernard Rudofsky. Accompanied by a book of the same title, including black-and-white photography of vernacular buildings around the world, the exhibition was extremely popular. It was Rudofsky who first made use of the term vernacular in an architectural context, and brought the concept into the eye of the public and of mainstream architecture: "For want of a generic label we shall call it vernacular, anonymous, spontaneous, indigenous, rural, as the case may be."
Since the emergence of the term in the 1970s, vernacular considerations have played an increasing part in architectural designs, although individual architects had widely varying opinions of the merits of the vernacular.
Sri Lankan architect Geoffrey Bawa is considered the pioneer of regional modernism in South Asia. Along with him, modern proponents of the use of the vernacular in architectural design include Charles Correa, a well known Indian architect; Muzharul Islam and Bashirul Haq, internationally known Bangladeshi architects; Balkrishna Doshi, another Indian, who established the Vastu-Shilpa Foundation in Ahmedabad to research the vernacular architecture of the region; and Sheila Sri Prakash who has used rural Indian architecture as an inspiration for innovations in environmental and socio-economically sustainable design and planning. The Dutch architect Aldo van Eyck was also a proponent of vernacular architecture.:13 Architects whose work exemplifies the modern take on vernacular architecture would be Samuel Mockbee, Christopher Alexander and Paolo Soleri.
Oliver claims that:
As yet there is no clearly defined and specialized discipline for the study of dwellings or the larger compass of vernacular architecture. If such a discipline were to emerge it would probably be one that combines some of the elements of both architecture and anthropology with aspects of history and geography[clarification needed]
Vernacular architecture is influenced by a great range of different aspects of human behaviour and environment, leading to differing building forms for almost every different context; even neighbouring villages may have subtly different approaches to the construction and use of their dwellings, even if they at first appear the same. Despite these variations, every building is subject to the same laws of physics, and hence will demonstrate significant similarities in structural forms.
One of the most significant influences on vernacular architecture is the macro climate of the area in which the building is constructed. Buildings in cold climates invariably have high thermal mass or significant amounts of insulation. They are usually sealed in order to prevent heat loss, and openings such as windows tend to be small or non-existent. Buildings in warm climates, by contrast, tend to be constructed of lighter materials and to allow significant cross-ventilation through openings in the fabric of the building.
Buildings for a continental climate must be able to cope with significant variations in temperature, and may even be altered by their occupants according to the seasons.
Buildings take different forms depending on precipitation levels in the region – leading to dwellings on stilts in many regions with frequent flooding or rainy monsoon seasons. Flat roofs are rare in areas with high levels of precipitation. Similarly, areas with high winds will lead to specialised buildings able to cope with them, and buildings will be oriented to present minimal area to the direction of prevailing winds.
Climatic influences on vernacular architecture are substantial and can be extremely complex. Mediterranean vernacular, and that of much of the Middle East, often includes a courtyard with a fountain or pond; air cooled by water mist and evaporation is drawn through the building by the natural ventilation set up by the building form. Similarly, Northern African vernacular often has very high thermal mass and small windows to keep the occupants cool, and in many cases also includes chimneys, not for fires but to draw air through the internal spaces. Such specialisations are not designed, but learnt by trial and error over generations of building construction, often existing long before the scientific theories which explain why they work.
The way of life of building occupants, and the way they use their shelters, is of great influence on building forms. The size of family units, who shares which spaces, how food is prepared and eaten, how people interact and many other cultural considerations will affect the layout and size of dwellings.
For example, the family units of several East African ethnic communities live in family compounds, surrounded by marked boundaries, in which separate single-roomed dwellings are built to house different members of the family. In polygamous communities there may be separate dwellings for different wives, and more again for sons who are too old to share space with the women of the family. Social interaction within the family is governed by, and privacy is provided by, the separation between the structures in which family members live. By contrast, in Western Europe, such separation is accomplished inside one dwelling, by dividing the building into separate rooms.
Culture also has a great influence on the appearance of vernacular buildings, as occupants often decorate buildings in accordance with local customs and beliefs.
There are many cultures around the world which include some aspect of nomadic life, and they have all developed vernacular solutions for the need for shelter. These all include appropriate responses to climate and customs of their inhabitants, including practicalities of simple construction such as huts, and if necessary, transport such as tents.
The Inuit people have a number of different forms of shelter appropriate to different seasons and geographical locations, including the igloo (for winter) and the tupiq (for summer). The Sami of Northern Europe, who live in climates similar to those experienced by the Inuit, have developed different shelters appropriate to their culture:25 including the lavvu and goahti. The development of different solutions in similar circumstances because of cultural influences is typical of vernacular architecture.
Many nomadic people use materials common in the local environment to construct temporary dwellings, such as the Punan of Sarawak who use palm fronds, or the Ituri Pygmies who use saplings and mongongo leaves to construct domed huts. Other cultures reuse materials, transporting them with them as they move. Examples of this are the tribes of Mongolia, who carry their gers (yurts) with them, or the black desert tents of the Qashgai in Iran.:29 Notable in each case is the significant impact of the availability of materials and the availability of pack animals or other forms of transport on the ultimate form of the shelters.
All the shelters are adapted to suit the local climate. The Mongolian gers (yurts), for example, are versatile enough to be cool in hot continental summers and warm in the sub-zero temperaturs of Mongolian winters, and include a close-able ventilation hole at the centre and a chimney for a stove. A ger is typically not often relocated, and is therefore sturdy and secure, including wooden front door and several layers of coverings. A berber tent, by contrast, might be relocated daily, and is much lighter and quicker to erect and dismantle – and because of the climate it is used in, does not need to provide the same degree of protection from the elements.
In transhumance (the seasonal movement of people with their livestock to pasture) the herders stay in huts or tents.
The type of structure and materials used for a dwelling vary depending on how permanent it is. Frequently moved nomadic structures will be lightweight and simple, more permanent ones will be less so. When people settle somewhere permanently, the architecture of their dwellings will change to reflect that.
Materials used will become heavier, more solid and more durable. They may also become more complicated and more expensive, as the capital and labour required to construct them is a one-time cost. Permanent dwellings often offer a greater degree of protection and shelter from the elements. In some cases however, where dwellings are subjected to severe weather conditions such as frequent flooding or high winds, buildings may be deliberately "designed" to fail and be replaced, rather than requiring the uneconomical or even impossible structures needed to withstand them. The collapse of a relatively flimsy, lightweight structure is also less likely to cause serious injury than a heavy structure.
Over time, dwellings' architecture may come to reflect a very specific geographical locale.
The local environment and the construction materials it can provide, govern many aspects of vernacular architecture. Areas rich in trees will develop a wooden vernacular, while areas without much wood may use mud or stone. In early California redwood water towers supporting redwood tanks and enclosed by redwood siding (tankhouses) were part of a self-contained wind-powered domestic water system. In the Far East it is common to use bamboo, as it is both plentiful and versatile. Vernacular, almost by definition, is sustainable, and will not exhaust the local resources. If it is not sustainable, it is not suitable for its local context, and cannot be vernacular.
Following the eclipse by International Modernism of turn-of-the 20th century vernacular-inspired British and American Arts and Crafts buildings and European National Romanticism, an early work in the renewed defense of vernacular was Bernard Rudofsky's 1964 book Architecture Without Architects: a short introduction to non-pedigreed architecture, based on his MoMA exhibition. The book was a reminder of the legitimacy and "hard-won knowledge" inherent in vernacular buildings, from Polish salt-caves to gigantic Syrian water wheels to Moroccan desert fortresses, and was considered iconoclastic at the time. Rudofsky was, however, very much a Romantic who viewed native populations in a historical bubble of contentment. Rudofsky's book was also based largely on photographs and not on on-site study.
A more nuanced work is the Encyclopedia of Vernacular Architecture of the World edited in 1997 by Paul Oliver of the Oxford Institute for Sustainable Development. Oliver argues that vernacular architecture, given the insights it gives into issues of environmental adaptation, will be necessary in the future to "ensure sustainability in both cultural and economic terms beyond the short term." Christopher Alexander, in his book A Pattern Language, attempted to identify adaptive features of traditional architecture that apply across cultures. Howard Davis's book The Culture of Building details the culture that enabled several vernacular traditions.
Some extend the term vernacular to include any architecture outside the academic mainstream. The term "commercial vernacular", popularized in the late 1960s by the publication of Robert Venturi's "Learning from Las Vegas", refers to 20th-century American suburban tract and commercial architecture. There is also the concept of an "industrial vernacular" with its emphasis on the aesthetics of shops, garages and factories. Some have linked vernacular with "off-the-shelf" aesthetics. In any respect, those who study these types of vernaculars hold that the low-end characteristics of this aesthetic define a useful and fundamental approach to architectural design.
Among those who study vernacular architecture are those who are interested in the question of everyday life and those lean toward questions of sociology. In this, many were influenced by The Practice of Everyday Life (1974) by Michel de Certeau.
An appreciation of vernacular architecture is increasingly seen as vital in the immediate response to disasters and the following construction of transitional shelter if it is needed. The work Transitional Settlement: Displaced Populations, produced by Shelter Centre covers the use of vernacular in humanitarian response and argues its importance.
The value of housing displaced people in shelters which are in some way familiar is seen to provide reassurance and comfort following often very traumatic times. As the needs change from saving lives to providing medium to long term shelter the construction of locally appropriate and accepted housing can be very important.
A case that made news in Russia was that of an Arkhangelsk entrepreneur Nikolay P. Sutyagin, who built what was reportedly the world's tallest single-family wooden house for himself and his family, only to see it condemned as a fire hazard. The 13-storey, 144 feet (44 m) tall structure, known locally as "Sutyagin's skyscraper" (Небоскрёб Сутягина), was found to be in violation of Arkhangelsk building codes, and in 2008 the courts ordered the building to be demolished by February 1, 2009. On December 26, 2008, the tower was pulled down, and the remainder was dismantled manually over the course of the next several months.

Different regions in Ukraine have their own distinctive style of vernacular architecture. For example, in the Carpathian Mountains and the surrounding foothills, wood and clay are the primary traditional building materials. Ukrainian architecture is preserved at The Museum of Folk Architecture and Way of Life of Central Naddnipryanshchyna located in Pereiaslav-Khmelnytskyi, Ukraine.
