INDIAN ARCHITECTURE

Architecture of India
The architecture of India is rooted in its history, culture and religion. Indian architecture progressed with time and assimilated the many influences that came as a result of India's global discourse with other regions of the world throughout its millennia-old past.The architectural methods practiced in India are a result of examination and implementation of its established building traditions and outside cultural interactions.
Though old, this Eastern tradition has also incorporated modern values as India became a modern nation state.The economic reforms of 1991 further bolstered the urban architecture of India as the country became more integrated with the world's economy.Traditional Vastu Shastra remains influential in India's architecture during the contemporary era.

ACHITECTURE IN THE POST COLONIAL PERIOD:

In recent times there has been a movement of population from rural areas to urban centres of industry, leading to price rise in property in various cities of India.Urban housing in India balances space constrictions and is aimed to serve the working class.Indian government has accepted World Trade Organisation’s General Agreement on Trade in Services (GATS), enabling foreign architects to practice in India, and thereby adding to the plurality of Indian building traditions.Growing awareness of ecology has influenced architecture in India during modern times.

Indian buildings reflect India's culture and myths.Jawahar Kala Kendra at Jaipur, a Charles Correa design for example represents the layout of a mandala.Raj Jadhav (2007) notes the position of traditional Vastu Shastra in modern Indian architecture.

The ancient Indian architectural text of Vastu Shastra is widely used in modern Indian architecture for planning houses, residential complexes, office, commercial, industrial and other building types. The principles of Vastu Shastra regulate planning and design specifics from town planning to the furniture layout of a room. The stipulations are said to be governed by ancient empirical knowledge of the human body and its relation to the earth and the cosmos. Following these stipulations, it is said, ensures overall human well-being. Hence, a client with a belief in Vastu Shastra will choose a plot of land and locate the functions and elements of a building using the guidelines of this text. Architects and clients consult specialists in Vastu Shastra and then agree upon a design. The belief in this ancient body of knowledge is experiencing a rapid revival.

The courtyards also take up an old Indian architectural motif whereby the courtyard provides light and air for the rooms directly in this hot climate, and people are able to spend time outside or inside according to the time of day. The courtyard is also the classical symbol of something shared, a place where people meet, spend time with each other and live together. This aspect is emphasised in the courtyard for the general public, which is placed immediately inside the entrance and constructed in the form of a Kund, a large area of stone steps. Here people spend their waiting time together almost as if in a state of communal meditation. A waiting area that would be completely inconceivable in Western culture functions as a “think tank” here, with the ambience of waiting stimulating communal reflection.

VERNACULAR ARCHITECTURE

Vernacular architecture is a term used to categorise methods of construction which use locally available resources and traditions to address local needs. Vernacular architecture tends to evolve over time to reflect the environmental, cultural and historical context in which it exists. It has often been dismissed as crude and unrefined, but also has proponents who highlight its importance in current design.

It 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.
A "Plantation Cottage" style building on the island of Kauai, Hawaii. This is a vernacular architecture style developed in Hawaii in the epoch of sugar cane plantations.
Stone and clay houses in rural NepalThe building knowledge in vernacular architecture is often transported by local traditions and is thus based largely - but not only - upon knowledge achieved by trial and error and handed down through the generations, in contrast to the geometrical and physical calculations that underlie architecture planned by architects. This of course does not prevent architects from using vernacular architecture in their designs or from being firmly based in the vernacular architecture of their regions.

DEFINITIONS:
.W. 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 consderations, 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 term is not to be confused with so-called "traditional" architecture, though there are links between the two. Traditional architecture can also include 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 and the architect
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.

Oliver also offers the following simple definition of vernacular architecture:

the architecture of the people, and by the people, but not for the people.

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
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.
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.
Modern proponents of the use of the vernacular in architectural design include Charles Correa, a well known Indian architect, and Balkrishna Doshi, also Indian, who established the Vastu-Shilpa Foundation in Ahmedabad to research the vernacular architecture of the region. The Dutch architect Aldo van Eyck was also a proponent of vernacular architecture. Architects whose work exemplifies the modern take on vernacular architecture would be Samuel Mockbee, Christopher Alexander and Paolo Soleri.
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.


Influences on the vernacular
European influenced log cabin in Bariloche (Patagonia), Argentina. To comply with strict local building codes, every piece of wood cut down from the property must be accounted for in the building of the cabin and related infrastructure, and the same number of trees must be replanted in the vicinity.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.

Climate
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.

Culture
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 tribes 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 tribes 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.

Nomadic dwellings
Stilt houses in Cempa, located in the Lingga Islands of Indonesia.
A Yurt or ger, a circular dwelling from Mongolia during erection
An Igloo, an Inuit winter dwellingThere 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, and if necessary, transport.
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 tent (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, including the atnaris-kahte tent. 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 yurts or gers with them, or the black desert tents of the Qashgai in Iran.[9] Notable in each case is the signicant 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 will be adapted to suit the local climate. The Mongolian gers, 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 closable 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.



Permanent dwellings
A Southern African rondavel (or banda)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.

Environment and materials
The local environment and the construction materials it can provide governs many aspect of vernacular architecture. Areas rich in trees will develop a wooden vernacular, while areas without much wood may use mud or stone. 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.

Humanitarian response
"Sutyagin House", world's tallest wooden single-family house - declared illegal by the city of Arkhangelsk because of the fire hazardAn 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.

Legal aspects
As many jurisdictions introduce tougher building codes and zoning regulations, "folk architects" sometimes find themselves in conflict with the local authorities. A case that made news in Russia was that of an Arkhangelsk entrepreneur Nikolay P. Sutyagin, who built the reportedly world's tallest single-family wooden house for himself and his family - only to be condemned as a fire hazard. The 13-story, 144-ft tall structure, known locally as "Sutyagin's skyscraper" is currently awaiting demolition, which, according to a court decision, has to take place by February 1, 2009.

STRUCTURALISM IN ARCHITECTURE


Structuralism as a movement in architecture and urban planning evolved around the middle of the 20th century. It was a reaction to Congrès International d'Architecture Moderne(or International Congress of Modern Architecture),CIAM-Functionalism (Rationalism), which had led to a lifeless expression of urban planning that ignored the identity of the inhabitants and urban forms.
Two different manifestations of Structuralist architecture exist. Sometimes these occur in combination with each other. On the one hand, there is the Aesthetics of Number, formulated by Aldo van Eyck. This concept can be compared to cellular tissue. On the other hand, there is the Architecture of Lively Variety, formulated by John Habraken. This second concept is related to user participation in housing.
The "Aesthetics of Number" can also be described as "Spatial Configurations in Architecture", and the "Architecture of Lively Variety" as "Architecture of Diversity" or "Pluralistic Architecture".

Structuralism in architecture and urban planning had its origins in the Congrès International d'Architecture Moderne (CIAM) after World War II. Between 1928 and 1959, the CIAM was an important platform for the discussion of architecture and urbanism. Various groups with often conflicting views were active in this organization; for example, members with a scientific approach to architecture without aesthetic premises (Rationalists), members who regarded architecture as an art form (Le Corbusier), members who were proponents of high- or low-rise building (Ernst May), members supporting a course of reform after World War II (Team 10), members of the old guard and so on.

Individual members of the small splinter group Team 10 laid the foundations for Structuralism. The influence of this team was later interpreted by second generation protagonist Herman Hertzberger when he said: "I am a product of Team 10." As a group, Team 10 was active from 1953 onwards, and two different movements emerged from it: the New Brutalism of the English members (Alison and Peter Smithson) and the Structuralism of the Dutch members (Aldo van Eyck and Jacob Bakema).

Outside Team 10, other ideas developed that furthered the Structuralist movement - influenced by the concepts of Louis Kahn in the United States, Kenzo Tange in Japan and John Habraken in the Netherlands (with his theory of user participation in housing). Herman Hertzberger and Lucien Kroll made important architectural contributions in the field of participation. In this context, Hertzberger made the following statement: "In Structuralism, one differentiates between a structure with a long life cycle and infills with shorter life cycles."

In 1960, the Japanese architect Kenzo Tange designed his well-known Tokyo Bay Plan. Reflecting later on the initial phase of that project, he said: "It was, I believe, around 1959 or at the beginning of the sixties that I began to think about what I was later to call Structuralism", (cited in Plan 2/1982, Amsterdam). Tange also wrote the article "Function, Structure and Symbol, 1966", in which he describes the transition from a functional to a structural approach in thinking. Tange considers the period from 1920 to 1960 under the heading of "Functionalism" and the time from 1960 onwards under the heading of "Structuralism".

Le Corbusier created several early projects and built prototypes in a Structuralist mode, some of them dating back to the 1920s. Although he was criticized by the members of Team 10 in the 1950s for certain aspects of his work (urban concept without a "sense of place" and the dark interior streets of the Unité), they nevertheless acknowledged him as a great model and creative personality in architecture and art.
