Architect Training Modules

The Ingredients of Paint and Their Impact on Paint Properties ( Click here)

Different types and grades of paint provide different application and resistance properties, depending upon the kinds and levels of ingredients used to create the paint. In turn, the properties of a paint determine the general quality of the coating. Some of the many paint properties affected by the ingredients are highlighted in this report.

How Color Is Affected by the Ingredients of Paint ( Click here)
Color is integral, and indispensable, to architecture and design. It follows that the architect can benefit from an understanding of how color is achieved with paint, and how paint ingredients can affect color — both initially and over time.

Considerations About Paint for Metal Surfaces ( Click here)
Due to the vulnerability of unprotected metal surfaces to the corrosive effects of moisture and the atmosphere, architects must take different considerations into account when specifying paints for these substrates, compared to substrates such as wood and masonry. This module focuses on those considerations, ranging from the choice of primers and paints to the importance of the topcoat.

2006 AIA Honor Awards Recognize Excellence in Architecture, Interiors, and Urban Design


“There was a wide variety of projects selected from the over 400 entries the jury reviewed for 2006. The jury was interested in projects that fit their context whether it was a chapel, an office building, a campus infill or urban intervention,” said Jury Chair Robert E. Hull, FAIA, from The Miller/Hull Partnership in Seattle. “The diverse background of the jury insured that our selections appealed to a wide range of architectural design. In our deliberations and site visits there was the realization of the special qualities, vitality, and importance that great architecture brings to our society. The projects selected for the 2006 honor awards are a celebration of our profession’s continued vitality.”

Ballard Library and Neighborhood Service Center, Seattle, by Bohlin Cywinski Jackson, for the Seattle Public Library The first major building designed and built within its neighborhood’s new municipal center master plan, this project’s library and service center share a gently sloping site adjacent to a city park currently under construction. The structure draws on the community’s Scandinavian and maritime roots, all the while anticipating its projected demographics of a younger, more diverse population.

Bigelow Chapel, New Brighton, Minn., by Hammel, Green and Abrahamson Inc., for the United Theological Seminary of the Twin Cities
This 5,000-square-foot chapel serves an ecumenical graduate and professional school of theology that houses 250 students of all faiths—from Roman Catholic to Jewish to Unitarian. Rather than thinking of the chapel as a Christian worship space, the architect set forth to embody a “trinity of spiritual qualities” in intimacy, warmth, and light. The space captures intimacy and warmth through use of rippling, honey-colored, translucent, 32-inch-deep maple panels; light streams through the panels and from clerestories and skylights.

Frieder Burda Collection Museum, Baden-Baden, Germany, by Richard Meier & Partners Architects LLP, with associate architect Peter W. Kruse-Freier Architekt, for Sammlung Frieder Burda
This new museum for a private collection harmonizes with its surrounding public park as well as an adjacent Kunsthalle, or art museum. A glass-enclosed bridge connects the new museum to the existing one and shows proper respect to its venerable neighbor by touching its façade as gently as possible.

Children’s Museum of Pittsburgh, Pittsburgh, by Koning Eizenberg Architecture, with Perkins Eastman Architects PC, for Children’s Museum of Pittsburgh
The architects say this museum expansion was inspired by the Chinese proverb that instructs parents to give their children two things: roots and wings. The project expands an existing museum from its home in an 1897 post office into an adjacent planetarium that had long stood vacant.

Joseph A. Steger Student Life Center, University of Cincinnati, by Moore Ruble Yudell Architects & Planners, with associate architect glaserworks, for the University of Cincinnati

This 114,700-square-foot building housing administrative classrooms, computer labs, retail, and food service, as well as a restored 1920s classroom, is a dynamic part of a new spine of campus activity organized along major pedestrian and topographic paths.

Museo Picasso Malaga, Malaga, Spain, by Gluckman Mayner Architects, with associate architect Camara/Martin Delgado Arquitectos, for Fundacion Museo Picasso Malaga
This museum, dedicated to the works of Pablo Picasso, graces the historic city center of Malaga, the artist’s birthplace. The architects fully restored the 16-century Palacio de Buenavista to house the main entry and permanent collection galleries within a project that also included inserting six new buildings into the urban fabric to enclose some 80,000 square feet.

TRUMPF Customer and Administration Building, Ditzingen, Germany, by Barkow Leibinger Architects, for TRUMPF GmbH + Co. KG
Situated between the Autobahn and the existing buildings of a high-tech machine-tool company, this new building for 300 employees creates a new entry courtyard for visitors and customers. The architects worked with three crystalline-formed volumes at the base of the building—lobby, auditorium, and exhibition spaces—and built up at split-level increments to the sixth floor.

Visiting Artists House, Geyserville, Calif., by Jim Jennings Architecture, for Stephen H. Oliver
This 1,700-square-foot residence of two suites accessible to studios serves artists commissioned to work onsite at a former northern California sheep ranch. The architects defined the structure with two 200-foot-long poured-in-place concrete walls that “slice along the crest of a hill, retaining the earth along the length of the cut and carving out prescribed areas for indoor and outdoor living.” The sleeping areas offer private views of the landscaping, which includes a small lake that also feeds water of constant temperature to the building’s mechanical systems.

Washington Convention Center, Washington, D.C., by TVS – D&P Mariani PLLC; with associate architects Thompson Ventulett Stainback PC, Devrouax & Purnell Architects Planners PC, and Mariani Architects Engineers PC; for the Washington Convention Center Authority
The design team faced the challenge of creating the largest enclosed gathering space in the nation’s capital: 2.3 million square feet on a 600,000-square-foot footprint that stretched across six vacant lots. The result is the first vertically stacked, long-span convention center in the country. Given the relatively small footprint and the city’s strict height limits, the architects devised a spatial “sandwich” that buried one of the exhibit halls underground and elevated the other, so that lobbies, meeting rooms, and registration spaces could be at ground level.

Washington State Legislative Building Rehabilitation, Olympia, Wash., by SRG Partnership Inc., with associate architect Einhorn Yaffee Prescott, for Washington State General Administration
The challenge with the 1920s, 300,000-gross-square-foot, four-story brick-and-stone structure that was on the verge of collapse was to extend its life expectancy for another 50 years. The team succeeded in installing all new heating, cooling, plumbing, and fire-protection systems while keeping the historic features of the building intact. Additionally, the capitol dome—via its 16 columns—was reinforced to withstand a severe earthquake.

William J. Clinton Presidential Center, Little Rock, Ark. by Polshek Partnership Architects; with associate architects Polk Stanley Rowland Curzon Porter Architects Ltd, Witsell Evans Rasco Architects and Planners, and Woods Caradine Architects; for the William J. Clinton Foundation
While the principal design goals—to create an inviting, memorable, and inspiring place, and a visually and intellectually accessible destination—seem in the mainstream for a presidential library, this project represents a radical departure from its predecessors in that its site selection intended to rehabilitate a derelict area of abandoned warehouses.

Modern architecture

Modern architecture


Modern architecture is characterized by simplification of form and creation of ornament from the structure and theme of the building. The first variants were conceived early in the 20th century. Modern architecture was adopted by many influential architects and architectural educators, gained popularity after the Second World War, and continues as a dominant architectural style for institutional and corporate buildings in the 21st century. Examples of Modern architecture in the 21st Century include One World Trade Center (2013) in New York City and Tour First (2011), the tallest office building in the Paris metropolitan area. Emporis named Chicago's Modern Aqua Tower (2009) its skyscraper of the year.[1]

[edit] History

[edit] Origins

The Seagram Building, New York City, 1958. One of the finest examples of the functionalist aesthetic and a masterpiece of corporate modernism.

Some historians see the evolution of Modern architecture as a social matter, closely tied to the project of Modernity and thus the Enlightenment. The Modern style developed, in their opinion, as a result of social and political revolutions.[2]

Others see Modern architecture as primarily driven by technological and engineering developments, and it is true that the availability of new building materials such as iron, steel, and glass drove the invention of new building techniques as part of the Industrial Revolution. In 1796, Shrewsbury mill owner Charles Bage first used his 'fireproof' design, which relied on cast iron and brick with flag stone floors. Such construction greatly strengthened the structure of mills, which enabled them to accommodate much bigger machines. Due to poor knowledge of iron's properties as a construction material, a number of early mills collapsed. It was not until the early 1830s that Eaton Hodgkinson introduced the section beam, leading to widespread use of iron construction, this kind of austere industrial architecture utterly transformed the landscape of northern Britain, leading to the description of places like Manchester and parts of West Yorkshire as "Dark satanic mills".

The Crystal Palace by Joseph Paxton at the Great Exhibition of 1851 was an early example of iron and glass construction; possibly the best example is the development of the tall steel skyscraper in Chicago around 1890 by William Le Baron Jenney and Louis Sullivan. Early structures to employ concrete as the chief means of architectural expression (rather than for purely utilitarian structure) include Frank Lloyd Wright's Unity Temple, built in 1906 near Chicago, and Rudolf Steiner's Second Goetheanum, built from 1926 near Basel, Switzerland.

Other historians regard Modernism as a matter of taste, a reaction against eclecticism and the lavish stylistic excesses of Victorian Era and Edwardian Art Nouveau. Note that the Russian word for Art Nouveau, "Модерн", and the Spanish word for Art Nouveau, "Modernismo" are cognates of the English word "Modern" though they carry different meanings.

Whatever the cause, around 1900 a number of architects around the world began developing new architectural solutions to integrate traditional precedents (Gothic, for instance) with new technological possibilities. The work of Louis Sullivan and Frank Lloyd Wright in Chicago, Victor Horta in Brussels, Antoni Gaudi in Barcelona, Otto Wagner in Vienna and Charles Rennie Mackintosh in Glasgow, among many others, can be seen as a common struggle between old and new. An early use of the term in print around this time, approaching its later meaning, was in the title of a book by Otto Wagner.[3][4]

A key organization that spans the ideals of the Arts and Crafts and Modernism as it developed in the 1920s was the Deutscher Werkbund (German Work Federation) a German association of architects, designers and industrialists. It was founded in 1907 in Munich at the instigation of Hermann Muthesius. Muthesius was the author of a three-volume "The English House" of 1905, a survey of the practical lessons of the English Arts and Crafts movement and a leading political and cultural commentator.[5] The purpose of the Werkbund was to sponsor the attempt to integrate traditional crafts with the techniques of industrial mass production. The organization originally included twelve architects and twelve business firms, but quickly expanded. The architects include Peter Behrens, Theodor Fischer (who served as its first president), Josef Hoffmann and Richard Riemerschmid. Joseph August Lux, an Austrian-born critic, helped formulate its agenda.[6]

[edit] Modernism as dominant style

By the 1920s the most important figures in Modern architecture had established their reputations. The big three are commonly recognized as Le Corbusier in France, and Ludwig Mies van der Rohe and Walter Gropius in Germany. Mies van der Rohe and Gropius were both directors of the Bauhaus, one of a number of European schools and associations concerned with reconciling craft tradition and industrial technology.

Frank Lloyd Wright's career, in which he built more than Mies, Le Corbusier and Gropius combined, parallels and influences the work of the European modernists, particularly via the Wasmuth Portfolio, but he refused to be categorized with them claiming that "they" copied his ideas. Wright was a major influence on both Gropius (founder of the Bauhaus) and van der Rohe, however, as well as on the whole of organic architecture. Gropius claimed that his "bible" for forming the Bauhaus was 100 Frank Lloyd Wright drawings that the architect shared with Germany over a decade prior to this point. Many architects in Germany believed that Wright's life would be wasted in the United States, since the US wasn't ready for his architecture. Just as many European architects saw Wright's Larkin Building (1904) in Buffalo, Unity Temple (1905) in Oak Park, and the Robie House (1910) in Chicago as some of the first examples of modern architecture in the 20th century. It would be 2–3 decades later before the European architects would bring their version back to the United States.

In 1932 came the important MOMA exhibition, the International Exhibition of Modern Architecture, curated by Philip Johnson. Johnson and collaborator Henry-Russell Hitchcock drew together many distinct threads and trends, identified them as stylistically similar and having a common purpose, and consolidated them into the International style.

This was an important turning point. With World War II the important figures of the Bauhaus fled to the United States, to Chicago, to the Harvard Graduate School of Design, and to Black Mountain College. While Modern architectural design never became a dominant style in single-dwelling residential buildings, in institutional and commercial architecture Modernism became the pre-eminent, and in the schools (for leaders of the profession) the only acceptable, design solution from about 1932 to about 1984.

Architects who worked in the International style wanted to break with architectural tradition and design simple, unornamented buildings. The most commonly used materials are glass for the facade, steel for exterior support, and concrete for the floors and interior supports; floor plans were functional and logical. The style became most evident in the design of skyscrapers. Perhaps its most famous manifestations include the United Nations headquarters (Le Corbusier, Oscar Niemeyer, Sir Howard Robertson), the Seagram Building and the Toronto-Dominion Centre (Ludwig Mies van der Rohe), and Lever House (Skidmore, Owings, and Merrill). A prominent residential example is the Lovell House (Richard Neutra) in Los Angeles.

Oscar Niemeyer's Casino da Madeira, Funchal, Portugal.

Le Corbusier once described buildings as "machines for living", but people are not machines and it was suggested that they do not want to live in machines. Even Philip Johnson admitted he was "bored with the box." Since the early 1980s many architects have deliberately sought to move away from rectilinear designs, towards more eclectic styles. During the middle of the century, some architects began experimenting in organic forms that they felt were more human and accessible. Mid-century modernism, or organic modernism, was very popular, due to its democratic and playful nature. Oscar Niemeyer, Alvar Aalto and Eero Saarinen were three of the most prolific architects and designers in this movement, which has influenced contemporary modernism.

Modern architecture met with some criticism which began in the 1960s on the grounds that it seemed universal, elitist, and lacked meaning. Siegfried Giedion in the 1961 introduction to his evolving text, Space, Time and Architecture (first written in 1941), could begin "At the moment a certain confusion exists in contemporary architecture, as in painting; a kind of pause, even a kind of exhaustion." At the Metropolitan Museum of Art, a 1961 symposium discussed the question "Modern Architecture: Death or Metamorphosis?" In New York, the coup d'état appeared to materialize in controversy around the Pan Am Building that loomed over Grand Central Station, taking advantage of the modernist real estate concept of "air rights",[7] In criticism by Ada Louise Huxtable and Douglass Haskell it was seen to "sever" the Park Avenue streetscape and "tarnish" the reputations of its consortium of architects: Walter Gropius, Pietro Belluschi and the builders Emery Roth & Sons.

Architects explored Postmodern architecture which offered a blend of some pre-modern elements. By the 1980s, postmodern architecture appeared to trend over modernism; however, postmodern aesthetics lacked traction and by the mid-1990s, a new surge of modern architecture once again established international pre-eminence. As part of this revival, much of the criticism of the modernists was re-evaluated; and a modernistic style once again dominates in institutional and commercial contemporary practice. Although modern and postmodern design compete with a revival of traditional architectural design in commercial and institutional architecture; residential design continues to be dominated by a traditional aesthetic.

The Bailey House, Case Study House #21.

That is not to say that the residential sector in the United States is devoid of examples from the Modernist movement. The Case Study Houses are prime examples of this. Commissioned around the mid-twentieth century, the six homes that were built have had more than 350,000 visitors since their completion, and have influenced many architects over the years. These and other Modern residences tend to focus on humanizing the otherwise harsh ideal, making them more livable and ultimately more appealing to real people. Many of these designs use a similar tactic: blurring the line between indoor and outdoor spaces. This is achieved by embracing "the box" while at the same time dissolving it into the background with minimal structure and large glass walls.[8] Some critics claim that these spaces remain too cold and static for the average person to function, however. The materials utilized in a large number of Modern homes are not hidden behind a softening facade. While this may make them somewhat less desirable for the general public, most modernist architects see this as a necessary and pivotal tenet of Modernism: uncluttered and purely Minimal design.

[edit] Characteristics

Modern architecture is usually characterized by:

  • an adoption of the principle that the materials and functional requirements determine the result
  • an adoption of the machine aesthetic
  • an emphasis of horizontal and vertical lines
  • a creation of ornament using the structure and theme of the building, or a rejection of ornamentation.
  • a simplification of form and elimination of "unnecessary detail"
  • an adoption of expressed structure
  • Form follows function

[edit] Preservation

Private organizations such as Docomomo International, the World Monuments Fund, and the Recent Past Preservation Network are working to safeguard and document imperiled Modern architecture. In 2006, the World Monuments Fund launched Modernism at Risk, an advocacy and conservation program.

Following the destruction caused by Hurricane Katrina, Modern structures in New Orleans have been increasingly slated for demolition. Currently plans are underway to demolish many of the city's Modern public schools, as well as large portions of the city's Civic Plaza. FEMA funds will contribute to razing the State Office Building and State Supreme Court Building, both designed by the collaborating architectural firms of August Perez and Associates; Goldstein, Parham and Labouisse; and Favrot, Reed, Mathes and Bergman. The New Orleans Recovery School District has proposed demolitions of schools designed by Charles R. Colbert, Curtis and Davis, and Ricciuti Associates. The 1959 Lawrence and Saunders building for the New Orleans International Longshoremen's Association Local 1419 is currently threatened with demolition although the union supports its conservation.

Chinese architecture

Chinese architecture

Chinese architecture refers to a style of architecture that has taken shape in Asia over many centuries. The structural principles of Chinese architecture have remained largely unchanged, the main changes being only the decorative details. Since the Tang Dynasty, Chinese architecture has had a major influence on the architectural styles of Korea, Vietnam, Japan and Taiwan.

The architecture of China is as old as Chinese civilization. From every source of information - literary, graphic, exemplary - there is strong evidence testifying to the fact that the Chinese have always employed an indigenous system of construction that has retained its principal characteristics from prehistoric times to the present day. Over the vast area from Chinese Turkistan to Japan, from Manchuria to the northern half of French Indochina, the same system of construction is prevalent; and this was the area of Chinese cultural influence. That this system of construction could perpetuate itself for more than four thousand years over such a vast territory and still remain a living architecture, retaining its principal characteristics in spite of repeated foreign invasions - military, intellectual, and spiritual - is a phenomenon comparable only to the continuity of the civilization of which it is an integral part.
Liang, Ssu-ch'eng, 1984[1]

The following article gives a cursory explanation of traditional Chinese architecture, before the introduction of Western building methods during the early 20th century. Throughout the 20th Century, however, Western-trained Chinese architects have attempted to combine traditional Chinese designs into modern architecture (usually government), with only limited success. Moreover, the pressure for urban development throughout contemporary China required higher speed of construction and higher floor area ratio, which means that in the great cities the demand for traditional Chinese buildings, which are normally less than 3 levels, has declined in favor of modern architecture. However, the traditional skills of Chinese architecture, including major and minor carpentry, masonry, and stone masonry, are still applied to the construction of vernacular architecture in the vast rural area in China.

[edit] Features

[edit] Architectural Bilateral symmetry

An important feature in Chinese architecture is its emphasis on articulation and bilateral symmetry, which signifies balance. Bilateral symmetry and the articulation of buildings are found everywhere in Chinese architecture, from palace complexes to humble farmhouses. When possible, plans for renovation and extension of a house will often try to maintain this symmetry provided that there is enough capital to do so.[2] Secondary elements are positioned either side of main structures as two wings to maintain overall bilateral symmetry.

In contrast to the buildings, Chinese gardens are a notable exception which tends to be asymmetrical. The principle underlying the garden's composition is to create enduring flow.

[edit] Enclosure

Contemporary Western architectural practices typically involve surrounding a building by an open yard on the property. This contrasts with much of traditional Chinese architecture, which involves constructing buildings or building complexes that take up an entire property but encloses open spaces within itself. These enclosed spaces come in two forms: the open courtyard (院) and the "sky well" (天井)[2].

The use of open courtyards is a common feature in many types of Chinese architectures. This is best exemplified in the Siheyuan, which consists of an empty space surrounded by buildings connected with one another either directly or through verandas.

Although large open courtyards are less commonly found in southern Chinese architecture, the concept of a "open space" surrounded by buildings, which is seen in northern courtyard complexes, can be seen in the southern building structure known as the "sky well". This structure is essentially a relatively enclosed courtyard formed from the intersections of closely spaced buildings and offer small opening to the sky through the roof space from the floor up.

These enclosures serve in temperature regulation and in venting the building complexes. Northern courtyards are typically open and facing the south to allow the maximum exposure of the building windows and walls to the sun while keeping the cold northern winds out. Southern sky wells are relatively small and serves to collect rain water from the roof tops while restricting the amount of sunlight that enters the building. Sky wells also serve as vents for rising hot air, which draws cool air from the lowers stories of the house and allows for exchange of cool air with the outside.

[edit] Hierarchical

The projected hierarchy and importance and uses of buildings in traditional Chinese architecture are based on the strict placement of buildings in a property/complex. Buildings with doors facing the front of the property are considered more important than those facing the sides. Building facing away from the front of the property are the least important.

As well, building in the rear and more private parts of the property are held in higher esteem and reserve for elder members of the family or ancestral plaques than buildings near the front, which are typically for servants and hired help. Front facing buildings in the back of properties are used particularly for rooms of celebratory rites and for the placement of ancestral halls and plaques. In multiple courtyard complexes, Central courtyard and their buildings are considered more important than peripheral ones, the latter which are typically used as storage or servant's rooms or kitchens[2].

[edit] Horizontal emphasis

Classical Chinese buildings, especially those of the wealthy are built with an emphasis on breadth and less on height, with close heavy platform and a large roof that floats over this base, with the vertical walls not well emphasized. This contrasts Western architecture, which tends to grow in height and depth. Chinese architecture stresses the visual impact of the width of the buildings.

The halls and palaces in the Forbidden City, for example, have rather low ceilings when compared to equivalent stately buildings in the West, but their external appearances suggest the all-embracing nature of imperial China. These ideas have found their way into modern Western architecture, for example through the work of Jørn Utzon.[5] This of course does not apply to pagodas, which are and limited to religious building complexes.

[edit] Cosmological concepts

Chinese architecture from early times used concepts from Chinese cosmology such as feng shui (geomancy) and daoism to organize construction and layout from common residences to imperial and religious structures[2]. This includes the use of:

  • Screen walls to face the main entrance of the house, which stems from the belief that evil things travel on straight lines.
  • Talismans and imagery of good fortune:
    • Door gods displayed on doorways to ward evil and encourage the flow of good fortune
    • Three anthropomorphic figures representing Fu Lu Shou (福祿壽 fú-lù-shòu) stars are prominently displayed, sometimes with the proclamation "the threes star are present" (三星在 sān-xīng-zài)
    • Animals and fruits that symbolize good fortune and prosperity, such as bats and pomegranates, respectively. The association is often done through rebuses.
  • Orienting the structure with its back to elevated landscape and ensuring that there is water in the front. Considerations are also made such that the generally windowless back of the structure faces the north, where the wind is coldest in the winter
  • Ponds, pools, wells, and other water sources are usually built into the structure

The use of certain colors, numbers and the cardinal directions in traditional Chinese architecture reflected the belief in a type of immanence, where the nature of a thing could be wholly contained in its own form. Although the Western tradition gradually developed a body of architectural literature, little was written on the subject in China, and the earliest text, the Kaogongji, was never disputed. However, ideas about cosmic harmony and the order of the city were usually interpreted at their most basic level, so a reproduction of the "ideal" city never existed. Beijing as reconstructed throughout the 15th and 16th century remains one of the best examples of traditional Chinese town planning.

[edit] Construction

[edit] Structure

Tenon and mortice work of tie beams and cross beams, from Li Jie's building manual Yingzao Fashi, printed in 1103.
  • Use of large structural timbers for primary support of the roof of a building. Wooden timber, usually large trimmed logs, are used as load-bearing columns and lateral beams for framing buildings and supporting the roofs. These structural timbers are prominently displayed in finished structures. However, it is not known how the ancient builders raised the huge wooden load bearing columns into position.

Although, structural walls are also commonly found in Chinese architecture, most timber framed architecture are preferred when economically feasible.

  • Timber frames are typically constructed with jointnary and doweling alone, seldom with the use of glue or nails. Structural stability is further ensured through the use of heavy beams and roofs, which weighs the structure down.
  • Using even numbers of columns in a building structure to produce odd numbers of bays (間). With the inclusion of a main door to a building in the centre bay, symmetry is maintained
  • The common use of curtain walls or door panels to delineate rooms or enclose a building, with the general deemphasis of load-bearing walls in most higher class construction
  • Flat roofs are uncommon while gabled roofs are almost omnipresent in traditional Chinese architecture. Three main types of roofs are found
    1. Straight inclined: Roofs with a single incline. These are the most economical type of roofing and are most prevalent in commoner architectures
    2. Multi-inclined: Roofs with 2 or more sections of incline. These roofs are used in higher class constructions, from the dwellings of wealthy commoners to palaces
    3. Sweeping: Roofs with a sweeping curvature that rises at the corners of the roof. The types of roof construction are usually reserved for temples and palaces although it may also be found in the homes of the wealthy. In the former cases, the ridges of the roof are usually highly decorated with ceramic figurines.
  • The roof apex of a large hall is usually topped with a ridge of tiles for both decorative purposes but also to weight down the layers of roofing tiles for stability. These ridges are often well decorated, especially for religious or palatial structures. In some regions of China, the ridges are sometimes extended or incorporated from the walls of the building to form matouqiang (horse-head walls), which serve as a fire deterrent from drifting embers.

[edit] Materials and history

Models of watchtowers and other buildings made during the Eastern Han Dynasty (AD 25–220); while these models were made of ceramics, the real versions were made of easily perishable wood and have not survived.

Unlike other building construction materials, old wooden structures often do not survive because they are more vulnerable to weathering and fires and are naturally subjected to rotting over time. Although now nonexistent wooden residential towers, watchtowers, and pagodas predated it by centuries, the Songyue Pagoda built in 523 is the oldest extant pagoda in China; its use of brick instead of wood had much to do with its endurance throughout the centuries. From the Tang Dynasty (618–907) onwards, brick and stone architecture gradually became more common and replaced wooden edifices. The earliest of this transition can be seen in building projects such as the Zhaozhou Bridge completed in 605 or the Xumi Pagoda built in 636, yet stone and brick architecture is known to have been used in subterranean tomb architecture of earlier dynasties.

In the early 20th century, there were no known fully wood-constructed Tang Dynasty buildings that still existed; the oldest so far discovered was the 1931 find of Guanyin Pavilion at Dule Monastery, dated 984 during the Song.[6] This was until the architectural historians Liang Sicheng (1901–1972), Lin Huiyin (1904–1955), Mo Zongjiang (1916–1999), and Ji Yutang (1902–c. 1960s) discovered that the Great East Hall of Foguang Temple on Mount Wutai in Shanxi was reliably dated to the year 857 in June 1937.[6] The groundfloor dimensions for this monastic hall measures 34 by 17.66 m (111 ft by 57 ft).[7] A year after the discovery at Foguang, the main hall of nearby Nanchan Temple on Mount Wutai was reliably dated to the year 782,[8] while a total of six Tang era wooden buildings have been found by the 21st century.[9] The oldest existent multistory wooden pagoda that has survived intact is the Pagoda of Fogong Temple of the Liao Dynasty, located in Ying County of Shanxi. While the East Hall of Foguang Temple features only seven types of bracket arms in its construction, the 11th century Pagoda of Fogong Temple features a total of fifty-four.[10]

The earliest walls and platforms in China were of rammed earth construction, and over time, brick and stone became more frequently used. This can be seen in ancient sections of the Great Wall of China, while the brick and stone Great Wall seen today is a renovation of the Ming Dynasty (1368–1644).

Chinese classifications for architecture include:

[edit] Architectural types

[edit] Commoner

As for the commoners, be they bureaucrats, merchants or farmers, their houses tended to follow a set pattern: the center of the building would be a shrine for the deities and the ancestors, which would also be used during festivities. On its two sides were bedrooms for the elders; the two wings of the building (known as "guardian dragons" by the Chinese) were for the junior members of the family, as well as the living room, the dining room, and the kitchen, although sometimes the living room could be very close to the center.

Sometimes the extended families became so large that one or even two extra pairs of "wings" had to be built. This resulted in a U-shaped building, with a courtyard suitable for farm work; merchants and bureaucrats, however, preferred to close off the front with an imposing front gate. All buildings were legally regulated, and the law held that the number of storeys, the length of the building and the colours used depended on the owner's class. Some commoners living in areas plagued by bandits built communal fortresses called Tulou for protection.

[edit] Imperial

There were certain architectural features that were reserved solely for buildings built for the Emperor of China. One example is the use of yellow roof tiles; yellow having been the Imperial color, yellow roof tiles still adorn most of the buildings within the Forbidden City. The Temple of Heaven, however, uses blue roof tiles to symbolize the sky. The roofs are almost invariably supported by brackets ("dougong"), a feature shared only with the largest of religious buildings. The wooden columns of the buildings, as well as the surface of the walls, tend to be red in color. Black is also a famous color often used in pagodas. They believe the gods are inspired by the black color to descend on to the earth.

The Chinese five-clawed dragon, adopted by the first Ming emperor for his personal use, was used as decoration on the beams, pillars, and on the doors on Imperial architecture. Curiously, the dragon was never used on roofs of imperial buildings.

Only the buildings used by the imperial family were allowed to have nine jian (間, space between two columns); only the gates used by the Emperor could have five arches, with the centre one, of course, being reserved for the Emperor himself. The ancient Chinese favored the color red. The buildings faced south because the north had a cold wind.

Beijing became the capital of China after the Mongol invasion of the 13th century, completing the easterly migration of the Chinese capital begun since the Jin dynasty, the Ming uprising in 1368 reasserted Chinese authority and fixed Beijing as the seat of imperial power for the next five centuries. The Emperor and the Empress lived in palaces on the central axis of the Forbidden City, the Crown Prince at the eastern side, and the concubines at the back (therefore the numerous imperial concubines were often referred to as "The Back Palace Three Thousand"). However, during the mid-Qing Dynasty, the Emperor's residence was moved to the western side of the complex. It is misleading to speak of an axis in the Western sense of a visual perspective ordering facades, rather the Chinese axis is a line of privilege, usually built upon, regulating access - there are no vistas, but a series of gates and pavilions.

Numerology heavily influenced Imperial Architecture, hence the use of nine in much of construction (nine being the greatest single digit number) and reason why The Forbidden City in Beijing is said to have 9,999.9 rooms - just short of the mythical 10,000 rooms in heaven. The importance of the East (the direction of the rising sun) in orienting and siting Imperial buildings is a form of solar worship found in many ancient cultures, where the notion of Ruler is affiliated with the Sun.

The tombs and mausoleums of imperial family members, such as the 8th century Tang Dynasty tombs at the Qianling Mausoleum, can also be counted as part of the imperial tradition in architecture. These above-ground earthen mounds and pyramids had subterranean shaft-and-vault structures that were lined with brick walls since at least the Warring States (481–221 BCE).[11]

[edit] Religious

Generally speaking, Buddhist architecture follow the imperial style. A large Buddhist monastery normally has a front hall, housing the statue of a Bodhisattva, followed by a great hall, housing the statues of the Buddhas. Accommodations for the monks and the nuns are located at the two sides. Some of the greatest examples of this come from the 18th century temples of the Puning Temple and the Putuo Zongcheng Temple. Buddhist monasteries sometimes also have pagodas, which may house the relics of the Gautama Buddha; older pagodas tend to be four-sided, while later pagodas usually have eight-sides.

Daoist architecture, on the other hand, usually follow the commoners' style. The main entrance is, however, usually at the side, out of superstition about demons which might try to enter the premise. (See feng shui.) In contrast to the Buddhists, in a Daoist temple the main deity is located at the main hall at the front, the lesser deities at the back hall and at the sides.

The tallest pre-modern building in China was built for both religious and martial purposes. The Liaodi Pagoda of 1055 AD stands at a height of 84 m (275 ft), and although it served as the crowning pagoda of the Kaiyuan monastery in old Dingzhou, Hebei, it was also used as a military watchtower for Song Dynasty soldiers to observe potential Liao Dynasty enemy movements.

The architecture of the mosques and gongbei tomb shrines of China's Muslims often combines traditional Chinese styles with Middle Eastern influences.

[edit] Urban planning

Chinese urban planning is based on fengshui geomancy and the field-well system of land division both used since the Neolithic age. The basic field-well diagram is overlaid with the luoshu, a magic square divided into 9 sub-squares, and linked with Chinese numerology.[13]

[edit] Miniature models

Although mostly only ruins of brick and rammed earth walls and towers from ancient China (i.e. before the 6th century AD) have survived, information on ancient Chinese architecture (especially wooden architecture) can be discerned from more or less realistic clay models of buildings created by the ancient Chinese as funerary items. This is similar to the paper joss houses burned in some modern Chinese funerals. The following models were made during the Han Dynasty (202 BCE–AD 220):

A pottery palace from the Han Dynasty (202 BC –AD 220)
Two residential towers joined by a bridge, pottery miniature, Han Dynasty (202 BC–AD 220)

A pottery model of a well from the Han Dynasty (202 BC–AD 220)
A pottery tower from the Han Dynasty (202 BC–AD 220)

During the Jin Dynasty (265–420) and the Six Dynasties, miniature models of buildings or entire architectural ensembles were often made to decorate the tops of the so-called "soul vases" (hunping), found in many tombs of that period.[14]
