Architecture

• 1. Introduction

  ›

  Architecture is the study and practice of designing structures, especially habitable ones. It draws on civil engineering techniques, yet it is counted among the visual arts. A single phrase from a Roman writer in the early 1st century BC still anchors the whole field. Vitruvius held that a good building must embody firmitas, utilitas, and venustas: durability, utility, and beauty. That ancient triad raises a question the rest of this story keeps circling back to. When does a pile of stone, wood, and concrete stop being mere construction and become art? Historical civilizations are often identified by the buildings they left behind. So what did those buildings express, and who decided what counted as beautiful? The answers stretch across all seven continents and across thousands of years.

• 2. The Triad And Its Heirs

  Firmitas, utilitas, venustas: the three words come from De architectura, the earliest surviving text on architectural theory. Vitruvius argued that an architect should fulfill each of the three attributes as well as possible. Durability meant a building should stand robustly and stay in good condition. Utility meant it should suit the purposes it was built for. Beauty meant it should please the eye.

  Leon Battista Alberti carried the idea further in his treatise De re aedificatoria. For Alberti, beauty was chiefly a matter of proportion, with ornament playing a secondary part. He tied those proportions to the idealized human figure and the golden mean. Beauty, in his view, was an inherent part of an object rather than something applied superficially, and it rested on universal, recognizable truths.

  Louis Sullivan, a 19th-century architect of skyscrapers, distilled a different precept. He declared that form follows function. The word function began to replace the classical word utility. Function came to cover not only practical concerns but aesthetic, psychological, and cultural ones too. Late in the 20th century a further concept joined structure and function: sustainability, and with it the idea of sustainable architecture.

• 3. Construction Versus Art

  ›

  Le Corbusier drew the line between building and architecture with unusual directness. He wrote: "You employ stone, wood, and concrete, and with these materials you build houses and palaces: that is construction. Ingenuity is at work. But suddenly you touch my heart, you do me good. I am happy and I say: This is beautiful. That is Architecture." His point was that competent construction and architecture are not the same thing.

  Ludwig Mies van der Rohe, a contemporary of Le Corbusier, located the threshold even lower. In a 1959 interview he is said to have stated that architecture starts when you carefully put two bricks together. There, he said, it begins.

  John Ruskin, the 19th-century English art critic, set a narrower test in his Seven Lamps of Architecture, published in 1849. For Ruskin a building was not truly a work of architecture unless it was in some way adorned. A well-constructed, well-proportioned, functional building still needed string courses or rustication at the very least. The philosophy of architecture, a branch of the philosophy of art, has drawn thinkers from Plato to Michel Foucault, Gilles Deleuze, Robert Venturi, and Ludwig Wittgenstein, all wrestling with whether architecture is distinct from building.

• 4. Books That Taught Europe

  ›

  Sebastiano Serlio, an Italian Mannerist architect, painter, and theorist, wrote a treatise in the 16th century titled Tutte L'Opere D'Architettura et Prospetiva. It was the first handbook to stress the practical rather than the theoretical side of architecture, and the first to catalog the five orders. Its influence spread across Europe.

  Giorgio Vasari, also writing in the 16th century, introduced the notion of style in the arts. His Lives of the Most Excellent Painters, Sculptors, and Architects had been translated into Italian, French, Spanish, and English by the 18th century.

  Augustus Welby Northmore Pugin took a combative stance in the early 19th century. His book Contrasts, published in 1836, set the modern industrial world he disparaged against an idealized neo-medieval one. Pugin believed Gothic architecture was the only true Christian form of architecture. The aesthetics of architecture remain a contested topic, and studies generally find a strong public preference for traditional and classical styles over modernist designs. James Stevens Curl argues that modernist architects often favor designs that are alienating and environmentally damaging.

  Çatalhöyük in modern-day Turkey and Mohenjo-daro in modern-day Pakistan grew rapidly from rural settlements into proto-cities. Neolithic sites also include Göbekli Tepe in Turkey, Jericho in the Levant, Mehrgarh in Pakistan, Skara Brae in Orkney, and Cucuteni-Trypillian settlements in Romania, Moldova, and Ukraine. Building first evolved from the dynamics between needs such as shelter, security, and worship, and means such as available materials and skills.

  In Egypt and Mesopotamia, architecture reflected a constant engagement with the divine, and rulers used monumental scale to represent political power. In Egypt the education of state architects was closely linked to the priestly class, with trade secrets passed from father to son. Plans were drawn and then carried out using the ruler, square, and triangle. Greek and Roman civilizations shifted that focus, evolving their architecture from civic ideals and developing the classical orders.

  Asian traditions ran on their own logic. Hindu temple architecture developed from around the 5th century CE, governed in theory by concepts in the Shastras and concerned with expressing both macrocosm and microcosm. Buddhism was linked to a move toward stone and brick, probably beginning as rock-cut architecture that has often survived well. Early Asian writings include the Kao Gong Ji of China from the 7th to 5th centuries BC, the Shilpa Shastras of ancient India, the Manjusri Vasthu Vidya Sastra of Sri Lanka, and Araniko of Nepal.

• 6. Africa's Many Hands

  ›

  The great Zimbabwe walls stand as durable, long-lasting stone construction on a continent of many climates, cultures, and histories. Traditional African architecture blends building traditions and a wide range of materials including mud, stone, and wood. Fractal scaling appears often, so smaller parts of a structure mirror the overall design, visible in both village layouts and decorative elements.

  Wattle and daub, used across many areas, wraps wooden frames in mud to make rounded structures that help regulate interior temperature. In West Africa, places such as Porto-Novo in Benin, Lagos Island and Zaria in Nigeria, and Dakar in Senegal are dominated by Sudano-Sahelian, Afro-modernist, and Sobrado styles. The Sobrado style is a multi-storied, Portuguese-Brazilian baroque form suited to dry, hot climates, with central or rear courtyards, stuccoed facades, symmetrical layouts, tiled roofs, and prominent balconies.

  Along the Swahili Coast of East Africa, many homes are built from coral stone with mangrove pole roofs, blending local, Arabic, and Islamic styles through trade across the Indian Ocean. Ethiopia carved its churches at Lalibela directly into the ground in the 13th century. Islamic architecture, which began in the 7th century, absorbed forms from the ancient Middle East and Byzantium and later reached the Balkans through the expansion of the Ottoman Empire.

• 7. Cathedrals To Skyscrapers

  ›

  Magister lathomorum, master of the masons, was how contemporary documents sometimes named the medieval architect. In Europe during the Medieval period, craftsmen formed guilds to organize their trades, and written contracts survive, especially for ecclesiastical buildings. The major undertakings were abbeys and cathedrals. From about 900 onward, the movement of clerics and tradesmen carried architectural knowledge across the continent, producing the pan-European Romanesque and Gothic styles.

  From about 1400 onward, Renaissance Europe revived Classical learning alongside Renaissance humanism. Buildings were now ascribed to named individuals: Brunelleschi, Alberti, Michelangelo, Palladio. The cult of the individual had begun, though no firm line yet separated artist, architect, and engineer. At that stage an artist could still design a bridge, since the structural calculations stayed within a generalist's reach.

  That unity later broke apart. As scientific knowledge and new materials advanced, architecture and engineering began to separate, and the architect concentrated on aesthetics and humanist aspects. The gentleman architect served wealthy clients, drawing on historical prototypes, as in the Neo Gothic and Scottish baronial country houses of Great Britain. Formal training, such as at the Ecole des Beaux-Arts in France in the 19th century, prized beautiful drawings over context and feasibility, while the Industrial Revolution made ornament cheap through mass production.

• 8. Modernism And Its Discontents

  ›

  The Deutscher Werkbund, formed in 1907 to produce better quality machine-made objects, helped clear the ground for what came next. The Bauhaus school, founded in Weimar, Germany in 1919, viewed a building as the apex of art, craft, and technology. Immediately after World War I, pioneering modernists pursued a wholly new style for a post-war social and economic order aimed at the middle and working classes. They reduced buildings to pure forms, stripping away historical references and ornament, and exposed steel beams and concrete surfaces rather than hiding them.

  Frank Lloyd Wright developed organic architecture, in which form was defined by environment and purpose, with Robie House and Fallingwater as prime examples. Mies van der Rohe, Philip Johnson, and Marcel Breuer built beauty from the inherent qualities of materials and modern techniques such as steel-frame construction, which gave rise to high-rise superstructures. Fazlur Rahman Khan's development of the tube structure was a breakthrough for building ever higher. By mid-century modernism had become the International Style, epitomized by the Twin Towers of New York's World Trade Center, designed by Minoru Yamasaki.

  A reaction followed. The second generation, including Paul Rudolph, Marcel Breuer, and Eero Saarinen, pushed into Brutalism, with expressive sculptural facades of unfinished concrete. A younger generation then judged modernism and Brutalism too austere and monotone. Robert Venturi defined postmodern architecture as a decorated shed, an ordinary building embellished on the outside, and set it against modernist ducks with their unnecessarily expressive forms. Interest in sustainable design later grew after the 1973 oil embargo, and the U.S. Green Building Council's LEED rating system became influential in pushing architecture schools and developers toward greener building.
