GATE Architecture & Planning Architecture Syllabus

How does the pointed arch differ structurally from the semicircular (Roman) arch?

The pointed arch directs thrust more steeply downward (more vertically), reducing outward lateral thrust, and allows arches of differing spans to reach the same height, giving design flexibility for vaulting rectangular bays.

What is a flying buttress and what does it do?

A flying buttress is an external arched support that transfers the lateral (outward) thrust of the vault across an open space to a freestanding pier buttress, allowing the walls to be opened up with large windows.

Name characteristic decorative/window features of Gothic cathedrals.

Rose windows, tracery, stained glass, pointed (lancet) windows, ribbed vaults, pinnacles, gargoyles, and tall spires. Examples: Notre-Dame de Paris, Chartres, Reims, Amiens.

What marked the beginning of Renaissance architecture and who is considered its pioneer?

A revival of classical Roman principles (symmetry, proportion, orders, geometry) beginning in 15th-century Florence. Filippo Brunelleschi is the pioneer, famous for the dome of Florence Cathedral (Santa Maria del Fiore).

How did Brunelleschi's dome of Florence Cathedral solve its structural problem?

It used a double-shell (inner and outer) octagonal dome built without conventional centering, employing a herringbone brick pattern and stone/iron tension chains (rings) to contain hoop stresses across its roughly 42 m span.

Name two influential Renaissance architects besides Brunelleschi and a key contribution of each.

Leon Battista Alberti (theorist; treatise 'De re aedificatoria'; façade of Santa Maria Novella) and Donato Bramante (High Renaissance; original plan for St. Peter's, the Tempietto). Andrea Palladio is also key (villas, 'I Quattro Libri', Palladianism).

What is Palladianism and which treatise codified it?

Palladianism is a style based on the symmetry, classical orders and harmonic proportions of Andrea Palladio, codified in his treatise 'I Quattro Libri dell'Architettura' (The Four Books of Architecture), influential on Villa Rotonda and later European/American architecture.

Compare Renaissance and Baroque architecture in terms of form and emotional intent.

Renaissance is calm, static, balanced, and rational with clear classical proportion. Baroque is dynamic, dramatic and theatrical—using curves, movement, strong light-shadow contrast, richly modelled façades and grandeur to evoke emotion and awe.

Name characteristic features of Baroque architecture and one major architect.

Undulating/curved façades, oval plans, dramatic light, dynamic spatial movement, grandeur and ornamentation. Major architects: Gian Lorenzo Bernini (St. Peter's colonnade) and Francesco Borromini (San Carlo alle Quattro Fontane).

How does Rococo differ from Baroque?

Rococo is a later (18th-century), lighter, more delicate and playful evolution of Baroque. It favours pastel colours, asymmetry, intricate ornament (shells, scrolls, foliage—'rocaille'), and intimate interiors rather than monumental grandeur.

What is Art Nouveau and what is its defining visual character?

A late-19th/early-20th-century style (c. 1890–1910) characterized by flowing, organic, curvilinear forms inspired by nature—whiplash curves, plant and floral motifs, and integration of art with architecture. Key figures: Victor Horta, Hector Guimard, Antoni Gaudí.

What is Art Deco and how does it visually contrast with Art Nouveau?

Art Deco (1920s–30s) uses bold geometric forms, streamlined shapes, zigzags, chevrons, stepped (ziggurat) massing, and rich/luxurious materials. Unlike the organic curves of Art Nouveau, it is geometric, symmetrical and machine-age in spirit. Example: Chrysler Building, New York.

Define Eclecticism in architecture.

Eclecticism is a 19th-century approach that combines elements, motifs and styles borrowed from various historical periods and sources within a single building or design, rather than adhering to one stylistic tradition.

What is the International Style and what are its defining characteristics?

A modernist style emerging in the 1920s–30s emphasizing volume over mass, regularity over symmetry, absence of applied ornament, flat roofs, smooth machine-finished surfaces, glass curtain walls and an honest expression of structure. Associated with Gropius, Mies van der Rohe and Le Corbusier.

State Le Corbusier's 'Five Points of a New Architecture'.

(1) Pilotis (supporting columns lifting the building), (2) free plan, (3) free façade, (4) horizontal ribbon windows (fenêtre en longueur), and (5) roof garden. Exemplified by Villa Savoye.

Which famous modernist phrases are associated with Mies van der Rohe and Louis Sullivan?

Mies van der Rohe: 'Less is more' and 'God is in the details.' Louis Sullivan: 'Form follows function.'

What was the Bauhaus and why is it significant to modern architecture?

The Bauhaus (founded 1919 by Walter Gropius in Weimar, Germany) was a design school that unified art, craft and technology, promoting functional, minimal, geometric design suited to mass production. It strongly shaped the International Style and modern design education.

Define Post-Modernism in architecture and contrast it with Modernism.

Post-Modernism (from c. 1960s–70s) reintroduced ornament, historical reference, symbolism, colour, wit and contextual variety—reacting against the austere, uniform functionalism of Modernism. Robert Venturi countered 'less is more' with 'less is a bore.'

What did Robert Venturi mean by 'Decorated Shed' versus 'Duck'?

In 'Learning from Las Vegas,' a 'Duck' is a building whose overall form itself is the symbol/sign (sculptural expression), while a 'Decorated Shed' is a conventional functional structure to which signs and ornament are applied. Venturi favoured the decorated shed.

Define Deconstructivism in architecture and name two associated architects.

A movement (from the late 1980s) characterized by fragmentation, non-rectilinear shapes, distorted geometry, and the apparent absence of harmony, continuity or symmetry—giving controlled chaos. Architects: Frank Gehry, Zaha Hadid, Daniel Libeskind, Peter Eisenman, Rem Koolhaas, Coop Himmelb(l)au.

Which 1988 event and exhibition formally introduced Deconstructivist architecture?

The 'Deconstructivist Architecture' exhibition at the Museum of Modern Art (MoMA), New York, in 1988, curated by Philip Johnson and Mark Wigley.

How did modern art movements like Cubism and De Stijl influence architecture?

Cubism's fragmentation of form and multiple viewpoints and De Stijl's abstraction into pure geometry, primary colours and orthogonal planes (e.g., Rietveld's Schröder House) directly inspired modernist spatial composition, planar walls and asymmetric balance.

What is the De Stijl movement and a built architectural example?

De Stijl (Neoplasticism, c. 1917, Netherlands) reduced design to horizontal/vertical lines, rectangular planes, and primary colours (red, blue, yellow) plus black, white and grey. Architectural example: Gerrit Rietveld's Schröder House (1924).

Define 'vernacular architecture' and give its key characteristics.

Vernacular architecture is built by local people using indigenous materials, traditional techniques and local skills, responding to climate, culture and available resources, usually without formally trained architects. It is climate-responsive, economical and regionally distinctive.

Give examples of Indian vernacular/traditional dwelling types and their regions.

Examples: the courtyard 'haveli' (Rajasthan/North India), the 'nalukettu' (Kerala courtyard house), 'wada' (Maharashtra), 'bhunga' (circular mud huts of Kutch, Gujarat), Toda huts (Nilgiris), and Assam-type bamboo/'ikra' houses—each adapted to local climate and materials.

What climate-responsive features are typical of traditional Indian architecture in hot regions?

Internal courtyards for ventilation and light, thick masonry/mud walls for thermal mass, jaali (perforated screens) for shaded ventilation, jharokhas and chhajjas (overhangs/balconies) for shade, stepwells (baoli) for water and cooling, and small windows to limit heat gain.

What does 'Oriental architecture' broadly refer to and name two of its traditions?

Oriental architecture refers to the architectural traditions of East and South-East Asia. Examples include Chinese architecture (timber post-and-beam, dougong brackets, curved tiled roofs) and Japanese architecture (timber framing, shoji screens, pagodas, modular tatami planning).

What is a 'dougong' in Chinese architecture and a 'pagoda'?

A dougong is an interlocking system of wooden bracket sets between column top and roof beam that supports broad overhanging eaves and distributes load without nails. A pagoda is a tiered, multi-storey tower (of Buddhist origin) with multiple projecting eaves, common across East Asia.

Name some 'recent trends' / movements in contemporary architecture.

Sustainable/green and net-zero architecture, parametric and computational design, Deconstructivism, High-tech architecture, blob/organic architecture, biophilic design, smart/responsive buildings, and adaptive reuse—often using digital fabrication and new materials.

What is High-tech architecture and give one example.

High-tech (Structural Expressionism) celebrates and exposes a building's structure and services (ducts, lifts, trusses) as the architecture itself, using industrial materials like steel and glass. Example: the Centre Pompidou, Paris (Renzo Piano and Richard Rogers).
