An Art Nouveau façade of sinuous, organic ornament and flowing curves — the 'new art' around 1900 sought a modern style in the forms of nature.
Unit IIIHistory of Architecture - IV

Reform & Art Nouveau

Craft against the machine, the organic line, and 'form follows function' — the turn of the century searches for a modern style.

≈ 40 min + study taskBy Amogh N. P

The engineers had the new materials — but their bare iron sheds struck many as ugly, and the century's endless copying of old styles felt exhausted. Around 1900 a series of movements set out to find a genuinely modern beauty. The Arts and Crafts movement answered the machine with honest hand-craft; Art Nouveau answered it with the sinuous, living line of nature; and in Chicago, Louis Sullivan answered the tall building with a slogan — "form follows function" — and passed it to a young draughtsman, Frank Lloyd Wright, who would reinvent the house.

How the century answered the machine

Four reform ideas

Truth to materials, the organic line, the building as a total work of art, and "form follows function" — four ideas, pulling in different directions, but all trying to escape the twin dead ends of machine shoddiness and historical revival.[1, 3]

Truth to materials: the honest joint Honest — the joint is the ornament pegs do real work, and are left visible Dishonest — ornament glued on fake moulding, doing nothing
DiagramTruth to materials contrasted: an honest pegged timber joint that does real work and is left visible, versus a plain surface with a fake ornamental moulding merely glued on

Arts and Crafts, against the machine

John Ruskin and William Morris hated what industry did to building and to the worker: shoddy machine ornament, dishonest imitation, and craft reduced to drudgery. Their Arts and Crafts movement argued for honest construction — a material shown as what it is, a joint that does real work and is allowed to be seen, and the dignity of the hand-made. Philip Webb's Red House (1859) for Morris is the manifesto: plain red brick, a practical asymmetrical plan following its rooms, and hand-crafted fittings throughout.[1, 3]

The buildings & the makers

Follow the reformers building by building: Morris and Webb's honest Red House; Horta and Guimard turning iron into flowering plants on the streets of Brussels and Paris; Gaudí's wholly personal Barcelona; Mackintosh's cool Glasgow restraint; and Sullivan's skyscrapers handing on to Wright's low, open Prairie house — the doorway to the modern.[1, 2, 4]

Morris and the Red House

The Arts and Crafts movement began as much in the workshop as on the drawing board. William Morris's firm made textiles, wallpaper, furniture and stained glass by hand, to a high standard, as a moral stand against machine shoddiness. Philip Webb's Red House at Bexleyheath (1859), built for Morris, put the ideals into brick: an L-shaped plan shaped from the inside out by its rooms, honest red-brick walls, steep tiled roofs, and craftsmanship everywhere. Its influence ran worldwide — including into the bungalow and into thoughtful colonial-era domestic building in India.[1, 3]

Vocabulary

Key terms

Arts and Crafts movement

The reform movement (Ruskin, Morris, Webb) championing honest hand-craft, good materials and truth to construction against machine production.

Truth to materials

The principle that a material should be shown honestly as what it is, and construction expressed rather than disguised.

Art Nouveau

The c. 1890–1910 'new art' style of sinuous, organic, nature-derived lines, seeking a modern style free of historical revivals.

Whiplash line

Art Nouveau's signature curve — a long, sinuous, asymmetrical line drawn from plant stems and tendrils.

Gesamtkunstwerk

A 'total work of art' — a building designed as a single unified vision, down to its furniture and fittings.

Form follows function

Louis Sullivan's dictum that a building's form should express its purpose and structure; the rallying cry of modern architecture.

Chicago School

The 1880s–90s architects (Jenney, Sullivan, Burnham & Root) who developed the steel-framed tall office building.

Organic architecture

Frank Lloyd Wright's ideal of buildings integrated with their site and nature, with open, flowing, horizontal space.

Apply it

Study task

Take one everyday object or building detail you can find — a gate, a railing, a chair, a lamp — and redraw it twice: once in the honest Arts and Crafts spirit (plain, sturdy, the construction shown), and once in the Art Nouveau spirit (one continuous, sinuous, plant-like line). In a sentence, say which feels more "modern" to you, and why.

In a nutshell

Recap

Around 1900 several movements reacted at once to industrialisation and the engineers' 'styleless' iron sheds.
The Arts and Crafts movement (Ruskin, Morris, Webb's Red House) preached honest hand-craft and truth to materials against machine shoddiness.
Art Nouveau (Horta, Guimard, Gaudí, Mackintosh) sought a genuinely new style in nature — the sinuous whiplash line — and bent the engineer's iron into organic beauty, often as a 'total work of art'.
In Chicago, Sullivan's 'form follows function' gave the tall building its own logic, and his pupil Frank Lloyd Wright reinvented the house as low, horizontal, open 'organic' space — the doorstep of the Modern Movement.

The road ahead

Where this course goes next

Sullivan's slogan and Wright's open space set the stage. Unit IV is the Modern Movement itself — the Deutscher Werkbund, Gropius and the Bauhaus, Le Corbusier's Five Points, and Mies van der Rohe's "less is more" — as architecture strips ornament away and rebuilds itself around function, space and the machine.
