Modern architecture (International Style)
A house as a machine for living: no ornament, function first, concrete, glass and the free plan

How to recognise it
- Smooth white or glass walls, no decoration
- Flat roof, often a terrace
- Ribbon windows across the facade
- Building lifted on slender columns
- Continuous glass curtain wall
Why it emerged
Reinforced concrete and steel frames freed walls from carrying loads, and postwar housing shortages demanded fast, cheap building. Bauhaus architects and Le Corbusier saw standardisation as a route to a fairer society; after 1945 the style became the idiom of corporations and new nations.
