Brutalist Architecture

Published 26 November 2020 · Updated 13 November 2026

The gist: Brutalism made structure, materials and the organisation of buildings unusually visible. Exposed concrete became its most familiar expression, but the movement cannot be reduced to heavy façades or small windows. Its strongest works reward closer attention to circulation, light and shared space, from major public buildings to carefully planned homes.

Brutalist buildings are often judged at a distance: a photograph of a concrete wall, a deep shadow or an imposing silhouette. Those views capture part of the architecture. They say much less about how a building is put together or what it offers the people moving through it.

More than a concrete finish

Brutalism emerged within postwar modern architecture, but its early history was not simply a search for massive concrete forms. Alison and Peter Smithson’s school at Hunstanton, completed in 1954, used a welded steel frame, extensive glazing and visibly expressed services. The Twentieth Century Society connects its New Brutalist approach with directness about materials and construction.

This is a useful corrective to the idea that a building becomes Brutalist by looking heavy. A legible structure, the treatment of ordinary components and the relationship between the building’s organisation and its outward appearance can matter as much as its surface texture.

A public building as a landscape

Denys Lasdun’s National Theatre in London, opened in 1976, makes a different proposition. Its layered concrete forms bring the scale of the theatres into contact with the smaller scale of pedestrian movement. The building is encountered through changes of level, approaches and gathering spaces, as well as from across the river.

The distinction is important when assessing monumental architecture. A large building can contain places of intimacy; a dramatic exterior can conceal a carefully considered sequence of spaces. The question is how convincingly the design connects those scales.

Marseille: a building for collective life

Le Corbusier’s Unité d’Habitation in Marseille, also known as the Cité Radieuse, opened in 1952. Its significance extends beyond exposed concrete. The scheme combined apartments with internal circulation routes, shops and communal facilities, while the roof accommodated recreation and a nursery school.

The apartment loggias also complicate the stereotype of a closed concrete block. They create depth between inside and outside, with glazing and sun-control elements designed to respond to changing conditions. The project joins private accommodation to collective infrastructure; its architectural form is inseparable from that ambition.

Canberra: concrete with different scales

The National Gallery of Australia, led by architect Colin Madigan and opened in 1982, is a major Australian example. Bush-hammered concrete gives its surfaces a deliberately textured character, while the galleries progress through spaces of differing heights and sizes.

The Gallery describes a balance between public display, conservation and the practical needs of the institution. That is a useful way to read the building: its sculptural exterior houses a demanding programme. The experience changes between large rooms, more intimate galleries and the surrounding gardens. One material does not produce one uniform atmosphere.

A house in the bush

The Harry and Penelope Seidler House in Killara, completed in 1967, brings exposed concrete into a domestic setting. Designed by both architects, it steps through four levels on a steep bushland site. Half-flights of stairs connect the levels and create views between rooms and towards the landscape.

Timber ceilings and stone floors accompany the concrete. Rather than reducing the Seidlers’ broader modernist work to a single style label, the house is useful for showing how weight, material contrast and spatial openness can coexist. The experience inside is more complex than the exterior’s geometric massing might suggest.

Looking beyond the silhouette

To understand a Brutalist building, follow its routes, look at its junctions and notice where people can pause. Consider how the structure admits light and frames its surroundings. Those observations provide a firmer basis for judgement than assuming that exposed concrete is either inherently hostile or inherently virtuous.
