What material is commonly associated with Brutalist architecture?

The material commonly associated with Brutalist architecture is raw concrete.

Brutalism emerged internationally in the 1950s, especially in postwar Britain, where architects sought direct, economical construction rather than decorative historical styling. Its buildings commonly expose structural systems and leave materials visibly unfinished, making raw concrete the style’s most recognizable material.

The architectural vocabulary is closely linked to the French phrase béton brut, meaning “raw concrete.” Le Corbusier’s use of exposed concrete, particularly at the Unité d’habitation in Marseille, strongly influenced later Brutalist designers. Concrete could be poured into molds, reveal the marks of wooden formwork, and create massive geometric forms at comparatively low cost.

Concrete is not the only material Brutalist architects used. Brick, steel, glass, timber, and stone also appear, and some examples are described as brick Brutalism. The key idea is not simply heaviness or ugliness, but the honest display of materials, structure, and function. That is why “raw concrete” is the standard quiz answer, even though individual Brutalist buildings may use several materials.
