Brutalist Architecture vs International Style
ブルータリズム建築 / インターナショナル・スタイル
Both sit in Modern Architecture, so the question is not what they belong to but how they behave. Both are read here as style. They are reached for with some of the same intent, which is where they get confused.
Brutalist Architecture

A postwar ethic of public building that leaves béton brut exposed and hides neither structure nor services. Bound up with the ideals of the welfare state, it is now the subject of preservation campaigns.
International Style
Strips ornament and aims at a universal architectural language crossing borders: the box, the free plan, steel, concrete and glass.
| Brutalist Architecture | International Style | |
|---|---|---|
| Era | 1950s–1970s | 1920s–1960s |
| Family | Modern Architecture | Modern Architecture |
| Kind | Style | Style |
| Cues | Raw exposed concrete / Massive volumes / Exposed structure / Repeating units | Rectangular volumes / Glass planes / No ornament / The free plan |
| Best used for | Giving a lasting face to public buildings such as universities and libraries · Making a building whose services and structure explain how it works | Corporate headquarters and civic buildings that must earn trust through proportion, not ornament. · Long life offices and galleries whose partitions move as programs change. |
| Type | Cast or incise signage into the same surface as the concrete | Align sans serif signs to the column grid, flush with the wall. |
| Composition | Divide large masses into repeated units and expose circulation outside | Carry floors on columns so plan and facade both stay free. |
| Material | Leave board marks, tie holes and joints as the finish | Steel and concrete frame, white rendered planes, large sheets of glass. |
| Caution | Applying a rough grey surface without designing drips and water paths leaves black streaks within a few years and the building simply reads as damaged. | A white box alone misses the structure, free plan, industrial materials and social program, and ornament stripped without tuned proportion and detail reads as cheapness, leaving openings with no reason for their position. |
