Material

A grid is a systematic grouping of lines and planes, altogether forming a variety of different sized squares/geometries between their points of intersection. Grid is commonly seen in brutalist architecture.

Shape

Shape refers to the variety of 2-dimensional shapes that can be drawn from any given piece of architecture. It reflects familiarity, structure, and simplicity.

Brutalist architecture often incorporates square and rectangular shapes. This is largely due to its simple nature and ability to seem massive and strong.
