Solid-void theory “holds that the volumetric spaces shaped or implied by the placement of solid objects are as important as, or more important than, the objects themselves.

A three dimensional space is considered a positive space if it has defined space and a sense of boundary or threshold between inside and out. Positive spaces can be defined in an infinite number of ways by points, lines, planes, solid volumes, trees, building edges, columns, walls, sloped earth, and innumerable other elements.”
