Which configuration of vertical planes generates a field of space from its corner outward?

The configuration of vertical planes that generates a field of space from its corner outward is best represented by an L-shaped plane. This form creates a defined area and opens up space as it extends away from the corner. The two intersecting planes connect at a right angle, effectively creating a boundary that allows for a flow of space diagonally inward or outward from the corner. This configuration is particularly effective in defining areas, influencing movement, and providing a spatial experience that is both intimate and expansive.

The L-shape allows for various spatial interactions, as it doesn't enclose space completely but leads the user into and through the area created. This characteristic is essential in architectural design for guiding movement and providing a spatial hierarchy.

In contrast, the other configurations would not generate a space in the same way. A U-shaped plane would define a more enclosed space, while parallel planes maintain a more linear and uniform distance without the dynamic flow of space that the L-shape offers. An overhead configuration, such as a roof or ceiling structure, does not directly relate to the generation of a spatial field but rather serves to enclose or protect the space beneath it. Thus, the L-shaped plane is most effective in creating an expanded sense of space from its corner outward.
