Not-Separateness
extends
The property that a living whole is at one with the world, not separate from it; the center melts into its surroundings, the boundary is fragmented or incomplete, and there is a profound connection rather than isolation—perhaps the most important property of all
The Void
extends
The property that the most profound centers have at their heart a void like water, infinite in depth, surrounded by and contrasted with the clutter around it; the calm emptiness needed by every center to give it the basis of its strength
Alternating Repetition
extends
The property that living repetition is not simple repetition but alternation where a second system of centers repeats in parallel, creating counterpoint; what is really happening is oscillation, like waves
Contrast
extends
The property that living structures contain intense contrast—far more than one imagines helpful; true opposites which annihilate each other when superimposed, creating differentiation that gives birth to something; contrast unifies rather than separates when used correctly
Good Shape
extends
The property that a good shape is a center made up of powerful intense centers which themselves have good shape; built up from elementary figures with high internal symmetries, bilateral symmetry, a well-marked center, compactness, and closure
LOCAL SYMMETRY
extends
One of Alexander's fifteen properties; appears in birthday table, handshake, and namaste examples

Fifteen Properties of Living Structureframework0.839
The set of geometric properties that appear in all living structure: levels of scale, strong centers, boundaries, echoes, gradients, deep interlock and ambiguity, local symmetries, roughness, inner calm, not separateness, and others.
The fifteen properties necessarily accompany the centers and symmetries in living structure.claim0.831
The fifteen properties are the fifteen ways in which centers can enliven one another.claim0.804
Recapitulation of the Book 1 definition, linking the properties to the mutual intensification of centers.
Living centersconcept0.795
Coherent spatial wholes that emerge from living processes; they are the building blocks of environments that foster belonging
The fifteen properties, the field of centers, and the wholeness thoroughly and completely determine the way that buildings work.claim0.794
Universality claim that the same geometric properties govern both beauty and function.
The fifteen properties arise because they are the principal ways in which centers can be strengthened by other centersclaim0.788
Central interpretive claim of the chapter: the fifteen properties are not independent observations but all reduce to ways that centers help each other come to life in space
And while this is going on—as in nature—the fifteen properties that give life to the emerging centers develop easily.claim0.786
Claim that the fifteen properties emerge naturally from unfolding.
The fifteen properties are the ways centers sustain each other's coherence, thereby contributing to the stability and robustness of natural systems.claim0.782
Proposed as the reason the properties appear in functionally stable or semistable systems.
