Fifteen Properties
The Fifteen Fundamental Properties/Transformations are a conceptual framework invented by Christopher Alexander and described at length in The Nature of Order. They describe certain empirically observable geometric properties in (built) space that are associated with Alexander's conceptualizations of "wholeness" and "life". They also represent structure-preserving transformations that take a region of space from a state of the given geometric property being weakly-expressed to being expressed more strongly.
