Claims (7)
- The fifteen properties form coherent clusters reflecting deep structural interdependencies rather than independent design principles.
- Iba Takashi's visualization demonstrates correspondence among Alexander's 15 properties.
- Six Alexander Properties (symmetries, shape, contrast, gradients, void, simplicity) are structural-aesthetic refinements beyond coordination.
- The 15 Properties checklist is implementable and scales beyond Alexander's original small-N book studies.
- The 15 properties of aliveness operationalize Alexander's conceptual framework into measurable LLM response dimensions.
- The 15 structural properties decompose aliveness into inspectable formal components measurable on individual responses.
- The 9 cognitive-glue properties express the same phenomenon as Alexander's 15 Properties from the coordination side rather than aesthetic side.
Findings (4)
- Correspondence analysis reveals four clusters of related properties: Cluster 1 (Contrast, Not-Separateness, Roughness, Alternating Repetition, Good Shape), Cluster 2 (Local Symmetries, The Void, Levels of Scale, Good Shape, Positive Space), Cluster 3 (Boundaries, Strong Centers, Deep Interlock and Ambiguity), Cluster 4 (Simplicity and Inner Calm, Echoes, Gradients, Positive Space).Statistical grouping of properties based on dependency patterns, enabling deeper understanding of their coherence and interaction.
- Correspondence analysis reveals four major clusters of fifteen properties with overlapping membership.
- Five-story apartment building in Tokyo complements site wholeness through 50 structure-preserving steps that accentuate Y-configuration, positive space, levels of scale, and sunny southern orientation.Architectural example of harmony-seeking computation as iterative process where each design step strengthens latent structural features of the site.
