Statistically significant differences among integration values for both small and great houses over time are demonstrated. Difference factor analyses identify a robust spatial structure for small houses. This strong structure is a result of differences in spatial integration between built space and built form, and between spatial functions. Great houses are found to have a much weaker spatial structure. The results of this research are used to evaluate the spatial implications of the currently proposed Chaco great house models.
Syntactical analyses suggest that it is unlikely that any one model fits all the great houses.
The small houses appear domestic in nature and organisation. Examining the social and spatial relationships of kivas and mealing bin rooms at both great and small houses seems a promising avenue for future inquiry.
