On territoriality and materiality:
"Second Empire architects also discouraged decorating practices that made domestic interiors resemble streets. In an article whose title – ”Des voies publiques et des maisons d’habitation à Paris” – signaled a conceptual separation between roads and houses, Charles Gourlier noted that within houses, wood parquet floors were replacing ”pavement” [dallages]. Formerly, slabs of concrete, stone, or marble had been used to cover floors inside apartments and to pave streets, but now they began to be confined strictly to the street. The street thus became a mineral realm whose hard, unyielding durability was perceptibly distinct from the more delicate, vegetal ground of the home."
