This generously illustrated study of factory buildings documents how these factories were designed to meet the multifarious demands of industry, argues that industrial aesthetic ideals were derived from functional engineering principles (what she terms the "engineering aesthetic"), and contrasts the factory designs of engineers and architects. As Bradley probes the rationale behind the design of factories, she offers readers a useful typology and clarifying terminology.
