The book consists of close comparative analyses of 28 modern buildings, two by two, in order to interrogate their spatial, constructive, envelopmental, and programmatic characteristics. Abstract In connection with the publication of Kenneth Frampton’s A Genealogy of Modern Architecture: Comparative Critical Analysis of Built Form, Thomas McQuillan conducted an interview in March of 2016 with Frampton to discuss the book’s background and the implications publication has for contemporary architecture.
