This publication reveals for the first time the singular contribution that the architects George & Edward Blum made to the design of the New York apartment building. The Blums' buildings, designed between 1910 & 1930, are superbly embellished with complex brick patterning & are highlighted by unusual detail in terra cotta & art tile. This book investigates the influence of Parisian design on the Blums' work & places their apartment houses within the larger context of residential development in New York City. It also explores the varied designs & innovative handling of decorative materials found in these in buildings.
