Louis Sauer is known in the US as one of the greatest housing experts. He achieved national fame when many of his innovative designs were built in Society Hill, the historic colonial neighborhood in Philadelphia. The quality, variety and reasoning behind his creative solutions for the renewal of large areas of old and derelict urban context were the exemplars for those who followed him in this field. The five designs included in this book are selected from the period (1961-79) when Sauer practiced in Philadelphia. His work is exceptional for its variety and wealth of solutions. Some examples are his modernistic forms, intelligent understanding of the history of the locale and the requirements of diverse urban scales. The five works Antonino Saggio is presenting in this publication give a picture of his outstanding design and the ingenuity of his solutions when faced with diverse design challenges and scales.
