Over the concluding decades of the twentieth century, the historic preservation community increasingly turned its attention to modern buildings, including bungalows from the 1930s, gas stations and diners from the 1940s, and office buildings and architectural homes from the 1950s. Conservation efforts, however, were often hampered by a lack of technical information about the products used in these structures, and to fill this gap Twentieth-Century Building Materials was developed by the U.S. Department of the Interior’s National Park Service and first published in 1995. Now, this invaluable guide is being reissued—with a new preface by the book’s original editor. With more than 250 illustrations, including a full-color photographic essay, the volume remains an indispensable reference on the history and conservation of modern building materials. Thirty-seven essays written by leading experts offer insights into the history, manufacturing processes, and uses of a wide range of materials, including glass block, aluminum, plywood, linoleum, and gypsum board. Readers will also learn about how these materials perform over time and discover valuable conservation and repair techniques. Bibliographies and sources for further research complete the volume. The book is intended for a wide range of conservation professionals including architects, engineers, conservators, and material scientists engaged in the conservation of modern buildings, as well as scholars in related disciplines.

CD-ROM contains: files for all of the plans, sections and elevations included in the book.

Focusing on architecture from all regions of the world, this three-volume set profiles the twentieth century's vast chronicle of architectural achievements, both within and well beyond the theoretical confines of modernism. Unlike existing works, this encyclopedia examines the complexities of rapidly changing global conditions that have dispersed modern architectural types, movements, styles, and building practices across traditional geographic and cultural boundaries.

The first half of the twentieth century witnessed a reaction in Cairo against the occidentalizing architectural trends which had prevailed in the nineteenth century and interrupted the natural evolution of Islamic architecture. This new study seeks to define the different trends of the Islamic Revival period and discuss their motivation, progress, and achievements. After a survey of the stylistic evolution and foreign influences in Cairene architecture until the end of the eighteenth century and a brief account of the nineteenth-century background to the Islamic Revival period, the author discusses the impact of architectural education, nationalism, and parallel styles on Islamic Revival architecture. Then, through the examples of a number of Cairo facades, he proposes for the first time a definition of five recognizable Islamic Revival styles: Neo-Islamic Revival, Modernized Islamic, Eclectic, Twentieth-Century Islamic, and Baroque Islamic (Heliopolis).
