This timely volume brings together fourteen case studies that address the challenges of conserving the twentieth century's most ubiquitous building material-concrete. Following a meeting of international heritage conservation professionals in 2013, the need for recent, thorough, and well-vetted case studies on conserving twentieth-century heritage became clear. Concrete: Case Studies in Conservation Practice answers that need and kicks off a new series, Conserving Modern Heritage, aimed at sharing best practices. The projects selected represent a range of building typologies, building uses, and project sizes, from the high-rise housing blocks of Le Corbusier's Unite d'Habitation and public buildings such as the London's National Theatre to small monuments such as the structures at Dudley Zoological Gardens and a sculpture by Donald Judd.
