This comprehensive study of roofs provides a huge amount of detailed information for architects and building professionals, but it also has much to offer lay interests. The historical perspective: a wide selection of roofs from the most classical to the most avant-garde reveals the transition they went through in terms of style, functionality and material. The book also provides a thorough, up-to-date study of trends in roof design, according to type, use and their respective characteristics. Works by leading architects are included, as well as some from a younger generation, all of them fully illustrated with plans and building details which help to give a better understanding of the enormous range of possibilities that exist in roof design in contemporary architecture.
