Facade-retention schemes are being used more and more as a means of providing modern accommodation for commercial and industrial buildings in conservation areas and city centres. This book is the first authoritative guide to this highly complex technique and deals with the key issues associated with building behind historic facades. It explains the criteria that should be used by architects and others in developing successful designs, and gives an insight into the technical problems. It includes comprehensive descriptions of eight recent schemes, illustrated by numerous detailed drawings and photographs.
