Concerning Buildings has been prepared in honour of Sir Bernard Feilden CBE, a leading and outstanding practitioner in the field of the conservation and repair of historic buildings for forty years or more, having originally studied architecture as a mature student at the Architectural Association after the Second World War (he was born in 1919). The book was not, however, intended to be about him, except for a warm tribute written by Professor Patrick Nuttgens and a full bibliography of his works compiled by Keith Parker: its purpose, rather, is to cover a co-ordinated and wide range of conservation issues, theoretical and practical, and to be regarded as a reference work for our position and our achievements in the art of conservation today. The book contains a wealth of interest and a mine of information for all who are concerned about the present state and approaches to the conservation of buildings in all parts of the world. It will be especially useful to those who teach, those who want to learn, those who own and manage old buildings, and those whose job it is to look after them.
