Now comprehensively updated and revised, this is a completely authoritative guide on how to look after your old house, whether its a timber framed medieval cottage, an eighteenth century urban terrace or an example of Victorian or Edwardian speculative development. Taking its lead from the Society for the Protection of Ancient Buildings (who have approved and authorised this volume), the books approach is one of respect, restraint and repair rather than restoration which can so easily and permanently destroy the rich historical legacy of any old building. Providing richly and deeply informed practical guidance on everything from breathability and damp to structural movement, roofs, windows and doors. This is the essential reading for anyone with an old house in need of any kind of repair or maintenance.
