JWRC Conservation was established by Jonathan Ratter in 2005 and has now completed over 250 projects. We are based in north-west England and in Orkney but have experience of working throughout the British Isles, from Jersey to Shetland. We specialise in buildings made with traditional natural materials and prefer to specify similar compatible materials for repairs and maintenance.

Jonathan studied the history of vernacular architecture and nineteenth century architecture and design before working for several years on the re-survey of listed buildings and as a list review and spot-listing consultant to English Heritage. He qualified as a building surveyor while working for one of the first surveyors to be accredited in conservation and spent five years as Building Conservation Officer for the Yorkshire Dales National Park Authority. After returning to private practice he was employed by several firms, including an international construction consultancy, before establishing JWRC. His knowledge of building history and construction and experience of preparing the statutory lists, as well as time spent working as a conservation officer and as a surveyor in private practice give him a broad understanding of building history, construction and defects, and of the heritage planning system.

He is a full member of the Institute of Historic Building Conservation, a Chartered Building Surveyor, and a member of the Society for the Protection of Ancient Buildings, the Building Limes Forum, and the Scottish Ecological Design Association.
