After setting up his own office in London, he took over an established Lincoln office and became involved in conservation work, mainly on churches, but also on mud-and-stud buildings. He was a founder member of EMESS and was chairman for 15 years. He presented papers at the ICOMOS conferences of Terra 2000 and Terra 2012, both on the subject of how to carry out mud-and-stud construction to comply with the modern British Building Regulations.
