Recent contracts include Timber Conservation Consultant for the World Monuments Fund where he surveyed Aba Jifar Palace, Ethiopia and produced a condition report, schedule of repairs and set out a conservation training programme.

In 2007, he made the move from being a very successful self-employed restoration carpenter to becoming a historic building surveyor for the National Trust, Europe’s largest conservation charity. His twenty years’ of ‘hands on’ building experience gave him a varied and firm skill base to allow a smooth transition into the field of historic building surveying. He quickly honed his skills, becoming competent in surveying, specification writing, condition reporting, project management and budget control. 

Within the first three years of working for the National Trust in Wales, he was entrusted with a £1 million budget to project manage an environmental compliance programme to include all of the National Trust Wales building stock. He wrote all the planning and building regulation applications for submission to the relevant Local Authorities and the Environment Agency (now part of Natural Resources Wales). He then project managed all the works to ensure that all the planning and building requirements were adhered to.

Following the above programme, he continued to hone his surveying skills through looking after properties across Pembrokeshire and Ceredigion. He was responsible for projects of all sizes including short and long term cyclical works to buildings like Llanerchaeron Villa near Aberaeron, Tudor Merchant House in Tenby and St David’s Cross in St David’s City to name a few. He was also a key project member when the National Trust acquired Treleddyd Fawr, a 17th century Pembrokeshire cottage near St David’s. He wrote the condition report for the cottage and calculated the five year and ten-year forecast figures which helped secure this nationally significant and unique cottage. In 2014, he moved location to become Project Building Surveyor in the newly established South East Wales region of the National Trust, working at both the 17th century Tredegar House and grade I listed Dyffryn Gardens. Here he managed short and long-term cyclical works and project budgets, whilst also carrying out several condition reports and listed building consents.
