We are independent consultants who work as a team, bringing together a unique blend of multi-disciplinary skills, experiences, expertise and talent.  We essentially advise and negotiate the management of change to the historic environment - especially with regard to buildings.  We work with a number of other professionals who contribute valuable expertise in more specialist areas such as historic landscapes, structural engineering and planning. 


As independent third party advisors on all matters heritage-related, we are fully committed to the conservation of heritage assets, and our assessments are therefore honest and unbiased.  We are fully aware of the variety of different conservation philosophies adopted by those in the world of heritage and planning.  We subscribe to the approaches favoured both by Historic England and by the Society for the Protection of Ancient Buildings (“SPAB”) in terms of balancing the management of change with conservation and repair on a case-by-case basis.
