  We use our past professional and practical experience to help those with live projects...

Consultancy commissions include work for developers of housing, commercial office and regeneration projects. We have successfully provided 'plug-in' business-to-business conservation services for fellow professionals such as commercial architects whose wider projects have included an historic building.

CDAC's consultancy work is based upon knowledge gained from our own past projects which include a variety of works for The National Trust, ecclesiastical work carried out in association with English Heritage, domestic work for private individuals and works for charity organisations in connection with public grants.

Our present consultancy is also informed by a range of past conservative repair projects and hands-on conservation work carried out to the standards required for professional conservation accreditation.

  Old buildings used different technology and served different ways of life, their adaptation to modern
   use can often be more satisfactorily achieved through understanding rather than overwhelming them.

   Their antiquity may also give them enhanced value: age and character translating into financial worth -
   despite some limitations in performance - making it logical to understand and preserve true character.

The directors of CDAC have been actively involved in national and local conservation issues during their careers, serving on committees of professional bodies and conservation organisations.

They have written extensively - books, magazines and websites - to share lessons learnt from building conservation and to highlight its relevance to the modern pursuit of sustainability.

They are keen to make this information more widely available and understood through work in architectural and general education, talks and lectures, and by contributing to broadcasts and websites - please see for more.
