Historic Buildings (Listed and Unlisted)

The Historic Buildings team specialise in appraising buildings of all ages, types and states of repair. Very often a site might comprise a range of buildings dating from various periods. CgMs is well versed in assessing buildings from Medieval timber framed structures right up to 1970s Brutalist architecture. We are experienced in assessing the potential of a building for statutory listing and have supported both the listing and de-listing of various buildings with success.

CgMs deal with the setting of listed buildings and new development on a daily basis and is fully aware of the changing national policy and guidance involving listed building and their setting. The assessment of setting and impacts of new development upon it is open to many interpretations. The team are experienced in systematic assessment of the significance of a historic building and what land around it contributes to that significance.

We deal with unlisted buildings of local merit within and outside conservation areas and advise on the best way to secure planning and other consents. Below are a range of services with respect to buildings which CgMs provide.
