Conservation Architecture

Camillin Denny Design are constantly surprised by the misguided assumption that work within listed properties is very limiting and that ‘the planners’ will be very reluctant to allow anything to be done. Both Mark and Liam have also been surprised that clients and commentators alike find it extraordinary that their modern style can be so successfully integrated and permitted as part of the works to a listed property.

Liam Denny believes that ‘People often think that a listed property has to remain frozen in the period in which it was built.’ He goes on to say that he feels that ‘that’s unrealistic, as from the point it was first occupied it started to be changed, adapted and amended to suit the use of the occupants at that time. Over 200 years, for example, a lot of changes will have occurred, making it near on impossible to ever know exactly what the property was like when it was first constructed.

What is important with a listed building is to understand the layering, knowing what is important to the historical sense of the property and respecting and where possible protecting and restoring those elements. By working with historical experts and local conservation officers, Camillin Denny’s approach is to understand and document the current condition of the building and to fully comprehend its history so that we can add further new layers to the rich tapestry that has been created over time. These new interventions can and should be a more contemporary layering of fabric that is more suited and more commensurate to the way the building will be used today.’

Camillin Denny have worked on a multitude of Grade I, II and II* Listed projects including the Grade II* Listed; Old Irish Club at 82 Eaton Square in Belgravia, London, a Grade I Listed Robert Adams house in Hertford Street, Mayfair and Grade II Listed—The Grove in Highgate, and a number of Listed Regency projects in Brighton and Hove. Of particular significance is their conversion of the Grade II Listed St Stephens Church in central Brighton to a homeless day Centre for Brighton Housing Trust.
