Erection of a mansard roof extension to London terrace in a Conservation Area


The dwelling was located within a short terrace of similar properties which was considered to make a positive contribution to the Conservation Area. The council refused the proposals on the basis that the mansard roof extension would interrupt the currently uninterrupted roof form to the detriment of the area, building and street scene.

The main issue for the appeal was whether the proposal would preserve or enhance the character or appearance of the Conservation Area. It was suggested that the significance of the site was from its group value and not just the immediate neighbouring properties.

Plande successfully argued that the proposals would complement rather than detract from the surrounding character and appearance and therefore not harm the Conservation Area or the existing building or broader street scene.

The appeal was allowed and our clients were able to construct their desired extension accordingly.
