Why it was refused
- The proposed development, by reason of its scale, form and siting, would result in an overly dominant and unsympathetic roof extension that fails to respect the character, appearance and established roofscape of the host dwelling and the wider street scene. The wrap-around dormer, extending across the front, side and rear roof slopes, would appear excessively bulky and incongruous, eroding the form of the existing hipped roof and unbalancing the symmetry of the semi-detached pair. The siting of a prominent dormer on the side roof slope, which would be highly visible from the public realm, would be out of keeping with the prevailing pattern of development within St Margarets Drive, where such features are not characteristic. The proposal would fail to appear subservient to the host dwelling and would have a harmful impact on the visual amenity of the street scene and surrounding area. As such, the proposal is contrary to Policy BCS21 of the Bristol Core Strategy (2011) and Policies DM26 and DM30 of the Bristol Site Allocations and Development Management Policies (2014), as well as the guidance contained within SPD2: A Guide for Designing House Alterations and Extensions.
From the council's decision notice.
