Why it was refused

The proposed single-storey side extension, by reason of its excessive width, limited setback from the principal elevation and prominent corner siting, would fail to appear as a subservient addition to the host dwelling. The extension would almost double the apparent width of the dwelling and would result in a dominant and visually intrusive form of development that would undermine the balance and architectural integrity of the semi-detached pair. Furthermore, the proposal would erode the open and spacious character of this prominent corner plot and fail to preserve or enhance the character and appearance of the Sea Mills Conservation Area. The prominence of the extension would be exacerbated by its relationship with the existing boundary hedge, which currently provides an important soft landscape feature and contributes positively to the verdant character of the street scene. The proposal raises concerns regarding the continued retention and effectiveness of this landscaping, the loss or diminution of which would further increase the visual prominence of the development. Accordingly, the proposal is contrary to Section 72 of the Planning (Listed Buildings and Conservation Areas) Act 1990, Policy BCS21 of the Bristol Core Strategy (2011), Policies DM26, DM27 and DM30 of the Site Allocations and Development Management Policies (2014), and the guidance contained within SPD2: A Guide for Designing House Alterations and Extensions.

From the council's decision notice.
