The local planning authority considers that, due to the proposals scale and dominance over the existing and surrounding dwellings', the proposal would appear incompatible with the existing building and would be an intrusive and incongruous feature within the street scene, to the detriment of visual amenity. For this reason, the proposal is contrary to saved Policies EV/1 and H/17 of the adopted Borough of Charnwood Local Plan (2004) and Policy CS2 of the Charnwood Local Plan Core Strategy which require that such development respects and enhnaces the character of the area, is of a design that is compatible with neighbouring buildings, is not intrusive or incongruous in the street scene and remains compatible in scale, mass and design with the original building. The proposal is also contrary to advice contained within the Borough Council's adopted Supplementary Planning Guidance on House Extensions (2001) and Supplementary Planning Document, Leading in Design (2006).
