It is the opinion of the local planning authority that, by reason of its design, mass, scale and height, the proposed extensions would substantially and unacceptably change the scale and character of the existing dwelling to the extent that it would appear over-dominant, discordant and incongruous in relation to the dwelling and the wider street scene. In particular, the scale and mass of the two storey extensions would not be subordinate in size and design to the existing dwelling, therefore forming an over dominant feature. Furthermore the unsympathetic window arrangement, would appear unbalanced, and would add the incongruity of the proposal. It would, therefore, would be severely detrimental to visual amenity. In this respect, the proposal is contrary to policies CS2 of the Charnwood Local Plan 2011-2028 Core Strategy, policies EV/1 and H/17 of the Borough of Charnwood Local Plan (2004) and the Council's adopted Supplementary Planning Document on Design (2020). These seek to ensure that extensions to dwellings are compatible in scale and design with the original and other dwellings and that they are not detrimental in terms overdominance.
