It is the opinion of the local planning authority that, by reason of the size of the extension and its siting in close proximity to neighbouring properties, it would be an intrusive and over-dominant feature, to the detriment of the residential amenities of the occupiers of those properties. For this reason the proposal would be contrary to the intentions of policy H/17 of the adopted Borough of Charnwood Local Plan and policy CS2 of the Charnwood Local Plan 2011-2028. These policies seek to ensure that extensions to dwellings are compatible in scale and design with the original dwelling and that they are not detrimental in terms of overshadowing or overdominance of the adjacent property. In these terms, the proposal is also in conflict with the advice given on the location of extensions in the Borough Council's adopted Supplementary Planning Guidance on House Extensions.
