The local planning authority considers that, due to its size and siting, the proposed extension would be detrimental to the amenities of the occupiers of 79 Warwick Avenue due to over dominance, overshadowing and a substantial loss of light to the front ground floor window of the property. For these reasons, the proposal is contrary to the intentions of saved Policy H/17 of the adopted Borough of Charnwood Local Plan, which seeks to ensure that extensions to dwellings are not be detrimental to the amenities of occupiers of nearby properties, and also in conflict with the advice given on the design of extensions in the Borough Council's adopted Supplementary Planning Guidance on House Extensions.
