It is considered that the proposed development would result in less than substantial harm toward the character and appearance of the conservation area and the listed building it will be built upon. Meynell Lodge is a prominent and historically valued element of the Quorn Conservation Area, with the building containing a number of interesting, decorative features including ornamental chimney stacks and, in particular, a number of extremely interesting windows with Gothic arched glazing bars to the rear and side elevations. The front elevation also contains a number of horizontal sliding sash windows, commonly referred to as "Yorkshire" sliding sash windows, these are a rare and important type of window in the Borough. The proposed development would disrupt the form of the host dwelling, to the detriment of its appearance and value, as well as the contribution it makes to the character and appearance of the conservation area. The disproportionate proposed two storey extension would unbalance a historically significant site, which would in turn diminish the character of Meynell Road and the wider conservation area. The harm identified is less than substantial of which is not outweighed by the public benefits. The proposal is therefore considered to neither preserve nor enhance the character and appearance of the the Grade II Listed Building and the Quorn Conservation Area as required by sections 66 and 72 of the Town and Country Planning (Listed Building and Conservation Areas) Act 1990. The proposal is also contrary to policy CS14 of the Core Strategy (2015), the Quorn Conservation Area Character Appraisal and paragraph 202 of the NPPF which seek appropriate forms of development that conserve and protect heritage assets and their settings.

The proposed development would substantially alter the property's appearance, form and proportion and would introduce new fenestration detailing so that it would significantly differ from its original design. These changes would result in a dwelling which would be out of character with the surrounding area in terms of its appearance, form and design. It is considered that this would create an incongruous feature within the street scene that would be visually harmful. The proposed two storey extension diverts away from the prominent design features which characterise the dwelling. As a result, the proposal would fail to accord with policy CS2 of the Charnwood Local Plan (2011-2028) Core Strategy and saved Policies EV/1 and H/17 of the Borough of Charnwood Local Plan and Policy S2 of the Quorn Neighbourhood Plan which seek to ensure that new development remains is of good quality design and in context with the surrounding area. The proposal is also considered to be development of poor design that fails to improve the character and quality of the area and should therefore be refused in accordance with paragraph 134 of the National Planning Policy Framework (2019) and the National Design Guide (2019) and The Charnwood Design SPD (2020).
