The proposed alterations change what is currently a subordinate extension (by virtue of its height, design and window arrangement) into the most dominant part of the house. The proposed false mansard would sit awkwardly with the roof form of the main building and, given its steep fa╪ade, would sit prominently in the streetscape. The alterations push the balustrading uncomfortably into other aspects of the fa╪ade and the large window to the front adds to the dominance and exacerbates the issues listed above by making it seem like a separate dwelling.
Views from The Little Boltons of the currently subordinate addition would be replaced by what would appear as a contrived and incongruous singular semi-detached dwelling. In addition, views of the trees, traditional butterfly roof forms, and rear elevations of properties on Cathcart Road would be expunged. Such development would be in contradiction with policies CL1, CL2, CL3, CL6, CL8, CL9, and CL11 of the Local Plan (2019).
