Why it was refused
- The proposed rear dormer, by virtue of its design, width, scale, window positioning and siting, would result in a visually awkward and uncharacteristic addition which is not suitably integrated or reflective of the host dwelling or the immediate street scene. Flat roof features do not form part of the original character of the locality and would therefore result in the proposed dormer being harmful to visual amenity. In addition, the proposed dormer would not accord with the guidance set out in the Residential Alterations and Extensions Guide SPSD 2017. The proposal would therefore be contrary to guidance in the NPPF, Policies CSTP22, CSTP23 and PMD2 of the Core Strategy and Policies for the Management of Development DPD (as amended) 2015 and the adopted Thurrock Residential Alterations and Extensions Design Guide (RAE) SPD 2017.
From the council's decision notice.
