9 Petworth Avenue Winstanley Wigan WN3 6JG

1. 1.The proposed single storey rear extension, by virtue of its design would result in an over dominant addition. The overall length, mass and continuation of the existing roof form would fail to appear subordinate to the host dwelling. The minimal separation distance to the existing detached garage would also create a continuous built form to the rear of the property, resulting in a loss of space between the adjacent residential plot to the rear. This would result in a poor relationship, creating harm to the character and visual amenity of the streetscene and contrary to Wigan Local Plan Core Strategy Policy CP10, Places for Everyone Joint Development Plan Policy JP-P1, the House Extensions Design Guide Supplementary Planning Document and the design objectives of the National Planning Policy Framework.
2. 2.The proposed single storey rear extension would significantly impact on the size and quality of private rear garden space available to any occupants of the dwelling. The remaining garden areas would not be as private as the current arrangement, being located to the front and side of the dwelling only and exposed to open views from the surrounding streetscene. As a consequence of the extension, the loss of usable private amenity space would be detrimental to the living conditions and quality of life currently provided by the existing design and arrangement of the dwelling within the plot. The development is therefore contrary to Wigan Local Plan Core Strategy Policies CP10 and CP17, the House Extensions Design Guide Supplementary Planning Document and the National Planning Policy Framework.
