8 Pine Walk Carshalton SM5 4HB

1. 1.The proposed two storey rear extension, by virtue of its cumulative scale, excessive massing, and height, would result in an overdevelopment of the plot that fails to respect the original proportions of the host building, which has already been significantly enlarged. In design terms, the continuous projection creates a deep, stark, and unremitting side flank elevation lacking adequate architectural detailing, visual break-up, or subservience to the main dwelling. The proposal would therefore result in a dominant and disproportionate addition that severely harms the visual amenities of the host building and compromises the suburban character and spatial distinctiveness of this Area of Special Local Character, contrary to Policies 28 and 30 of the Sutton Local Plan (2018).
2. 2.The proposed two storey rear extension, by virtue of its depth, height, would represent an unacceptably overbearing and dominant form of development that results in a sense of enclosure and a loss of outlook for the occupiers of both No. 6 and No. 10 Pine Walk. Furthermore, given the site's orientation due south of No. 6 Pine Walk and the absence of a professional daylight and sunlight assessment, the scale of the structure would result in an unacceptable loss of daylight and overshadowing to the rear windows and private amenity space of No. 6, which features a truncated rear garden. The proposal is therefore detrimental to residential amenity, contrary to Policy 29 of the Sutton Local Plan (2018).
