About this application

This is a planning application for a single storey rear extension at 94 Grosvenor Avenue Carshalton SM5 3EP. Sutton has handled 3,881 applications of this type. This one was decided in 39 days, 2 weeks quicker than Sutton's typical decision time. The site is in a conservation area, with 1 listed building nearby. There has been 1 other application at this address. We hold 645 applications in total for the SM5 postcode area.

Why it was refused

  1. The proposed single storey rear extension, by reason of its excessive depth and height in proximity of the boundary with No. No. 92D and No. 96 Grosvenor Avenue and along a large section of their rear gardens, would result in a visually intrusive addition that would have an adverse impact on the amenity of these adjacent properties by way of a loss of outlook and creation of an un-neighbourly sense of enclosure as viewed from the primary first floor windows and rear gardens of these properties. The proposed development is therefore contrary to Policy 29 of Sutton Local Plan 2018, guidance provided within Sutton's Supplementary Planning Document 'Design of Residential Extensions' (SPD4) and paragraph A.4 (7) of Schedule 2, Part 1, Class A of the Town and Country Planning (General Permitted Development) (England) Order 2015 (as amended).

From the council's decision notice.
