Change of use of ground floor from A3 (restaurant) to A1 (retail) and erection of a first floor rear extension to provide 2 self contained residential units with refuse area to rear following demolition of two single storey storage units.
The proposed first floor rear extension by reason of its design, scale, bulk and elevated siting would appear as a visually dominant and discordant addition that would fail to be subordinate to or respectful to the character of the site and would be an obtrusive feature when viewed from neighbouring gardens. The proposal is therefore contrary to Policy 28 of the Sutton Local Plan 2018 and the advice in Supplementary Planning Document 4: The Design of Residential Extensions.
The proposed first floor rear extension by reason of its elevated position, height, depth and scale and proximity to the boundaries would result in harm to the amenity of residents at No's 1 and 3 St James Road by way of loss of outlook and increased sense of enclosure. The proposed extensions would therefore be contrary to Policy 29 of the Sutton Local Plan 2018.
The proposed development would provide a cramped and unsatisfactory living conditions for the future occupiers of the proposed ground floor flat and first floor flat by reason of limited floor ceiling heights. The proposal would therefore be contrary to Policy 3.5 of the London Plan 2016, Policy 9 of Sutton's Local Plan 2018, and The Mayor's Housing SPG 2016.
Without any evidence to demonstrate otherwise, the proposed development is unacceptable on highway grounds given that insufficient information has been provided to demonstrate that the lack of off street car parking would be mitigated against to prevent any unacceptable increase in on street car parking resulting in harm to the transport and highway network. The application is therefore contrary to the requirements of Policies 36 and 37 of the Sutton's Local Plan and appendix 11 of the Sutton Local Plan.
Without evidence to the contrary, the application has failed to provide evidence that the proposal will provide a satisfactory reduction in carbon emissions, sustainable drainage measures and water efficiency measures. As such, the application would be contrary to Policies 5.2 and 5.13 of the London Plan 2016 and Policies 31, 32 and 33 of the Sutton Local Plan 2018.
