About this application

This is a planning application for an outbuilding at 51 Elder Road London SE27 9LY. Lambeth has handled 15,936 applications of this type. This one was decided in 56 days. The site is in 1 listed building nearby. There has been 1 other application at this address. In the past year there have been 60 applications across Knights Hill. We hold 1,060 applications in total for the SE27 postcode area.

Why it was refused

  1. The proposal would result in the loss of a property capable of providing family-sized accommodation, thereby causing harm to the local housing mix. In addition, it would fail to address an identified local need for the proposed housing type and would exacerbate the existing over-concentration of Houses in Multiple Occupation (HMOs) in the area. Such over-concentration has been linked to adverse impacts on the mix, balance, and well- being of the community, including increased incidents of anti-social behaviour. Consequently, the proposal is considered unacceptable in land use terms and is contrary to Policy H9 of the London Plan (2021) and Policy H9 of London planning@lambeth.gov.uk SW2 9QQ the Lambeth Local Plan 2020-2035 (2021).
  2. The conversion of the outbuilding to residential accommodation would result in substandard accommodation by virtue of the loss of privacy for future occupants, contrary to London Plan (2021) policy D6, and Lambeth Local Plan (2021) policy H5
  3. The proposed development would intensify the use of the site and result in an adverse impact on neighbouring occupiers through an increase in noise and disturbance. As such, the proposal is contrary to the objectives of policy Q2 of the Lambeth Local Plan (2021).
  4. In the absence of a S106 agreement, the application fails to mitigate the impacts of the proposed development, as such, the proposal is contrary to the objectives of policy D4 of the Lambeth Local Plan (2021).
