About this application

This is a planning application for a dormer extension at 111 And 113 Bridge Lane London NW11 9JT. Barnet has handled 16,929 applications of this type. This one was decided in 56 days. There have been 3 other applications at this address. We hold 1,891 applications in total for the NW11 postcode area.

Why it was refused

  1. The proposed front elevation alterations, including the dominating central gable feature, associated fenestration changes, garage alterations and visible elements of the front basement extension, by reason of their excessive scale, prominence, bulk, lack of subordination and incongruous design, would fail to respect the proportions, roof form and architectural composition of the host dwelling and would appear as a dominant and visually intrusive addition. The development would result in a top- heavy and disproportionate form of development that would disrupt the established building line and rhythm of the street frontage, causing harm to the character and appearance of the host property and the wider street scene. The proposal therefore conflicts with Policies CDH01, CDH05 and CDH06 of the Barnet Local Plan (2025), Policies D3 and D6 of the London Plan (2021), the objectives of the National Planning Policy Framework (2026), and Barnet's Sustainable Design and Development Guidance SPD (2026).
  2. The proposed basement accommodation would fail to provide an acceptable standard of living accommodation for future occupiers by reason of inadequate outlook and insufficient evidence demonstrating adequate natural light to the proposed basement bedrooms. In particular, Bedroom 2 would be served solely by a rooflight with no meaningful outlook, whilst Bedroom 1 would have a restricted outlook due to the relationship with the access ramp and potential associated changes in land levels. The submitted plans and sections fail to satisfactorily demonstrate that the proposed habitable rooms would benefit from acceptable levels of outlook, light and amenity expected of residential accommodation. As such, the proposal would provide substandard living conditions for future occupiers, contrary to Policies CDH01 and CDH06 of the Barnet Local Plan (2025), Policy D6 of the London Plan (2021), and Barnet's Sustainable Design and Development Guidance SPD (2026).

From the council's decision notice.
