18 Ballards Lane London N3 2HA

1. 1.The proposed first-floor rear extension, by reason of its excessive depth, scale, bulk and siting, would result in harm to the significance of the locally listed building through the loss and obscuring of the characteristic catslide roof form, an important feature contributing to the significance of the non-designated heritage asset. Furthermore, the extension would fail to appear as a subordinate and proportionate addition to the host property and would constitute an incongruous and overly dominant form of development that would detract from the character and appearance of the host building and surrounding area. The proposal is therefore contrary to Policies CDH01, CDH05 and CDH08 of the Barnet Local Plan, the Sustainable Design and Development Guidance SPD (2026), the design policies of the London Plan and Section 20 of the National Planning Policy Framework.
2. 2.The proposed development would fail to provide an acceptable standard of residential accommodation for future occupiers. Flat 1, by reason of its reliance on ground-floor habitable room windows facing directly onto Hervey Close, would be subject to undue overlooking and an unacceptable loss of privacy from passing pedestrians. Furthermore, Flats 4 and 8 would fail to achieve the minimum floor-to- ceiling height of 2.5 metres across at least 75% of the Gross Internal Area of each dwelling, resulting in substandard internal living conditions. In addition, Flat 8, by reason of its reliance solely on rooflights to serve all habitable rooms, would fail to provide future occupiers with an adequate level of outlook and visual connection to the surrounding environment, resulting in unduly constrained living conditions. Consequently, the proposal would fail to provide a high-quality residential environment and an acceptable standard of accommodation for future occupiers, contrary to Policy CDH01 of the Barnet Local Plan, the Sustainable Design and Development Guidance SPD (2026), and Policy D6 and the residential quality objectives of the London Plan.
3. 3.Insufficient information has been submitted to demonstrate that future occupiers of the proposed residential accommodation, particularly Flat 8 at third-floor level, would not be adversely affected by odour and emissions arising from the existing commercial kitchen extraction system serving the ground-floor restaurant. As such, the Local Planning Authority is not satisfied that the proposal would provide satisfactory living conditions for future occupiers. The proposal is therefore contrary to Policy CDH01 of the Barnet Local Plan, the Sustainable Design and Development Guidance SPD (2026), and the residential quality objectives of the London Plan.
