2 And 2A Mountfield Road London N3 3NB

1. 1.The proposed changes to the roof of the host site by way of increasing the size, massing, scale and design of the roof through a hip to gable end extension, increase in roof massing and front, side and rear dormer would result in a detrimental and overbearing massing to the roof which neither respects nor enhances the character of both the host dwelling and the street scene. The resulting extensions would be contrary to the high quality design aspirations of the NPPF (2024), Policy D3 of the London Plan (2021), Policies CDH01 and CDH05 of the LB Barnet Local Plan (2025) and the Sustainable Design and Development Guidance SPD (2026).
2. 2.The sub-division of the property to form 5no. self-contained flats would result in an over intensification of the host property which would harmfully increase noise, disturbance, and disruption to neighbouring residents through increased coming and goings and associated general activity, incongruous to the established pattern of development and detrimental to the residential amenities of neighbouring occupiers, contrary to Policies D3 and D14 of the London Plan (2021), Policies CDH01 and CDH05 of the LB Barnet Local Plan (2025) and the Sustainable Design and Development Guidance SPD (2026)
3. 3.The proposed scheme, by reason of its configuration, would overlook the adjoining garden spaces, particularly No 162 Regents Park Road, resulting in a loss of privacy, to the detriment of residential amenity of neighbouring occupiers, contrary to Policies D3 and D14 of the London Plan (2021), Policies CDH01 and CDH05 of the LB Barnet Local Plan (2025) and the Sustainable Design and Development Guidance SPD (2026)
4. 4.The sub-division of the property to form 5no. self-contained flats, by reason of its configuration, would result in poor stacking, poor outlook to habitable windows and unacceptable levels of overlooking of habitable room windows from communal areas, to the detriment of the residential amenities of future occupiers, contrary to Policy D6 of the London Plan (2021), Policies CDH01 and HOU03 of the LB Barnet Local Plan (2025), the Sustainable Design and Development Guidance SPD (2026)
5. 5.The proposal falls within an area identified in the West London Strategic Flood Risk Assessment as being at risk from surface water flooding and fails to provide a sufficient Flood Risk Assessment - demonstrating that the development within the site boundary, would be located on an area that would be at risk of flooding from any source, now and in the future (having regard to potential changes in flood risk). As such, insufficient information has been provided to ensure that the proposed development would not result in an increased risk of flooding elsewhere and remain safe for its lifetime particularly given the more vulnerable proposed use, contrary to the National Planning Policy Framework (2025), Policy SI 12 of the London Plan (2021) and Policy ECC03 of the LB Barnet Local Plan (2025).
