Why it was refused

The proposed plans fail to accurately depict the development as built, with the rear dormer roof extension constructed at a larger scale than shown. In addition, the application description does not fully identify all elements requiring retention, including the gable end roof alteration. The Local Planning Authority is therefore unable to properly assess the impact of the development contrary to Policies CDH01 and CDH05 of the Barnet Local Plan (2025) and Policy D3 of the London Plan (2021).
The roof extension, by reason of its design, scale and cumulative impact with existing extensions, appears incongruous and harms the character and appearance of the host property and surrounding area. The proposal is therefore contrary to Policies CDH01 and CDH05 of the Barnet Local Plan (2025), Policy D3 of the London Plan (2021) and the Council's Sustainable Design and Development Guidance SPD.
The submitted plans do not accurately reflect the development as built, including the scale of the rear dormer extension. As a result, the Local Planning Authority is unable to properly assess the impact of the development on neighbouring amenities, including overlooking, loss of privacy, outlook and visual intrusion. In the absence of accurate as-built drawings, the proposal fails to demonstrate compliance with Policies CDH01 and CDH05 of the Barnet Local Plan (2025), Policy D3 of the London Plan (2021), and the Council's Sustainable Design and Development Guidance SPD.

From the council's decision notice.
