Why it was refused
- The proposed extensions, by reason of the depth of the ground floor, width of the first floor and combined scale, bulk, massing, design and siting of the two storey rear extension, scale, bulk and massing of the dormer roof extension, unbalancing effect of the hip to gable and height, scale, massing, design, fenestration and siting of the front extension, would result in a disproportionate and unsympathetic addition that would fail to respond sensitively to the established pattern of development and appear unduly incongruous, to the detriment of the character and appearance of the host property, street scene and surrounding area, contrary to Policies 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)
- The proposed two-storey rear extension, by reason of its scale, massing, design, excessive rearward depth and siting within close proximity to neighbouring boundary, would constitute an overbearing and visually obtrusive addition resulting in an unacceptable loss of outlook and increased sense of enclosure, detrimental to the residential amenities of the neighbouring occupiers at No 51 Wessex Gardens, contrary to Policy D3 of the London Plan (2021), Policies CDH01 and CDH05 of the LB Barnet Local Plan (2025) and the LB Barnet Residential Design Guidance SPD (2016)
From the council's decision notice.
