Why it was refused
- The proposed single storey rear extension by reason of its size, siting, bulk, height and excessive rearward projection along the boundary, would appear overbearing and visually obtrusive and result in an increased sense of enclosure, tunnelling effect and undue loss of outlook to the rear habitable rooms and garden of No. 31 Monks Avenue, to the detriment of the residential amenity of the neighbouring occupiers, contrary to Policy D3 of the London Plan (2021), Policies CDH01 and CDH05 of the LB Barnet Local Plan (2025) and the Residential Design Guidance SPD (2016)
From the council's decision notice.
