Why it was refused
- The proposed single storey rear extension by reason of its siting and excessive rearward projection would be incongruous, inappropriate and out of context with the prevailing character of the host building and wider pattern of development. The proposed two-storey side extension would unbalance the terraced group of which it forms part and result in a terracing effect. The development would therefore be detrimental to the character and appearance of the property and streetscene and would fail to preserve or enhance the character and appearance of the Watling Estate Conservation Area, contrary to Policies D3 and HC1 of the London Plan (2021), Policies CDH01, CDH05 and CDH08 of the Barnet Local Plan (adopted March 2025) and the Adopted Residential Design Guidance SPD (2016).
- The proposed sub-division of the site and new unit would have a width so narrow as to be uncharacteristic and incongruous with the prevailing pattern of development, appearing as a cramped and contrived development that would ultimately be to the detriment of the character of the host site and fails to preserve the character and appearance of this part of the Watling Estate conservation area. This is contrary to Policies D3 and HC1 of the London Plan (2021), Policies CDH01 and CDH08 of the Barnet Local Plan (adopted March 2025) and the Adopted Residential Design Guidance SPD (2016).
- The proposed single storey rear extension by reason of its siting and excessive rearward projection will have an adverse impact on the visual and residential amenities of the neighbouring occupiers at No. 40 Orange Hill Road, including a harmful loss of sunlight, an overbearing appearance and loss of outlook, which would be to the detriment of the amenities of the occupants of the neighbouring property, contrary to Policies CDH01 and CDH05 of the Barnet Local Plan (adopted March 2025) and the Adopted Residential Design Guidance SPD (2016).
- The proposed development fails to meet the minimum floorspace standard and bedroom size for the dwelling. It would therefore fail to provide satisfactory living conditions for future occupiers, contrary to Policy D6 of the London Plan (2021), Policy CDH01 of the Barnet Local Plan (adopted March 2025), the Adopted Residential Design Guidance and Sustainable Design and Construction SPDs (2016) .
From the council's decision notice.
