Why it was refused

  1. The proposed single storey rear extension, by reason of its height, depth and proximity to the neighbouring boundary would compromise the residential amenity of the occupants of the neighbouring property and rear garden at No. 37 Hillside, by reason of reduced outlook, loss of light, overbearing character and increased sense of enclosure, contrary to DMP1 of the Brent’s Local Plan (2019-2041) and Brent’s Residential Extensions & Alterations SPD (2025).
  2. The proposed detached outbuilding, by virtue of its layout incorporating kitchen facilities, a bedroom and a shower-room, together with the ability to be accessed independently from the public highway, would not be incidental to the use of the main dwellinghouse. The resulting nature and intensity of use would be out of keeping with the character of domestic rear gardens in the locality and would result in a substandard form of self contained residential accomodation. The proposal is therefore contrary to Policies DMP1 and BH12 of the Brent Local Plan (2019–2041) and the guidance contained within Brent’s Residential Extensions & Alterations SPD (2025).

From the council's decision notice.
