Why it was refused

  1. The proposed ground floor rear extension by reason of its excessive depth and height would have an unduly detrimental impact to the residential amenities of the neighbouring property at No.19 Douglas Ave through its overbearing nature, resulting loss of outlook at ground floor and an increased sense of enclosure to the rear. This is contrary to policy DMP1 of Brent's Local Plan 2019-2041 and Brent's Residential Extensions and Alterations SPD 2025.

From the council's decision notice.
