Why it was refused

  1. Having regard to the inaccurate and inconsistent plans submitted, the Local Planning Authority is unable to make a full assessment on this application. This is contrary to policy DMP1 of Brent's Local Plan 2019-2041.
  2. The proposed ground floor rear extension by reason of its excessive depth and height would fail to form an acceptable relationship with the main dwelling in its rear garden setting. This is contrary to policy DMP1 of Brent's Local Plan 2019-2041 and Brent's Residential Extensions and Alterations SPD 2025.
  3. The proposed ground floor rear extension by reason of its excessive depth and height would have an unduly detrimental impact to the amenities of the neighbour at No.39 Grove Crescent through an overbearing nature and an increased sense of enclosure. This is contrary to policy DMP1 of Brent's Local Plan 2019-2041 and Brent's Residential Extensions and Alterations SPD 2025.
  4. The proposed outbuilding by reason of its excessive height would have an unduly detrimental impact to the amenities of the neighbour at No.35 Grove Crescent by means of an overbearing nature.

From the council's decision notice.
