Why it was refused

  1. The proposed outbuilding by virtue of its excessive footprint would represent an overdevelopment of the rear garden and result in the retention of an inadequate amount of usable private amenity space for the enjoyment of the existing occupants. This is contrary to policies DMP1 and BH13 of the Brent Local Plan 2019-2041 and the guidance in Brent's Residential Extensions and Alterations SPD 2025.
  2. The proposed outbuilding by virtue of its siting on a separate parcel of land, its indendent access and the inclusion of shower facility would fail to demonstrate that it would support a use that is incidental to the existing flat. This is contrary to policies DMP1 and BH12 of the Brent Local Plan 2019-2041 and the guidance in Brent's Residential Extensions and Alterations SPD 2025.
  3. In the absence of accurate plans showing the siting of the existing outbuilding in relation to the off-site tree at No.49 Rosebank Avenue, together with the location of the proposed development and details of the proposed foundations, the application has failed to demonstrate that the proposed development would not result in any greater encroachment into the tree's root protection area than the existing arrangement. This is contrary to policies DMP1 and BGI2 of the Brent Local Plan 2019-2041.
