Why it was refused

  1. The proposed extension of the mezzanine floor over the loading bay and the reduction in height of the vehicular access would result in the loss of an adequate on-site servicing area capable of accommodating 8metre rigid service vehicles. The development would therefore fail to provide safe and effective servicing arrangements and would necessitate servicing activity within circulation areas, to the detriment of pedestrian and vehicular safety and the efficient operation of the private estate. The proposal is consequently unacceptable and contrary to Policy BT3 of the Brent Local Plan (2019–2041).

From the council's decision notice.
