Why it was refused

  1. The proposed first-floor rear extension, when considered cumulatively with previously approved extensions, would create an overly dominant form of development that fails to remain subordinate to the original dwelling. It would erode the architectural character and legibility of the host dwelling and fail to preserve the character and appearance of the Sudbury Court Conservation Area, contrary to Policies DMP1 and BHC1 of the Brent Local Plan and the Sudbury Court Conservation Area Design Guide (2015).
  2. The proposed first-floor rear extension would result in less than substantial harm to the significance of the Sudbury Court Conservation Area, a designated heritage asset. The identified harm would not be outweighed by public benefits and the proposal therefore conflicts with Policy BHC1 of the Brent Local Plan.

From the council's decision notice.
