Why it was refused

  1. The proposed first floor parapet, by reason of its design, proportions, prominence and relationship with the hipped roof form of the host dwelling, would appear as an incongruous and discordant addition, resulting in an unsympathetic roof form that would be harmful to the character and appearance of the host dwelling and surrounding streetscene. The proposal is therefore contrary to Policies DMP1 and BD1 of the Brent Local Plan (2019-2041).
  2. The submitted drawings, by reason of their inconsistencies and inaccuracies, fails to provide an accurate representation of the development for which planning permission is sought, preventing a full and proper assessment of the proposal. The proposal is therefore contrary to Policy DMP1 of the Brent Local Plan (2019-2041).

From the council's decision notice.
