Why it was refused

  1. The proposed first-floor extension with a hipped roof, would result in a discordant feature that detracts from the character of the dwellinghouse and wider locality, contrary to DMP1 & BD1 of Brent’s Local Plan (2019-2041) and Brent’s Residential Extensions & Alterations SPD (2025).

From the council's decision notice.
