Why it was refused

  1. The proposed roof alterations, by reason of their scale, bulk and design, including the reconfiguration to a crown roof form at the hight of the existing min ridgeline, would result in an overly bulky and dominant appearance that fails to respect the articulated character of the existing dwelling. The development would lack subservience and erode the architectural interest of the host property. Furthermore, insufficient information has been provided regarding the use of the roof space. The proposal is therefore contrary to Brent's Residential Extensions and Alterations Supplementary Planning Document (2025) and Policy DMP1 of the Brent Local Plan, resulting in harm to the character and appearance of the property and the surrounding area.
  2. The site lies within a Local Site of Archaeological Interest Tier II and an Archaeological Priority Area. In the absence of a supporting archaeological statement, insufficient information has been provided to demonstrate that the proposed development would preserve or not harm archaeological remains. The proposal is therefore contrary to Policy DMP1 of the Brent Local Plan and the council's validation requirements, as it fails to provide sufficient information to enable a full assessment of its impact on heritage assets.

From the council's decision notice.
