Why it was refused

  1. The proposed single-storey rear extension, by reason of its excessive height along the shared boundaries, substantial depth and siting, would result in an unduly dominant and overbearing form of development which would cause an unacceptable loss of outlook, increased sense of enclosure and loss of light to the neighbouring occupiers at No. 30 Valley Drive. The proposal would therefore be detrimental to the living conditions of adjoining occupiers and would be contrary to Policy DMP1 of the Brent Local Plan (2019-2041) and the guidance contained within Brent's Residential Extensions and Alterations SPD (2025).
  2. The proposed first-floor rear extension, by reason of its excessive depth, would result in a visually prominent and incongruous form of development that would fail to appear subordinate to the host dwelling. The proposal would harm the character and appearance of the host property and would be out of keeping with the prevailing pattern of development within the surrounding area. The proposed development would therefore be contrary to Policies DMP1 and BD1 of the Brent Local Plan (2019-2041) and the guidance contained within Brent's Residential Extensions and Alterations SPD (2025).
  3. The submitted existing and proposed drawings are inaccurate, inconsistent and not to scale, such that they fail to adequately and reliably depict the existing dwellinghouse and the development proposed. As a result, the Local Planning Authority is unable to fully assess the scale, form and impact of the proposed development on the host property, neighbouring properties and the surrounding area. The submission of accurate plans is fundamental to the proper consideration and determination of planning applications. The proposal therefore fails to provide sufficient information to enable a full assessment of its acceptability and is contrary to Policy DMP1 of the Brent Local Plan (2019-2041).
