Why Brent refuses two-storey and first-floor extensions
The council's own words, quoted from recent decision notices.
24, Ealing Road, Wembley, HA0 4TL
“1 The proposed development would involve the installation of a replacement extraction flue and associated plant to serve the extended restaurant use. However, insufficient information has been submitted regarding the location, specification and acoustic performance of the proposed extraction equipment, and a Noise Impact Assessment has not been provided. As a result, the Local Planning Authority cannot be satisfied that the development would not give rise to unacceptable noise and vibration impacts to nearby residential occupiers, particularly those within adjoining residential properties. Th…”

“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 th…”

“1 The proposed two-storey side and rear extension, by reason of its excessive ridge height and crown roof, 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 Al…”

How these figures are made
Planning applications London Borough of Brent received Oct 2021 to Oct 2026, from the council's public planning register as collected by Planning Signal. An application counts as a two-storey extension when its own description says so (rules-based classification, tested against blind labelled samples). Duplicate records of one application are counted once. The approval figure counts approved and refused planning applications only: withdrawn and undecided ones, lawful development certificates and prior approvals are left out. Decision times use the received (or validated) date and the decision date the council published.
Past decisions describe what happened to other applications. They are not a prediction for yours: every application is decided on its own design and the council's current policies.
