Why Brent refuses single-storey rear 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…”
32A Park Road, Wembley, HA0 4AT
“1 The proposed extension, by virtue of its excessive depth and eaves height, would have an unduly detrimental impact on the outlook, light and result in an increased sense of enclosure to the habitable room windows and the rear patio enjoyed by the neighbouring occupier(s) at No 30 and 34a & 34b Park Road. This is contrary to policy DMP1 of the Brent Local Plan 2019-2041 and the guidance in Brent's Residential Extensions and Alterations SPD 2025. 2 The proposed outbuilding by virtue of its excessive footprint would represent an overdevelopment of the rear garden and result in the retention of…”

“1 The proposed rear extension would facilitate a revised internal layout resulting in the provision of an additional bedroom with no outlook and insufficient information to demonstrate that an acceptable level of daylight would be achieved. The proposal would therefore result in a poor and unacceptable standard of accommodation for future occupiers, contrary to Brent Residential Extensions and Alterations SPD (2025), Brent Local Plan (2019-2041) policy DMP1 and London Plan policy D6. 2 The proposed front porch, due to its combined excessive depth, finish and proposed front doors, would result…”

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 single-storey rear 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 The approval figure counts approved and refused planning applications only: withdrawn and undecided ones, lawful development certificates and prior approvals are left out.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.
