Brent's guidance for extensions, basements and shared houses
The development plan is the Brent Local Plan 2019-2041, adopted in 2,022. Brent publishes several documents that decide householder work: the Residential Extensions and Alterations Supplementary Planning Document, the Brent Design Guide Supplementary Planning Document (SPD1), the Basement Supplementary Planning Document and the Houses in Multiple Occupation SPD.
The basement document applies to a dig under a house or garden. See our basement impact assessment page for how that report fits with the planning route.
We open the extensions guidance first for any rear, side or roof proposal and build the sheets to its tests.

Article 4 directions, conservation areas and trees in Brent
With 39 Article 4 directions, Brent can remove permitted development for front elevations, boundaries or roofs in the areas each direction covers, and those areas are not always obvious from the street. Whether yours is covered is the first thing we check.
The borough has 23 conservation areas and 1,229 tree preservation orders. The council's data records no green-belt share, so we check the plot against the local plan rather than assuming proportion tests apply.
Historic England lists 93 entries: 1 at Grade I, 8 at Grade II* and 83 at Grade II. There are also 11 entries on the Heritage at Risk Register.
Flats, houses and tenure
Only 43.3 per cent of Brent households live in a house, and 38.4 per cent are owner-occupied. Permitted development rights for householders never extend to flats, so a flat owner here needs a full application, and usually a freeholder's consent too.
For houses, a terraced home sold for £700,019 on average in the latest Land Registry figures, and a semi-detached one for £829,853.
The average price moved by -2.6 per cent in the latest twelve months, so the economics of building up or out are worth checking against a current valuation.
How Brent decides applications
In the latest twelve months of published figures Brent decided 879 householder applications and granted 86.6 per cent. Of those, 97.2 per cent were decided within eight weeks or an agreed extension.
Prior approval for larger home extensions is a harder route here: 10 granted against 79 refused in the latest national statistics. Past figures do not predict your decision, but they help us choose between routes.
The council also dealt with 348 lawful development certificate applications in that period, so a certificate is a well-used route.
The national statistics series counts 924 householder decisions in its latest year, with 85.5 per cent granted.
Levies to plan for
Brent is in band 2 of the Mayor of London's levy at £72.73 per square metre for permissions granted this year, and it charges its own levy under the Brent CIL Charging Schedule.
We list any liability in the next-steps pack so the figure is never a surprise.
Minor schemes, conversions and shared homes
Brent decided 734 minor applications, such as a small conversion or a new dwelling, and granted 74.8 per cent of them, with 95.2 per cent decided in time. For a flat conversion or a small infill scheme these are the more relevant figures.
Shared houses are controlled locally: the council publishes its own guidance for them, and where its Article 4 direction applies, turning a family house into a small shared house needs planning permission. We check that before any layout is drawn.
Domestic gardens cover about 30.3 per cent of the borough, and there are 4 registered parks and gardens, so overlooking, trees and setting count on some sites.
A detached home here sold for £1,326,037 on average and a flat for £378,992, in a borough of 118,612 households. We draw to the guidance whichever route the owner chooses.
What we check on a Brent address before any design
We open the council's Article 4 map first, because it settles whether your front, roof or boundary needs consent. Then we look at conservation status, listed neighbours, protected trees and the planning history of the house and the terrace.
If the house is a flat or part of a converted building, we ask for the lease, since consent from the freeholder is separate from the council's. For a house, we measure the original rear wall and the neighbours' windows, then set extension depth against the council's tests.
You receive a fixed quote and a clear route. An independent technologist checks the final sheets before they are submitted, and we answer the officer's questions afterwards.

Questions
Do I need planning permission for a loft conversion in Brent?
Often, because the borough's 39 Article 4 directions and 23 conservation areas withdraw rights, and flats have none. We check your address for free first.

Householder planning drawings start at £745 including VAT, fixed and published up front. The council fee is paid to the council.
Does Brent have guidance on basements?
Yes, the Basement Supplementary Planning Document. We read it alongside the extensions guidance when a scheme goes below ground.
Which guidance covers home extensions in Brent?
The Residential Extensions and Alterations Supplementary Planning Document and the Brent Design Guide Supplementary Planning Document (SPD1), read with the local plan.
