LOCAL PLANNING / Brent
Brent states that all its residential conservation areas are covered by Article 4 directions. That makes checking the relevant direction an early task for apparently minor improvements as well as larger extensions. Read which works and properties are included: a restriction on front windows, for example, should not be treated as a universal prohibition on every alteration to the house.
The council’s conservation-area directory provides maps, appraisals and, where available, design guides. Its interactive policies map can be searched by address. Barn Hill, Mapesbury and Kensal Green each have their own records, while Kensal Rise also has a separate designation and appraisal. Use the entry for the actual property rather than choosing a guide simply because the architectural style looks similar.
One easily missed local example is Manor Close. Brent explains that an Article 4 direction controlling front-garden vehicle hardstanding remains in effect even though the area ceased to be a conservation area in 2004. A conservation-map search alone is therefore insufficient when planning parking works. Confirm the direction’s boundary and the proposed surfacing and access arrangements before treating a driveway as a straightforward landscaping job.
For a home improvement brief, record the original windows, roof covering, front boundary and garden layout before deciding what to replace. Prepare elevations that distinguish repairs from new work and identify proposed materials clearly. If the scheme combines a loft, extension and front-garden changes, review all three together; leaving the apparently smaller items off the planning drawings can leave an important consent question unresolved.
Householder decisions: eight-week national target after validation, with longer times possible.

Fees are starting prices and depend on property size, complexity, location and scope. Statutory application charges, Planning Portal charges, Building Control fees, specialist consultants and VAT where applicable are additional.
These are authority-wide figures for the year ending 31 March 2026. Applications received and decisions issued are separate flows: a decision in the period may relate to an application received earlier. The official return combines several planning application routes and does not provide a reliable borough total limited only to full applications.
The borough contains both fine-grained residential streets and some of London’s largest regeneration areas. Development density, amenity and servicing need to be addressed at the correct scale. The planning authority received 2,122 applications in the latest annual reporting period and issued 1,963 decisions. Of those decisions, 1,532 were granted and 431 were refused, equivalent to an authority-wide refusal rate of 22.0%. These totals provide useful context but do not predict the outcome of a specific property or proposal.
Approval depends on the site, planning history, Local Plan policies, the London Plan, permitted-development position, design quality, neighbour effects, heritage and environmental constraints. We review those matters before fixing the application strategy.
We aim to make the process effortless for the client. After submission we check whether the application has been validated, monitor the council register and key dates, and remain available to provide information that is reasonably required. Where the case officer identifies a specific concern and is willing to consider an amendment, we assess it quickly and coordinate an appropriate response rather than allowing avoidable delay.
London Borough of Brent contains conservation areas including Queen’s Park, Mapesbury, Barn Hill, Kensal Green, Sudbury Court and Northwick Circle. A conservation area does not prevent thoughtful change, but the council must give special attention to preserving or enhancing its character and appearance. This commonly affects roof alterations, dormers, front elevations, windows and doors, boundary walls, hardstanding, demolition, plant, materials, trees and development visible from public viewpoints.
Brent applies Article 4 controls in residential conservation areas. Alterations that might normally be permitted development can require planning permission, so the applicable direction must be checked.
For a property in or near a conservation area we review the relevant appraisal and management guidance, identify features that contribute to significance and explain how the proposed design responds. A heritage statement, schedule of materials, detailed joinery information, streetscape drawings or verified views may be needed depending on the project.
The borough includes Victorian terraces, inter-war suburban houses, mansion flats, estates, high-street premises and major regeneration sites around Wembley and the growth areas. Recurring planning considerations include intensification, HMOs, roof additions, privacy, amenity space, parking, servicing and the relationship between domestic-scale streets and larger development sites. The correct solution is therefore site-specific: a form of development that is acceptable on one street may be unsuitable on another because of plot pattern, designation, visibility, neighbour relationships or planning history.
We coordinate the architectural work with other disciplines where the planning authority or project requires them. This avoids fragmented information and gives the client one coordinated route through the process.
The principal statutory planning application fees are set nationally rather than by each London borough. From 1 April 2026, a typical householder application to alter or extend one house costs £548. Other development types use different calculations. Planning Portal service charges, council pre-application advice, Building Control, specialist reports and professional fees are separate.
Horizon Architecture charges £100 for planning application submission, with planning drawings starting from £1,400. We confirm the architectural scope, likely statutory fee and foreseeable specialist inputs before appointment.
We are expanding the neighbourhood guides within this borough. The borough page remains the central reference for authority-wide statistics, conservation guidance and our planning service.
No architect can guarantee a council decision. We improve the prospects through planning-history checks, policy analysis, proportionate design, complete documentation and active management after submission.
Yes. We monitor validation and determination, check the public record, remain available to the case officer, supply reasonable clarifications and respond quickly where a focused amendment could assist the application.
No. The official authority-wide applications-received series combines several planning routes. It does not publish a reliable annual borough total limited only to full applications, so we state the limitation rather than inventing a number.
From 1 April 2026, the nationally set statutory fee for alteration or extension of one house is £548. Planning Portal charges, council pre-application services and professional fees are separate.
Yes, subject to the agreed scope. We can coordinate structural engineering, heritage, acoustic, arboricultural, drainage, flood-risk, transport, daylight, fire, energy and building-services information.
Not automatically. The design must preserve or enhance the area’s character and respond to the appraisal, visibility, roof form, materials, historic fabric, trees and any Article 4 Direction.
