LOCAL PLANNING / Bromley
Bromley’s permitted-development page lists several different Article 4 categories, including upwards extensions and particular alterations to dwellinghouse roofs. A property can therefore need a closer roof-rights check even when the initial question is simply whether a dormer will fit. Follow the council’s location map to the relevant direction, then compare its schedule with the exact works proposed.
Heritage guidance also changes over time. Bromley’s conservation-area page records new appraisals and management plans adopted in June 2025 for Shortlands Village, Bromley Town Centre, The Covert, The Thrifts and Chislehurst Road. If the property lies in one of these areas, use the adopted document alongside the current boundary, rather than relying on an older description included in a previous application.
For a loft or roof extension, we recommend recording the existing ridge, hips, chimneys and neighbouring roof forms before drawing the enlarged accommodation. Include views from any side road on a corner site. For a rear addition, establish how the original house relates to later garages, conservatories and garden buildings, so that the proposal can be assessed as a coherent whole.
Bromley says it cannot informally confirm whether a proposal falls within permitted development and points applicants seeking a formal decision towards a certificate of lawfulness. Allow for that evidence route when organising the project. The council’s Article 4 lists are not a blanket ban on alterations: they identify where an application is required, after which design and policy considerations still need to be addressed.
Householder decisions: eight-week national target after validation, with longer times possible.

Bromley: permitted development and Article 4 Directions · Bromley: conservation areas · GOV.UK: determining a planning application
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.
Bromley is London’s largest borough by area and contains extensive Green Belt and open land. Even modest proposals can need careful landscape, character and ecology consideration. The planning authority received 2,467 applications in the latest annual reporting period and issued 2,164 decisions. Of those decisions, 1,664 were granted and 500 were refused, equivalent to an authority-wide refusal rate of 23.1%. 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 Bromley contains conservation areas including Bromley Town Centre, Chislehurst, Shortlands Village, Petts Wood, Farnborough Village and Orpington Priory. 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.
Bromley has additional controls in parts of the borough and conservation-area designation restricts some works. The council’s appraisal for the relevant area should inform the design from the outset.
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 detached and semi-detached houses, historic villages, Victorian centres, garden-suburb streets, Green Belt-edge homes and commercial town centres. Recurring planning considerations include Green Belt, mature landscape, suburban spaciousness, side gaps, roof form, trees, heritage villages, parking and development on sloping 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.
