Bromley (BR1) runs from the pedestrianised Market Square and High Street of the town centre out to the large detached villas of Bickley, mixing a busy commercial core with leafy Edwardian avenues. Rear extensions and loft conversions on the villa streets are the mainstay of our work here.

The Bromley Town Centre conservation area, designated in 1985, controls the historic Market Square end of the High Street, while the Sundridge Avenue and Mavelstone Road conservation areas towards Bickley protect wide-plot villas and their garden settings. We check a BR1 address against these before drawing to Bromley's residential guidance.

Planning in Bromley (BR1): what to know before you apply

BR1 carries no householder Article 4 direction — the borough's one such direction sits over the Chancery Lane conservation area in Beckenham (BR3) — so many Bromley houses keep permitted development rights for rear and loft work. But the Bromley Town Centre, Sundridge Avenue and Mavelstone Road conservation areas tighten control over frontages, rooflines and materials, and work to the large Bickley villas draws close design scrutiny, so we confirm the conservation-area position on the council's map first.

Typical Bromley housing stock

Large detached and semi-detached Edwardian villas on the leafy Bickley avenues, tighter Victorian terraces nearer the station, and the mixed commercial fabric around the pedestrianised Market Square and High Street of the town centre.

Planning Drawings for Bromley (BR1) homes: the package and the process

Every planning drawings we prepare for an Bromley property is drawn to London Borough of Bromley’s validation standards and tuned to the BR1 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Planning drawings are the scale drawings a London council uses to judge your application: existing and proposed floor plans, elevations, sections and site plans that show the design, scale and neighbour impact of your project. DrawingsDirect produces complete, validation-ready planning drawing sets for extensions, lofts and conversions across London.

What is included in a planning drawing set?

A council will only validate an application that contains the right drawings at the right scale. Our standard planning set covers everything a London validation team expects.

  • Site location plan (1:1250) and block plan (1:500)
  • Existing floor plans, elevations and sections
  • Proposed floor plans, elevations and sections
  • Roof plans where relevant, with heights and materials annotated
  • A design and access or heritage statement where the borough requires one

How are planning drawings different from building regulations drawings?

Planning drawings show what the building will look like and how it sits in its context. Building regulations drawings show how it will be built safely — structure, insulation, fire escape and drainage. Most projects need both; our Complete package covers the two together with structural calculations coordinated in-house.

FAQ

Planning Drawings in Bromley BR1 — FAQs

What scale should London planning drawings be?+
Site location plans are 1:1250, block plans 1:500, and floor plans, elevations and sections are typically 1:100 or 1:50. We format every drawing to your specific borough's requirements.
Do I need an architect to produce planning drawings?+
No. MCIAT-chartered architectural technologists produce the same council-accepted planning drawings with the same professional accountability, and councils assess the drawings, not the author's job title.
How many revisions are included in the fee?+
All of them. The fee is fixed and we redraw free until your council approves — revisions requested by a planning officer never cost you extra.
Can you draw from my existing plans?+
We can work from existing measured drawings, but for accuracy we usually carry out a laser survey so the proposed set matches your property exactly.
Do planning drawings guarantee approval?+
No drawing can guarantee a decision, but drawing to the local plan and validation checklist maximises your odds — and we redraw free until approval.
Do I need planning permission for an extension in Bromley?+
Bromley has no borough-wide Article 4 direction affecting typical householder permitted development, so its detached and semi-detached homes often keep fuller rights than inner-London terraces — larger rear and single-storey extensions can qualify. The binding constraints are green-belt policy on outer properties and conservation control in Chislehurst, Keston and Bromley Town. We check both and can confirm permitted development with a Lawful Development Certificate.
Can I build a bigger extension because Bromley plots are larger?+
Often, yes. Bromley's generous interwar plots make substantial rear and double-storey extensions viable where an inner-London terrace could not accommodate them. The limit is usually policy rather than space — green belt restricts scale on outer properties, and conservation areas control design. We design to use the plot fully within those limits, checking permitted-development allowances for detached homes first.
How does green-belt designation affect my Bromley project?+
On green-belt properties toward Orpington, Chislehurst and the borough's edges, extensions are assessed against strict limits on disproportionate additions to the original dwelling. It does not rule out an extension, but scale and siting matter and the case must be evidenced carefully. We confirm whether your property is green belt and design a scheme that stays within policy.
How long does Bromley Council take to decide?+
Bromley determines most householder applications within the statutory eight-week period once validated. As London's largest borough by area, its casework spans suburban semis to green-belt properties, so a complete, correctly scaled submission is the best way to avoid a validation query and keep to that timescale.
How much do planning drawings cost in Bromley?+
We quote a fixed fee upfront, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Bromley approves. Because plots here allow larger schemes, the fee tracks the project's complexity — a single-storey rear differs from a double-storey or a green-belt case — and we confirm it once we understand your plans.
