From Chislehurst to Beckenham, we prepare planning drawings Bromley Council can approve — measured, policy-checked and submitted for you, with free revisions until you have a decision.
Bromley is London's largest borough by area, and much of it feels more Kent than capital: interwar semis with deep gardens in Petts Wood and West Wickham, substantial detached homes around Chislehurst and Keston, Victorian villas in Beckenham and Shortlands, and green-belt fringes to the south. Bromley Council's planners are correspondingly protective of suburban character — spacious plots, consistent building lines and generous gaps between houses are exactly what its residential design policies exist to defend.
That shapes how we draw. A wraparound extension that would be routine in inner London needs careful handling in Bromley if it closes the gap to a boundary or breaks the rhythm of a detached frontage. Side extensions are the classic flashpoint: officers look hard at set-backs from the front elevation and set-downs from the ridge so a pair of extended houses never reads as a terrace. We build those moves into the proposed elevations from the start, rather than negotiating them after an objection.
Every pack is prepared by chartered designers, checked against Bromley's validation requirements, and — because we track live decision data for the borough — priced against a realistic view of your approval odds before you commit.
The widget below shows Bromley's actual decision record, drawn from official planning statistics rather than marketing claims. Approval odds in the borough are strongly linked to drawing quality: schemes that demonstrate respect for plot spacing, garden depth and roofline on properly scaled elevations are decided faster and refused less. That is precisely what a professional pack buys you — the objections answered before the case officer has to raise them.

Many Bromley projects do not need planning permission — single-storey rear extensions, most loft conversions and garden outbuildings can proceed under permitted development within national limits. You will usually need a full application to Bromley Council if any of these apply:
Bromley's case officers think in gaps, gardens and rooflines. Our elevations show set-backs, set-downs and boundary distances explicitly — so the scheme reads as an approval, not an argument.

The borough's dominant stock is interwar — street after street of 1930s semis and chalet bungalows in Petts Wood, Orpington, West Wickham and Hayes. Their hipped roofs make hip-to-gable loft conversions with rear dormers the single most common project we draw in Bromley, usually paired with a dormer set below the ridge and clad to match the existing tiles. Where the pair's symmetry matters to the street, we detail the gable carefully; where a neighbour has already converted, we match the precedent.
Victorian and Edwardian Beckenham, Bromley town and Shortlands bring a different workload: rear and side-return kitchen extensions, cellar conversions and loft rooms in steeper roofs. And across the borough's larger plots — Chislehurst, Bickley, Keston — we draw substantial two-storey extensions, garden rooms and annexes where the questions are massing, trees and, on the fringes, green-belt policy.
In each case the drawing pack is tuned to what Bromley's validation team requires: existing and proposed plans and elevations at 1:100 or 1:50, a location plan at 1:1250, a block plan showing boundaries and neighbouring buildings, and — in conservation areas — a heritage statement that takes the designation seriously rather than boilerplating it.
Bromley's garden-suburb DNA also shapes what happens after submission. Neighbour consultation carries real weight on quiet residential roads, and the objections that stick are the predictable ones: overshadowing across a shared boundary, a side extension that closes a gap, an outbuilding that looms over a fence line. We anticipate all three by dimensioning boundary distances and showing neighbouring properties on the proposed elevations — so the case officer can dismiss objections with the drawings in front of them, rather than asking you for amendments mid-application.
And because every pack starts from a measured survey, the step to building regulations drawings and structural calculations after approval is seamless: what Bromley approved is exactly what your builder prices, with no redrawing and no discrepancies for building control to query.
The signature 1930s-semi project — gable build-up, rear dormer and stair over the existing flight, drawn with the roofline details Bromley officers expect.
Kitchen-diners across the back of semis and detached homes, with boundary distances and neighbour daylight tested on the elevations.
Set back from the front, set down from the ridge — composed so extended pairs never read as a terrace, the borough's classic refusal reason.
Home offices and studios under permitted development where possible, with height and coverage checked against the rules before you build.
Chislehurst, Keston Park and the borough's rural south need heritage and openness arguments made properly — we prepare the statements alongside the drawings.
Once permission lands, we produce the building regulation drawings and coordinate structural calculations so your builder can price accurately.
Bromley Council decides householder applications for Bromley, and its recent record and the permitted-development limits that apply here set out below give Bromley homeowners a realistic starting point before any drawing begins.
| Measure | Figure for Bromley |
|---|---|
| Bromley Council householder approval rate | 83% |
| England-wide householder benchmark | 87% |
| Loft dormer permitted-development limit (Class B) | 40m³ terrace / 50m³ semi or detached |
| Single-storey rear extension depth (Class A) | 3m terrace / 4m detached |
| Dominant housing era | Victorian (1837–1901), Edwardian (1901–1910), interwar (1918–1939) and postwar (1945–1970) |
| Statutory decision period | 8 weeks |
| Conservation / Article 4 status | Article 4 direction in force; PD removed in Bromley Town, Chislehurst and Beckenham |
Bromley runs 4 points below the national average. Approval rate: MHCLG householder planning statistics for Bromley Council; permitted-development limits: GPDO 2015, Schedule 2, Part 1 (Classes A–B).
The statutory determination period is eight weeks from validation, and most householder applications in Bromley are decided within it. Applications in conservation areas or the green belt can take longer if consultees are involved. We track progress and answer case-officer queries promptly to keep your application moving.
Possibly — Bromley has numerous conservation areas, including Chislehurst and Keston Park, and several carry Article 4 directions restricting permitted development. We check your address against the council's designations as part of the free approval check, before any drawing work starts, so there are no surprises at validation.
Usually yes, within limits. Green-belt policy allows extensions that are not disproportionate to the original house, so the drawings must demonstrate scale against the dwelling as first built. We prepare volume comparisons and clear elevations that make the proportionality case explicitly for the officer.
Most Bromley lofts proceed under permitted development — hip-to-gable and rear-dormer conversions within the volume allowance rarely need an application. Conservation areas, flats and houses with PD rights removed are the exceptions. We confirm your route first and, where PD applies, recommend a lawful development certificate for certainty.
Existing and proposed floor plans and elevations at 1:100 or 1:50, a site location plan at 1:1250 with the site edged red, and a block plan at 1:500. Roof works add a roof plan and section, and conservation-area schemes need a heritage statement. Our packs cover the full validation checklist.
We revise and resubmit free of charge. Bromley refusals typically cite bulk, loss of gaps between houses or garden amenity — all fixable with targeted amendments to set-backs, projections or roof form. A resubmission within twelve months of refusal usually attracts no further council application fee.
