Penge consent route

Do I need loft conversion drawings in Penge?

No Article 4 Direction covers Bromley, which keeps the Penge permitted-development route open on unlisted houses. Penge is Victorian and Edwardian terraces; near Penge East station that context does most of the work in an officer report. Of the 48 conservation areas Bromley designates, Beckenham and Keston are the ones that most often change how a Penge project is routed. A Penge address on the edge of the boundary is checked, not guessed.

Every SE20 job starts with checking Article 4 directions street by street. Everything on a Penge scheme is measured from the victorian and edwardian terraces outward. The borough policy layer over every SE20 address is set out on Bromley planning. The Penge survey then carries into house extension drawings in Penge if the project runs on to construction.

Bromley Council timescales

How long does Bromley Council take to decide?

A Penge application is not live until London Borough of Bromley validates it, which takes one to two weeks on a complete pack. Survey first: we measure the Penge property in person, then draw the existing plans, sections and elevations from that data.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

Expect a site visit to the Penge property during the consultation period. A Penge pack that misses a scale bar is a pack London Borough of Bromley will reject — ours do not.

Most Penge refusals trace back to overlooking, not to size. We photograph the Penge property alongside the measurements for the record.

The party wall step is not optional on shared Penge walls, and serving late is what stalls sites. Once consent is granted, architectural drawings follows for the SE20 property.

Bromley stock

What Penge's housing stock means for your plans

Penge is characterised by victorian and edwardian terraces, concentrated across SE20 in the Anerley / Penge area. Penge is not uniform, but the victorian and edwardian terraces recurs often enough across SE20 that the structural pattern is predictable once measured. For Penge owners this matters because the Victorian butterfly and double-pitched roofs on these streets normally clear the 2.2 m head height a dormer conversion needs once the ceiling joists are raised. On Bromley stock it changes the party wall position. Bromley Council reads a Penge elevation against its neighbours first.

A Penge basement stands on its drainage and party wall evidence. If the SE20 job later needs planning permission for SE20 properties or building regulations drawings, the existing drawings already carry the measurements.

Who signs the drawings

MCIAT chartered technologists working across Bromley

MCIAT charter sits behind every Penge submission we make, and the same person who surveys the property signs the drawings off. Not every Penge scheme is clear-cut. Where Beckenham or the Penge East station setting is in play, Bromley Council pre-application advice comes before the SE20 submission.

Drawings are produced by chartered members of the Chartered Institute of Architectural Technologists (MCIAT), the professional body for technical design and building-regulations competence. First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations. Confirm your local authority at gov.uk and submission requirements on the Planning Portal. Studio: 71–75 Shelton Street, London WC2H 9JQ.
