House Extension Drawings in Bromley |

No Article 4 Direction covers Bromley, which keeps the Bromley permitted-development route open on unlisted houses. In Bromley the streetscape argument usually decides the case before the numbers do, because the area is Victorian and Edwardian centre. Where a Bromley property sits inside Chislehurst or Beckenham — two of Bromley's 48 designations — permitted development narrows and a full Bromley Council submission is usually quicker. That check comes before anything else on a Bromley job.

How Article 4 directions apply to your Bromley street is settled at survey stage, not after submission. On a Bromley house the measurements bite through the victorian terraces: it sets the original rear wall, and the roofline around The Glades sets what ridge height will pass. The borough policy layer over every BR1, BR2 address is set out on Bromley planning. The Bromley survey then carries into loft conversion drawings in Bromley if the project runs on to construction.

An incomplete Bromley pack sits in the London Borough of Bromley validation queue. The first thing we do in Bromley is measure — every room, every level change.

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.

Most Bromley householder cases are decided under delegated powers, not committee. The BR1 pack is issued at 1:100 and 1:50 with a 1:1250 location plan.

London Borough of Bromley weighs material objections only — a Bromley neighbour disliking the design is not one. A Bromley survey takes two to three hours and needs access to every room.

Shared walls are the norm in Bromley; the notice period is not optional. Once consent is granted, architectural drawings follows for the BR1 property.

Bromley is characterised by victorian terraces, edwardian villas, post-war flats, concentrated across BR1, BR2 in the Bromley / Bickley area. How the victorian terraces in Bromley was built decides what can be opened up and where the load has to go. What that means for a BR1, BR2 address: the side-return infill is the classic move on these Victorian terraces — 3 m of permitted development depth plus the width of the original side passage. We resolve it before the Bromley design is fixed. A Bromley proposal that breaks the prevailing eaves line invites a refusal.

Subterranean work in Bromley has no dedicated borough policy behind it; the BR1 water table and the party walls are the real constraints. Survey data from the Bromley property flows straight into planning permission for BR1 properties or building regulations drawings without a second site visit.

What the Bromley drawing pack contains

For a BR1, BR2 address the deliverables are fixed, not open-ended.

• existing and proposed ground-floor plans for the Bromley property
• proposed rear elevation
• long section through the extension
• site and block plans
• party wall position drawing

Streets and landmarks we survey around Bromley

• Biggin Hill — shared flank walls, so Biggin Hill party structure notices go out before work starts.
• Lee Green — closet wings that change how a rear extension meets the Lee Green back addition.
• Sundridge Park — shared flank walls, so Sundridge Park party structure notices go out before work starts.
• Hayes Lane — side returns where the 45-degree amenity test decides how far a Hayes Lane extension goes.
• London Cannon Street — front-to-back level changes that drive the London Cannon Street section drawings.
• The Glades — it fixes the local datum a Bromley roof extension is judged against.
• Bromley High Street — it anchors the Bromley streetscape argument in an officer report.
• Hayes School — it fixes the local datum a Bromley roof extension is judged against.
• Bishop Justus School — nearby victorian terraces takes its scale from this frontage.
• Darrick Wood School — it anchors the Bromley streetscape argument in an officer report.
• British Academy — schemes in view of it attract closer officer scrutiny.
