Building Regulations Drawings · SE25 South Norwood
Croydon applies householder control across SE25, with conservation pockets around Woodside Green; one of London's most affordable period markets.
This page covers one part of the borough. For the full picture — fees, timelines and the council's current position — read building regulations drawings in Croydon.
Building regulations drawings for a South Norwood project turn the design into a construction-ready set — Part A structure, Part B fire, Part L thermal, Part M access — for Croydon Council Building Control or an approved inspector. On SE25's victorian and edwardian terraces and bay-fronted semis, the recurring details are steel beams over knocked-through ground floors, loft floor build-ups, and insulation upgrades to solid period walls around South Norwood, Selhurst, Woodside, Norwood Junction.
A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
Across South Norwood, Selhurst, Woodside, Norwood Junction in SE25, the dominant property is victorian and edwardian terraces and bay-fronted semis around south norwood and selhurst, with post-war estates near the centre. That stock shapes what building regulations drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Croydon Council judges each on design quality and neighbour impact. We survey the specific South Norwood property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SE25 streetscape.

Yes. The Victorian and Edwardian terraces and bay-fronted semis around Portland Road and South Norwood Hill suit side-return, rear and loft extensions, much of it within Permitted Development outside the conservation areas, confirmed with a Lawful Development Certificate. We confirm the route and draw to Croydon's checklist.
Usually yes — a rear dormer or hip-to-gable on the semis, within the volume allowance and confirmed by a Lawful Development Certificate, provided you're not in the Woodside Green conservation area. We check the constraints for your road and draw it for Building Control.
Family-house extensions and lofts on the Victorian and Edwardian terraces and semis around Selhurst and Woodside — side-returns, rear additions and dormers as families grow. With houses around £450,000-£700,000, SE25 offers strong value, and a council-ready scheme protects both approval and resale.
Croydon's wider regeneration and the tram and Overground links keep SE25 well-connected and improving, supporting values. For a house project the binding controls remain Permitted Development limits and the local conservation area, which we check for your address before quoting.
Croydon Council charges its own statutory application fee (currently £548 for a householder planning application, £610 for a full application). We quote the drawings as one fixed price and the free site survey covers every SE25 address.
For a SE25 project across South Norwood, Selhurst, Woodside, Norwood Junction, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Croydon Council (8 weeks for a householder application). We carry the South Norwood application through every officer query to the decision.
South Norwood (SE25) sits primarily in Croydon, so applications are decided by Croydon Council. Conservation areas within SE25 include South Norwood (Lower Norwood), Woodside Green, where full planning and a Heritage Statement are required. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind building regulations drawings in South Norwood — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Croydon Council Building Control or an approved inspector. On SE25's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on SE25 homes.
Planning history and precedent stop at the borough line, so the comparable approvals nearby may sit elsewhere. See all services in SE19, SE20 and SW16.
Pick a slot that suits you. No obligation and no sales pressure, just straight answers on your planning route.
Every SE25 postcode district we draw in, the stock that dominates it and the authority that validates a building regulations package there. SE25 fees below are the statutory England rates for 2026, not building regulations package estimates.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| SE25 | South Norwood / Selhurst | Victorian terraces | South Norwood / Selhurst sits inside SE25. The Building Regulations check can be bought from Croydon Council building control or from a private approved inspector — the owner chooses, and the choice is not tied to the borough boundary. |
| SE25 | South Norwood | Victorian terraces | A SE25 address in South Norwood can route building control through Croydon Council or through an approved inspector. Both discharge the same duty; the fee and the inspection timetable are what differ. |
| SE25 | Selhurst | Edwardian terraces | Selhurst is inside SE25. Building control is not a council monopoly: an approved inspector can take the same job, discharging the same duty under the Building Regulations, wherever the address sits. |
| SE19 | Upper Norwood / Crystal Palace | Victorian villas, Edwardian terraces | Adjoining district to SE25. Building control here can go to Croydon or to an approved inspector, on the same terms as in SE25. |
| CR0 | Croydon / Addiscombe / Shirley | Edwardian terraces, post-war flats | Adjoining district to SE25. Building control here can go to Croydon or to an approved inspector, on the same terms as in SE25. |
| CR2 | South Croydon | mixed stock | Adjoining district to SE25. Building control here can go to Croydon or to an approved inspector, on the same terms as in SE25. |
Roof pitch, wall build-up and plot depth change every few SE25 streets, and each one changes what a building regulations package can achieve at that address.
How designation changes a SE25 (South Norwood / Selhurst) building regulations package: Croydon Council maintains 24 conservation areas, including Crystal Palace, Old Coulsdon, Purley. Inside any of them a SE25 (South Norwood / Selhurst) building regulations package cannot rely on permitted development, and the route becomes a £548 householder application determined in 8 weeks rather than a £249 prior approval in 6 weeks. Purley sets the tone for SE25 (South Norwood / Selhurst) casework.
Article 4 and your SE25 (South Norwood / Selhurst) building regulations package: Croydon Council has made no borough-wide direction, so permitted development for a building regulations package in SE25 (South Norwood / Selhurst) generally survives outside SE25 (South Norwood / Selhurst) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a SE25 owner records that a building regulations package was lawful.
The building fabric around SE25 (South Norwood / Selhurst): Victorian villas in Upper Norwood and Crystal Palace; Edwardian terraces in Thornton Heath and Selhurst; 1930s semi-detached in Purley and Coulsdon; post-war in Croydon central. Large, mixed-density outer borough; permissive in outer areas; heritage controls in conservation pockets; major regeneration in central Croydon. A building regulations package in SE25 (South Norwood / Selhurst) is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Croydon Council.
