Structural Calculations · SE22 East Dulwich
SE22 is decided by Southwark Council. East Dulwich is one of London's strongest family-extension markets — rows of Victorian and Edwardian bay-fronted terraces ideal for side-return and rear extensions and loft dormers, mostly outside conservation areas, though the Dulwich fringe and Estate land carry tighter controls.
This page covers one part of the borough. For the full picture — fees, timelines and the council's current position — read structural calculations in Southwark.
Structural calculations for a East Dulwich project size the beams, lintels, foundations and loft floor for your specific SE22 property. A chartered engineer signs off the steelwork for knocked-through walls, rear openings and roof conversions on SE22's victorian and edwardian terraces and bay-fronted villas, and the calculations form part of the Building Regulations submission to Southwark Council.
Chartered structural engineer calculations for every residential intervention in East Dulwich — steel beams, lintels, pad foundations, wall removals, loft floor joists, underpinning. Eurocode-compliant, Building Control-ready.
Across East Dulwich, Lordship Lane, Peckham Rye, Dulwich in SE22, the dominant property is victorian and edwardian terraces and bay-fronted villas across east dulwich, with larger semi-detached houses towards dulwich and the lordship lane shopping streets. That stock shapes what structural calculations looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Southwark Council judges each on design quality and neighbour impact. We survey the specific East Dulwich property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the SE22 streetscape.

East Dulwich SE22 is dominated by Victorian and Edwardian bay-fronted terraces with the classic side return, and Southwark Council routinely approves single-storey rear and side-return extensions under Permitted Development on these houses. It's one of the busiest family-extension markets in south London. We check your street is outside the East Dulwich conservation area and any Dulwich Estate land before relying on PD.
It can. Part of the Dulwich area is managed by the Dulwich Estate scheme of management, which adds a private consent on top of council planning for some properties towards the SE22/SE21 fringe. Most core East Dulwich terraces around Lordship Lane are unaffected. We confirm whether your address carries a Dulwich Estate consent requirement as well as Southwark planning before designing.
The Victorian and Edwardian terraces of East Dulwich SE22 take a rear or L-shaped dormer loft conversion well, often combined with a side-return kitchen extension below for a full family reconfiguration. Larger semi-detached houses can take a hip-to-gable plus dormer. We design to the roof type and confirm whether full planning or a Lawful Development Certificate is the right route.
With East Dulwich property at approx £750k, £1.5m for houses, £725k for flats (Land Registry, 2024), the professional drawing fee is a small fraction of the value the work adds to SE22's victorian and edwardian terraces and bay-fronted villas. Southwark Council charges its own statutory application fee on top (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 SE22 address.
For a SE22 project across East Dulwich, Lordship Lane, Peckham Rye, Dulwich, 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 Southwark Council (8 weeks for a householder application). We carry the East Dulwich application through every officer query to the decision.
East Dulwich (SE22) sits primarily in Southwark, so applications are decided by Southwark Council. Conservation areas within SE22 include East Dulwich, Dulwich Village fringe, Peckham Rye, 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 structural calculations in East Dulwich — 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 Southwark Council Building Control or an approved inspector. On SE22'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. With East Dulwich (SE22) property at approx £750k, £1.5m for houses, £725k for flats (Land Registry, 2024), a well-designed extension or loft typically returns more than it costs in added floor area and sale value. 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 SE22 homes.

Every SE22 postcode district we draw in, the stock that dominates it and the authority that validates a structural calculation package there. SE22 fees below are the statutory England rates for 2026, not structural calculation package estimates.
| Postcode | Area | Dominant stock | What it means for a structural calculation package |
|---|---|---|---|
| SE22 | East Dulwich | Victorian and Edwardian terraces | SE22 covers East Dulwich only; Southwark Council handles the structural calculation package. |
| SE1 | Bermondsey / Borough / Waterloo | Georgian terraces, post-war flats, new-build | Adjoining district to SE22. The structural test is national, so the same approved documents apply on both sides of the Southwark line. |
| SE5 | Camberwell | Georgian villas, Victorian terraces | Adjoining district to SE22. The structural test is national, so the same approved documents apply on both sides of the Southwark line. |
| SE15 | Peckham / Nunhead | Victorian terraces, post-war estates | Adjoining district to SE22. The structural test is national, so the same approved documents apply on both sides of the Southwark line. |
| SE16 | Bermondsey / Rotherhithe | Warehouse conversions, Georgian terraces, new-build | Adjoining district to SE22. The structural test is national, so the same approved documents apply on both sides of the Southwark line. |
Roof pitch, wall build-up and plot depth change every few SE22 streets, and each one changes what a structural calculation package can achieve at that address.
