Chartered structural engineer calculations for every residential intervention in Southwark — steel beams, lintels, pad foundations, wall removals, loft floor joists, underpinning. Eurocode-compliant, Building Control-ready.
Structural calculations in Southwark, a borough of Georgian and Regency in Bermondsey and Borough; Victorian terraces in Camberwell and Peckham; Dulwich Estate controlled housing; riverside new-build, are the full measured-survey-to-submission drawing set London Borough of Southwark needs in order to determine an application: existing and proposed plans, elevations and sections at 1:100 and 1:50, a location and site plan, and the supporting statements the case officer asks for.

Chartered structural engineer calculations for every residential intervention in Southwark — steel beams, lintels, pad foundations, wall removals, loft floor joists, underpinning. Eurocode-compliant, Building Control-ready.
Housing stock in Southwark: Georgian and Regency in Bermondsey and Borough; Victorian terraces in Camberwell and Peckham; Dulwich Estate controlled housing; riverside new-build.
Character: Dulwich Estate private planning scheme affects much of SE21 and SE22; Southwark planning for rest of borough; strong heritage context.
Article 4: Article 4 for HMOs borough-wide; additional Article 4 for office-to-residential in Bermondsey and Elephant & Castle.
Steel beam (RSJ) and padstone design for opening up kitchens, knocking through reception rooms or creating open-plan layouts in your Southwark property.
Ridge beam, purlin, dormer framing and floor joist upgrade calculations — essential for every habitable loft in Southwark.
Pad, strip or trench-fill foundation design based on Southwark ground conditions, tree proximity and drain locations.
New window and door openings — steel, concrete or timber lintel specification with bearing calculations.
Sequential underpinning design, reinforced concrete slab and retaining wall calculations for Southwark basements.
Every calculation set is signed by a chartered structural engineer (CEng MIStructE or MICE) — accepted by all Building Control bodies.

Single planning or regs submission.
Planning + building regs + structural.

Every Southwark postcode district we draw in, the stock that dominates it and the authority that validates a structural calculation package there. Southwark 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 |
|---|---|---|---|
| SE1 | Bermondsey / Borough / Waterloo | Georgian terraces, post-war flats, new-build | A structural calculation package in Bermondsey / Borough / Waterloo may land with Southwark Council or Lambeth Council — SE1 crosses the boundary, and the SE1 policies map decides it street by street. |
| SE5 | Camberwell | Georgian villas, Victorian terraces | A structural calculation package in Camberwell may land with Southwark Council or Lambeth Council — SE5 crosses the boundary, and the SE5 policies map decides it street by street. |
| SE15 | Peckham / Nunhead | Victorian terraces, post-war estates | SE15 covers Peckham / Nunhead only; Southwark Council handles the structural calculation package, and Peckham / Nunhead case officers apply the SE15 conservation-area map. |
| SE16 | Bermondsey / Rotherhithe | Warehouse conversions, Georgian terraces, new-build | SE16 covers Bermondsey / Rotherhithe only; Southwark Council handles the structural calculation package, and Bermondsey / Rotherhithe case officers apply the SE16 conservation-area map. |
| SE17 | Walworth | Post-war estates, new-build towers | Walworth sits wholly inside SE17, so Southwark Council validates every structural calculation package submitted from an SE17 address. |
| SE21 | Dulwich Village | Georgian villas, Edwardian villas (Dulwich Estate) | A structural calculation package in Dulwich Village may land with Southwark Council or Lambeth Council — SE21 crosses the boundary, and the SE21 policies map decides it street by street. |
| SE22 | East Dulwich | Victorian and Edwardian terraces | SE22 covers East Dulwich only; Southwark Council handles the structural calculation package, and East Dulwich case officers apply the SE22 conservation-area map. |
| SE24 | Herne Hill | Victorian villas, Edwardian terraces | SE24 straddles a boundary: Herne Hill addresses fall to Lambeth Council or Southwark Council, so confirm which authority validates the structural calculation package before submitting SE24 drawings. |
Roof pitch, wall build-up and plot depth change every few Southwark streets, and each one changes what a structural calculation package can achieve at that address.
Conservation areas covering Southwark: Southwark Council runs 43, and Bermondsey Street, Dulwich Village, Peckham Rye are the ones Southwark owners meet most. A structural calculation package inside a Southwark conservation area loses permitted development, so the Southwark submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Camberwell Grove a structural calculation package is judged on the street elevation first.
What Article 4 removes near Southwark: Article 4 for HMOs borough-wide; additional Article 4 for office-to-residential in Bermondsey and Elephant & Castle. Before pricing a structural calculation package we check whether the SE1 address is inside the mapped area, because Southwark Council draws the Southwark boundary street by street rather than across the whole of Southwark.
What Southwark is built from: Georgian and Regency in Bermondsey and Borough; Victorian terraces in Camberwell and Peckham; Dulwich Estate controlled housing; riverside new-build. Dulwich Estate private planning scheme affects much of SE21 and SE22; Southwark planning for rest of borough; strong heritage context. That mix decides the structural calculation package route in Southwark more than the postcode does, and it is what a Southwark Council case officer reads first. A householder application costs £548 paid to Southwark Council direct, with 8 weeks to a decision once validated.

Direct answers to the questions Southwark homeowners ask every week about structural calculations.
Start a free quote →Structural fees in Southwark scale with the intervention: a single beam for a wall removal is the smallest package, a full loft or extension set (ridge beam, purlins, foundations, lintels) is larger, and basements or multi-storey work are quoted individually. Every package includes chartered engineer sign-off. See our fees.
Yes — removing or altering any load-bearing wall in your Southwark property requires structural calculations proving the replacement beam and supports can carry the loads. Building Control will not approve the work without chartered engineer-signed calculations. Even partition walls should be checked before removal.
We deliver structural calculations within 1–2 weeks of receiving the architectural drawings and site measurements. For urgent projects in Southwark, we offer a fast-track service (3–5 working days) at a small premium.
A structural survey is a condition assessment of the existing building — identifying defects, movement, subsidence. Structural calculations are engineering designs for new work — beams, foundations, loft steelwork. For most Southwark extension and loft projects, you need calculations (not a survey). We provide calculations; we can recommend surveyors if a condition survey is needed.
Yes — we offer standalone structural calculations for Southwark projects where you already have architectural drawings from another practice. If you need both drawings and structural, our Complete package bundles them at a lower combined price.
