Residential structural engineer calculations right across Camden — beams and lintels, pad foundations, walls taken out, loft joists upgraded, underpinning designed. Eurocode-compliant and Building Control-ready.
Structural calculations in Camden, a borough of Victorian and Edwardian terraces, are the full measured-survey-to-submission drawing set London Borough of Camden 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 Camden — steel beams, lintels, pad foundations, wall removals, loft floor joists, underpinning. Eurocode-compliant, Building Control-ready.
Housing stock in Camden: Victorian and Edwardian terraces, Georgian townhouses in Bloomsbury and Hampstead, post-war mansion blocks, modern developments in King's Cross.
Character: Creative, affluent in Hampstead and Primrose Hill; dense mixed-use around Camden Town and Kings Cross; academic character in Bloomsbury.
Article 4: Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas.
Basement policy: under Policy A5 a single-storey basement may not exceed 50% of the garden area, and a second storey below ground is generally refused outside commercial zones. The engineering follows from that limit rather than the reverse — retaining wall design, the underpinning sequence and the slab are all sized to whatever the policy leaves available.
Steel beams and padstones for the Camden ground floor that loses a wall: a kitchen opened toward the garden, two receptions run into one, or the whole plan cleared front to back.
The ridge beam, the purlins holding it, dormer framing and an upgraded floor. Every habitable Camden loft needs those numbers on paper before Building Control will look at it.
Foundation design — pad, strip or trench-fill — against Camden's ground, the trees standing near the works and the drain runs underneath. The borough is 79.1% built up across 2,177.9 hectares, so there is rarely room to shift a dig sideways.
A new opening in a wall needs a lintel sized for it, steel or concrete or timber, with the bearing at either end proved rather than eyeballed.
Underpinning set out in sequence, the reinforced slab, and retaining wall design for a Camden basement, which is exactly where the borough's own policy starts to bite.

The Camden districts we calculate in, with the prevailing stock in each and the body validating the work there. Figures in the table are 2026 statutory England rates, quite separate from any engineering fee.
| Postcode | Area | Dominant stock | What it means for a structural calculation package |
|---|---|---|---|
| NW6 | Kilburn / West Hampstead / Queen's Park | Mansion blocks, post-war flats | NW6 crosses the Camden and Brent line through Kilburn, West Hampstead and Queen's Park, so confirm which authority validates before calculations go in with the drawings. |
| W1T | Fitzrovia | Georgian terraces, Victorian mansion blocks | A structural calculation package in Fitzrovia may land with Camden Council or Westminster City Council — W1T crosses the boundary, and the W1T policies map decides it street by street. |
| WC1A | Bloomsbury | Victorian and Edwardian terraces | Bloomsbury sits wholly inside WC1A, so Camden Council validates every structural calculation package submitted from an WC1A address. |
| WC1H | Bloomsbury / Cartwright Gardens | Victorian and Edwardian terraces | WC1H covers Bloomsbury / Cartwright Gardens only; Camden Council handles the structural calculation package, and Bloomsbury / Cartwright Gardens case officers apply the WC1H conservation-area map. |
| WC1N | Bloomsbury / Russell Square | Victorian and Edwardian terraces | A structural calculation package at an WC1N address in Bloomsbury / Russell Square is determined by Camden Council under its own Local Plan policies for Bloomsbury / Russell Square. |
| WC1R | Holborn | Victorian and Edwardian terraces | WC1R is Holborn and nothing else. Camden handles the structural package, and the district's conservation-area map applies to anything showing on the outside. |
A Bloomsbury terrace and a Highgate villa share neither a pitch nor a wall build-up nor a plot depth, and the calculation moves with every one of those.
Conservation areas covering Camden: Camden Council runs 40, and Hampstead, Primrose Hill, Bloomsbury are the ones Camden owners meet most. A structural calculation package inside a Camden conservation area loses permitted development, so the Camden submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Fitzrovia a structural calculation package is judged on the street elevation first.
What Article 4 removes near Camden: Article 4 removes permitted development for HMO conversions (C3 to C4) across the borough, plus restrictions on basement extensions in 12 conservation areas. Before pricing a structural calculation package we check whether the N1C address is inside the mapped area, because Camden Council draws the Camden boundary street by street rather than across the whole of Camden.
Digging below a Camden property: Camden's basement policy (Policy A5) restricts single-storey basements to 50% of garden area; double-storey basements generally refused outside commercial zones. Where a structural calculation package in Camden involves excavation that is read beside the Party Wall etc. Act 1996, which needs two months notice for a Camden dig within 3 m of a neighbour, and Camden Council expects the N1C ground conditions addressed in the application.
Camden housing stock: Victorian and Edwardian terraces, Georgian townhouses in Bloomsbury and Hampstead, post-war mansion blocks, modern developments in King's Cross. Creative, affluent in Hampstead and Primrose Hill; dense mixed-use around Camden Town and Kings Cross; academic character in Bloomsbury. Read that before choosing a structural calculation package route in Camden — construction, not postcode, sets what is achievable. Camden Council charges £548 for a householder application and has 8 weeks to determine it.

What Camden owners and their builders ask us about structural calculations, answered without a sales pitch attached to it.
Start a free quote →What it costs depends on how much structure is changing. One beam over one opening is the small end. A full loft or extension package, ridge through purlins to foundations and lintels, is the middle. Basements, and anything spanning several storeys, get quoted individually. Chartered sign-off is included throughout. See our fees.
Yes, every time. A load-bearing wall coming out of a Camden house needs calculations proving the new beam and its bearings handle everything above them. No completion certificate gets issued until a chartered engineer has signed that off. Walls that merely look like partitions are worth checking first.
Once the drawings and the site dimensions have reached us, reckon on a fortnight, sometimes half that. Where a Camden job cannot wait, a small premium buys the fast track and the calculations come back inside five working days.
Two different things entirely. A structural survey looks at the building you already have and reports movement, subsidence and defects. Calculations are a design for the building you want: beam, foundation, loft steel, each proved against the load it takes. Camden extension and loft work almost always needs the second of those. If a condition report is genuinely what you were after, we can recommend somebody who writes them.
Yes. If the scheme has already been drawn by another practice, we calculate against their drawings as issued. If you would rather we drew it too, the Complete package carries both for less than the two bought apart.

If your property sits on a boundary, here are the neighbouring options.
Camden lodged 1,295 planning appeals over the period. Of those, 1,079 were decided and 285 allowed, 26.4%; the remaining 216 closed without being either allowed or dismissed. A sixth of everything appealed here never reached a verdict at all, which is the plainest argument there is for settling the structure before the application rather than after a refusal. One chartered team does both halves.
