Engineer's calculations for a Evington project — steel beams sized, padstones and load paths worked out and a signed calculations package your builder and Leicester City Council's building control can build from, delivered in days and revised free until it is approved.
Leicester City Council granted 87% of the householder planning decisions it made in its latest published year — level with the 87% England-wide householder average. The two Evington conservation areas — the village and the footpath — protect the old core and its green setting, shaping extension design nearby, which is where a policy-literate drawing pack earns its keep. Its dominant Victorian (1837–1901), interwar (1918–1939) and postwar (1945–1970) housing stock sets the design brief on most streets.
Class A and Class B set the thresholds — a rear dormer to 40m³ on a terrace or 50m³ on a semi or detached, and a single-storey rear extension to 3m on a terrace or 4m on a detached house — beyond which Leicester City Council needs a full application. Evington carries at least one Article 4 direction, and conservation areas including Evington village, Evington footpath and Spinney Hill Park remove those rights outright, so we confirm your exact address before a line is drawn. A validated householder application in Evington is determined against an 8-week statutory target.
Evington Village (the historic core with the conservation area and old cottages), Evington Lane (suburban semis lining the route out to the village), Downing Drive (postwar semi-detached estates with generous plots), Goodwood (later suburban housing on the eastern edge), Coleman Road (denser interwar and Victorian streets towards the city) and Spinney Hills (Victorian terraces framing Spinney Hill Park) — these are the Evington pockets our drawings cover most. Heritage designations here include Evington village, Evington footpath and Spinney Hill Park. Leicester City Council weighs each proposal against the Leicester Local Plan and the Evington conservation area appraisals, where the interwar and postwar semis are policed for spacing and building line so paired houses retain their suburban rhythm. On roofs the borough is hipped roofs on the interwar and postwar semis and gabled slate roofs on the older village houses, over interwar and postwar semi-detached houses with gardens, Victorian terraces on the streets closer to the city and larger detached properties around Evington village.
The moment a wall comes out or a new floor goes in, something has to carry the load that wall or floor was holding — and building control will not accept "it looks strong enough". The engineer traces the load path: the weight of the roof, floors and walls above is gathered into a beam, the beam is sized in steel or timber to carry it within safe deflection, and that load is passed through padstones into the masonry and down to the ground. On Evington's interwar and postwar semi-detached houses with gardens, Victorian terraces on the streets closer to the city and larger detached properties around Evington village, the spans and loads differ house to house, so every calculation is specific to the property.
The deliverable is two things that work together: the calculations, which show the maths an approved inspector can check, and the structural drawings, which turn that maths into something a builder can order and fit — a beam schedule with sizes and lengths, bearing and padstone details, and connection notes. The two Evington conservation areas — the village and the footpath — protect the old core and its green setting, shaping extension design nearby, and the calculations are drawn to sit alongside the architectural set rather than contradict it. Everything is signed by a chartered or incorporated engineer carrying professional indemnity insurance.
Older Evington stock — the kind found across Evington village, Evington footpath and Spinney Hill Park — often hides the real structural question: shallow Victorian foundations, timber that has been notched by past work, or a wall that turns out to be load-bearing when the drawings assumed otherwise. The Evington village and Evington footpath conservation areas carry heritage controls, and the 2022 HMO Article 4 extension into the Spinney Hills fringe means conversions to small HMOs there need planning permission. A survey-based calculation catches this before the wall is opened, not after.
Building control needs an engineer's calculations whenever you change how the building carries load. On a typical Evington project that means any of these:
We size the steel, work the padstones and bearings, trace the load to the foundations and issue a signed calculations package and a beam schedule for Leicester City Council's building control — coordinated with your architectural drawings so the beam that is calculated is the beam that is drawn and the beam that is ordered.
Below is Leicester City Council's real householder decision record, drawn from official planning statistics and refreshed as new data lands. Leicester grants the large majority of householder applications, and in Evington the constraints run from the village conservation core to the protected semi-detached suburban streets. Structural calculations sit behind building control rather than planning, but the same wave of loft, extension and knock-through work that drives these decisions is exactly what needs an engineer's package.

Building control approves structural work by checking the numbers, not by looking at the finished steel. Leicester City Council's inspector, or an approved inspector acting for you, reads the calculations to confirm the beam is deep enough for its span, that deflection stays within limits so ceilings do not crack, that the bearing length and padstones spread the point load into masonry that can take it, and that the load has somewhere to go all the way to the ground. Across Evington Village, Evington Lane and Downing Drive, the recurring issue is a beam sized off a rule of thumb that the actual span will not support.
The interwar and postwar semis are policed for spacing and building line so paired houses retain their suburban rhythm. We issue calculations detailed enough to be signed off without a query, coordinate them with the architect's drawings so nothing conflicts on site, and stay available to revise if the builder finds the Evington property is not quite as the survey assumed — free, until the work is approved.
We calculate beams, openings and floors on the period and modern stock across the borough. A few of the Evington neighbourhoods where structural packages come up most often:

Different jobs load the building differently, so each needs its own calculation. This is what the common Evington projects typically require.
| Project | Typical structure | What the calculation proves | Signed off by |
|---|---|---|---|
| Wall knock-through | Steel beam on padstones | Span, deflection and bearing | Building control |
| Loft conversion | New floor beams and ridge/purlin steels | Floor loading and roof support | Building control |
| Rear or side extension | Opening beam plus extension roof and floor | Combined loads and foundations | Building control |
| Basement or underpinning | Retaining and foundation design | Ground and adjacent-building loads | Building control & party wall |
On older Evington stock around Evington village and Evington footpath, shallow foundations and altered structure often mean the calculation drives the design rather than following it.
A fixed process built around building control rather than planning — most calculation packages are ready within five days of the architectural drawings.
Send us your Evington postcode and the architect's drawings or a sketch. We confirm what structure the project needs, flag any load-bearing wall or foundation question, and tell you exactly what the calculation package will cover.
Where the loads are not obvious — an unknown wall, an old alteration, a deep span — we survey the property so the beam is sized on what is really there, not an assumption.
A chartered or incorporated engineer sizes the steel, works the padstones and load path, and issues the signed calculations and a beam schedule coordinated with your Evington architectural set.
We submit the calculations to Leicester City Council's building control or your approved inspector, answer queries, and revise free if the build uncovers something the survey could not see.
Whenever you change how the building carries weight — removing or opening a load-bearing wall, converting a loft, building an extension, or inserting a beam or column. Leicester City Council's building control needs an engineer's calculation to approve any of these before the steel goes in. A Evington project that only redecorates or moves a non-structural partition does not, but almost anything that opens the structure does.
No — they are a separate, later step. Planning permission decides whether Leicester City Council will allow the change; structural calculations prove the change is safe to build and are submitted to building control, not to the planners. Many Evington projects that need no planning permission at all — an internal knock-through, a permitted-development loft — still need a full engineer's calculation before work can lawfully start.
A chartered or incorporated structural engineer, carrying professional indemnity insurance, who takes responsibility for the numbers. Leicester City Council's building control, or an approved inspector acting on your behalf, then checks and signs them off. Your builder cannot self-certify a steel beam, and an unsigned calculation will not be accepted — the engineer's signature and insurance are what make the package one building control will approve. This applies to your Evington address specifically.
Yes — a beam over a removed wall is the most common calculation we do. We work out the load the wall was carrying, size a steel or timber beam to span the opening within safe deflection, and detail the padstones that spread its weight into the masonry each side. The result is a beam schedule your Evington builder can order and Leicester City Council's inspector can approve, with the load traced all the way to the foundations.
Sometimes. Where the loads are clear from the drawings we can calculate directly, but Evington's older stock often hides surprises — a wall that turns out to be load-bearing, notched or altered joists, or shallow foundations near Evington village and Evington footpath. In those cases a short structural survey means the beam is sized on what is really there, which avoids a redesign once the builder opens the wall. Leicester City Council is the decision-maker.
We price each Evington package on the number of beams and the complexity — a single knock-through is straightforward, a whole-house loft-and-extension scheme has several elements — and send a fixed, no-obligation quote within one working day. It covers the calculations, the beam schedule and free revisions until Leicester City Council's building control approves. Call 020 7864 7245 to start.
