FAQs

Do I need structural calculations for a home extension or loft conversion in Stockport?
Yes. Building Control will ask for structural calculations to prove the design is safe and compliant. We produce calculations and drawings for both home extension Stockport projects and loft conversion Stockport designs.
How long do structural calculations take?
Most small to medium projects are turned around quickly once we have the drawings and information. If you have a tight deadline, tell us and we will prioritise where possible.
Can you work from my architect’s drawings or a simple sketch?
Yes. We can work from planning or measured drawings. If you do not have full plans yet, clear sketches and photos are fine for a quote and early advice.
What information do you need to give me a quote?
Your address, drawings or sketches, a short scope description, preferred span widths or openings, and any known site constraints. Photos of the existing structure help.
Are your calculations accepted by Building Control?
Yes. Our packages are prepared for UK Building Regulations and are issued in a format Building Control can check with ease.
Do you cover areas outside Stockport?
We cover Stockport, Greater Manchester, and nearby towns such as Cheadle, Bramhall, Hazel Grove, Heaton Moor, and Sale. If you are further out, ask and we will advise.
Can you design RSJ beams for open-plan spaces and wide bi-folds?
Yes. We design steels for knock-throughs, rear extensions, and large openings, including bearings, padstones, posts, and connection details.
What about loft specifics like dormers, ridge beams, and stairs headroom?
We design ridge beams, purlins, trimmers, dormer framing, and floor upgrades. We also check stair opening trims and advise on practical headroom and load paths.
Do I always need a site visit?
Not always. Many domestic projects are completed from drawings, photos, and a brief call. If a site visit will add value, we will recommend it.
How much do structural calculations cost?
We give a fixed fee once we see your drawings and scope. No hidden extras. If the brief changes, we confirm any update before proceeding.
What happens after I receive the calculations and drawings?
You pass them to your builder and Building Control. If questions come back, we respond and make reasonable clarifications so the approval goes through smoothly.
