Frequently Asked Questions

Here are some of the most frequently asked questions we receive:

Do I Need Structural Calculations For A House Extension In Didsbury Or Manchester?
Yes. Any home extension that involves removing load-bearing walls, adding new floors, or installing steel beams requires structural calculations. These ensure your design is safe, compliant with Building Regulations, and approved by Building Control. Our structural engineers in Didsbury provide full structural calculations for home extensions and loft conversions.
How Long Do Structural Calculations Take To Complete?
Most residential projects, such as extensions or loft conversions, are completed within 5–10 working days from instruction. Larger or more complex designs may take longer, depending on the amount of detailing required.
Can You Work From My Architect's Drawings?
Absolutely. We regularly collaborate with architects and builders across Greater Manchester. If you already have planning or architectural drawings, our engineers can prepare the structural calculations directly from them.
What Information Do I Need To Get A Quote?
Simply send us your existing and proposed floor plans (PDF or DWG format) and a short description of the work , for example, “first-floor extension” or “RSJ for wall removal.” We'll review the drawings and provide a fixed-fee quote with no hidden costs.
Are Your Calculations Accepted By Building Control?
Yes. Every package we produce is Building Control-ready, complete with full calculation sheets, structural notes, and beam connection details. Our work is widely accepted across Manchester councils and throughout the UK.
Do You Cover Areas Outside Didsbury And Manchester?
Yes, we provide structural design services across Greater Manchester and nationwide , including Stockport, Sale, Altrincham, Bolton, Wigan, and Cheshire. We also offer remote services for clients anywhere in the UK.
How Much Do Structural Calculations Cost?
Prices vary depending on scope, but most home extensions or loft conversions start from £650–£1,500, including Building Control-ready documents. We always provide a clear written quote before starting any work.
Can You Design Steel Beams (RSJs) For Open-Plan Spaces?
Yes. We specialise in RSJ and beam calculations for wall removals, bi-fold door openings, and open-plan layouts. Our designs ensure the structure remains strong while giving you the bright, open space you want.
What Happens After I Receive The Calculations?
