Structural engineer Norwich for extensions, lofts and wall removals
★★★★★
Rated 5/5 by homeowners
If you are looking for a structural engineer Norwich for a wall removal, loft conversion or home extension, we help with clear calculations for older terraces, 1930s semis and post-war houses across the city.
Most of our Norwich work comes from local builders and architects who want straightforward RSJ, timber and foundation designs that Building Control can check quickly.
- Norwich house types in mind – from Victorian terraces in NR1–NR2 to 1930s semis in Hellesdon and Sprowston.
- One joined-up design that ties RSJs, joists, bearings and padstones together, so nobody is guessing on site.
- Plain-English notes so you, your architect and builder all understand what is being supported and why.
We work with homeowners, small developers, architects and builders across Norwich, Thorpe St Andrew, Eaton, Cringleford, Hellesdon, Sprowston and nearby NR postcodes.

Structural engineer Norwich – common questions
Short answers to the questions Norwich homeowners and builders ask most often.
Do you need to visit my house in Norwich?
Not always. Clear drawings, photos and basic measurements are enough for many RSJ designs, extensions and loft conversions. If we do need to see the property because the structure is unclear, we explain that first and include it in the quote.
How much does a structural engineer cost in Norwich?
Simple wall removals with one RSJ sit in the lower hundreds. Full loft or extension projects cost more because there are extra beams, checks and drawings. Send your plans and we will reply with a fixed fee before you commit.
Will Building Control accept your calculations?
Yes. We design to the Eurocodes with the UK National Annexes and set everything out in a format that Building Control officers see every day. If a Norwich inspector has questions, we answer them and adjust the pack where needed as part of the service.
Can you help with loft conversions in older Norwich terraces?
Yes. Many Norwich lofts have shallow rafters and weak collars. We design ridge beams, new joists and strengthening so the new room is safe and Building Control can sign it off.
