Structural engineers Norwich – common questions
Short answers to the questions Norwich homeowners and builders ask our structural engineers Norwich most often.
Do you need to visit my house in Norwich?

Send your plans and we will reply with a fixed quote 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.
Are you structural engineers Norwich or a single engineer?
We are a team of qualified structural engineers Norwich clients across Norfolk can call on for residential projects. Whether you use the singular "structural engineer Norwich" or the plural "structural engineers Norwich" when you search, you will reach the same experienced team. All designs are reviewed by a chartered engineer before delivery.
How quickly do structural engineers Norwich turn around designs?
RSJ beam and single wall removal designs are typically returned within 24 to 72 hours. Larger packs for loft conversions and full extensions are normally ready within 3 to 5 working days. Turnaround depends on how clear your drawings and photos are – the more detail you send, the faster we can work.
Do you cover Norfolk towns outside Norwich?
Yes. Our structural engineers Norwich practice covers the wider Norfolk area including Wymondham, Attleborough, Diss, North Walsham, Holt and villages across the NR postcode area. Most designs are prepared from drawings and photos, so distance is rarely a barrier. Send your project details and we will confirm coverage.
Can structural engineers Norwich help with chimney breast removal?
Yes. Chimney breast removal is one of the most common jobs our structural engineers Norwich handle. We calculate the RSJ or gallows bracket needed to carry the remaining stack, specify the padstones and bearings, and prepare the full calculations Building Control needs. Chimney removal designs start from £245 depending on the number of floors involved.
