High-quality, fully managed design & build across Cheshire — Alderley Edge, Wilmslow, Knutsford and Warrington. Fully managed design & build across Cheshire and the wider North West.
A significant structural renovation of our downstairs — removing internal walls to create a large open-plan living space, a new downstairs WC, new flooring throughout, a brand-new kitchen and patio doors. The quality of workmanship has been outstanding and the project was completed within the agreed timescales. Any minor snags were dealt with promptly, often almost immediately.
We started 2025 with a 2-storey chimney being taken out. The lads did such a good job we gave them the rest of our renovation — two small extensions, a new downstairs toilet and kitchen, upstairs bathroom, a bedroom move and renovation, finishing with a full back garden renovation. We've had many comments on how good the work looks, especially the brickwork.
We've recently had a knock-through between the lounge and dining room along with other internal and brick work. We're extremely pleased with the quality — everything finished to a high standard, the team were professional, tidy and clearly took pride in what they were doing. Communication with Craig was great throughout and they stuck to the agreed timeline.
After getting a few quotes for our kitchen, we chose Cheshire Design & Build NW and I'm glad we did. They turned up when they said they would, kept us updated, and got on with the job without any fuss. The finished kitchen looks fantastic. Reliable, respectful, and they clearly take pride in their work.
Excellent. Craig replied immediately and viewed the job. A detailed price and timeline was sent. Once the job was underway problems occurred — not Craig's fault — new plans were made and the job was done. Communication was 100%, that's important for me, and a cleaner is sent in at the end of the work. A great job done. Would definitely recommend.
Brilliant company, amazing team. Came to fit a lintel for me and brick up the outside of the house. The job was finished quickly and efficiently — very friendly and knowledgeable. Thank you so much, highly recommend.
This company has been the best to work with in terms of professionalism and quality — not like other companies I have worked with in the past. 10/10 service 👍
Highly recommend! Craig was very reliable and the quality of workmanship was outstanding! Thank you!
Great lads, very polite, showed up on time and did a great job.

The quiet discipline under every renovation
Most of our kitchen and extension projects hinge on a structural alteration somewhere — a knock-through between kitchen and dining, a goal-post steel for the full rear extension, a removed chimney breast on the first floor. We've done enough of them that the engineer, the steel supplier and the building control officer we work with are all on a first-name basis.
Whether it's a single RSJ above a reformation opening or a pair of spanning beams across a wide rear extension, the calculations, the steel order, the propping, the install and the making-good come from one team.
From calcs to cleaned-up skirting
The structural-alteration process has a lot of moving parts — engineer, building control, steel supplier, propping, plastering. We run them all.
- Engineer's Calculations — Structural engineer's report, calcs and drawings — specifying the steel, padstones and any temporary works.
- Building Control Submission — Building Notice or Full Plans submission, inspection coordination and final completion certificate.
- Temporary Propping — Acrow props, needle beams and lintels to support the wall safely before cutting.
- RSJ & UB Installation — Universal beam or RSJ lifted, seated on padstones, and packed with slate where needed.
- Goal-Post & Paired Steels — Full-width kitchen/dining openings with twin beams, vertical posts and welded cleats — engineered rigid.
- Fire Protection — Intumescent paint or plasterboard fire-casing to meet 30- or 60-minute fire resistance as required.
- Making-Good — Plastering, skirtings, architraves and flooring joined back in — the join should look like the wall was never there.
- Redecoration — Final coats and finishes so the room is handed back decorated, not just structurally complete.

Structural Alterations FAQs
Do I need an engineer's calc to remove a wall?
Yes — any load-bearing wall (and most internal walls built before the 1980s are) needs a structural engineer to calculate the replacement steel or lintel. We include the engineer's fees, calculations and drawings in our all-in quote.
Do I need building regulations approval?
Yes — building control must be notified and sign off load-bearing alterations. We submit a Building Notice or Full Plans application on your behalf, coordinate the inspection visits, and issue you the completion certificate at handover.
How much does a knock-through cost?
Every structural alteration is individually quoted — the cost depends on the span, the steel specification and the making-good required. After a free site visit we provide a fully itemised, all-in written quotation covering the engineer, building control and the build, with no hidden costs.
How long will the work take?
Lead times typically run from several weeks to several months, depending on the scope of the work. We confirm the programme as part of the written quotation following the site visit.
Can I stay in the house?
Yes. The rest of the house stays sealed and usable. You'll want to be out of the specific room for a short period while we're cutting and propping, but the rest of the property stays fully habitable.
Do you handle older houses with uncertain construction?
Yes — we work on Victorian terraces with lime-mortar solid-brick walls, 1930s semis with cavity brick, and stone-built Cheshire properties where the original build detail is anyone's guess until we open it up. Our engineer designs a solution once we've exposed what's actually there.
