Builders in Nantwich
A Nantwich builder
who shows you the numbers.
Extensions, whole-house renovations and listed-building work across Nantwich and the south Cheshire market towns on an open book. Every merchant invoice visible, a fixed management fee, a fair 10% on top — typically around 11% less than a padded fixed-price quote.
Clarity in Simplicity
Why we're different
Most Nantwich builders quote you a number. We show you the numbers.
Nantwich is one of the finest historic market towns in the North West, and one of the most demanding to build in. Welsh Row, Hospital Street, Pillory Street and Beam Street carry a heavy concentration of listed buildings, timber-framed medieval houses and Georgian townhouses. The surrounding villages of Acton, Willaston, Wybunbury, Stapeley and Wrenbury add strong period cottages, farmhouses and substantial modern family homes. Working here needs conservation-area awareness, sympathetic material choices and patient site management. It also needs a builder happy for the client to see every specialist invoice — because listed-building work has a lot of them.
Built Clear runs Nantwich projects on an open book. We price your build openly from the plans, pass every merchant and specialist invoice through at cost, add one fixed management fee for the whole project, and a flat 10% on top. Nothing hidden. Every pound visible. Where a lime plaster subcontractor or a heritage joinery specialist charges a premium, you see it as it lands, not buried in a padded fixed-price number.
On like-for-like Nantwich projects that comes in around 11% below a conventional fixed-price quote. See our wider Cheshire builders page for how the model plays out across the rest of the county, or our 2026 Cheshire cost guide for real per-square-metre rates.
The Open-Book Model
Three honest numbers. That's the whole deal.
A fixed management fee
One agreed, fixed fee to run the whole project. Programmed, coordinated, delivered. Set at the start, doesn't move as the job progresses.
A fair 10% on top
A simple ten percent on real costs covers overheads and profit. No 15% loading, no padded contingencies. Sustainable for us, fair for you.
The result: typically around 11% less than a conventional fixed-price Nantwich estimate, and a build where everyone stays on the same side.

Real words from real projects
What clients say.
★★★★★
Ben and his team were meticulous in planning and really clear in their communications throughout. From start to finish, the project ran seamlessly and was actually delivered earlier than anticipated. After this positive experience, we're booking for a further renovation and extension project with Built Clear in the next six months.

Common questions
Nantwich builder FAQs.
How much do builders in Nantwich cost in 2026?
Nantwich projects vary widely because of the mix of listed and non-listed stock. Extensions and renovations on non-listed property typically run £2,000 to £2,850 per square metre. Listed-building work can add 20 to 40% depending on the fabric and consent conditions. New builds sit at £2,300 to £3,250 per square metre. On open-book pricing you see the exact merchant and specialist numbers as they land rather than a single padded figure. See the 2026 Cheshire cost guide for detail by project type.
Do you handle listed-building work in Nantwich?
Yes. Timber-framed repair, lime mortar and plaster, sash window restoration, heritage joinery — we work with proven local heritage specialists and pass every one of those invoices through at cost. Listed-building consent conditions get built into the programme at the start.
How long does a Nantwich extension or renovation take?
A single-storey rear extension typically takes 12 to 20 weeks on site. A two-storey side extension is 20 to 28 weeks. A whole-house renovation runs 6 to 12 months. Listed-building projects run longer, typically 8 to 14 months for a substantial refurbishment. The programme is agreed alongside the fixed management fee at the start.
Are you a fixed-price builder in Nantwich?
Not in the traditional sense, and on Nantwich period property a fixed price is almost always the wrong instrument. A fixed-price quote has to include a heavy risk premium against the unknowns in a timber-framed or listed building. Open-book pricing hands that saving back to you: real costs at cost, a flat 10% on top, and a fixed management fee agreed at the start.
Do you work with our own architect and heritage consultant?
Yes. Most Nantwich projects come with architects, heritage consultants and structural engineers already in place. We work alongside them. If you don't have a heritage consultant lined up yet, we can introduce you to good local practices we've worked with before.
