★★★★★

We've used CONCRAFT on three buy-to-let refurbishments now. Fixed price, fixed date, and the properties are always handed back rental-ready.

DM

★★★★★

Our loft conversion was finished a week early and the quality of the joinery is honestly better than the rest of the house.

SP

Having one project manager accountable for every trade made all the difference. Weekly updates meant we always knew where we stood.

How we work

Assessment through to handover

Every project is run through the same four stages, so you always know what's happening, what's next, and who's responsible for it.

01
Assessment
We survey the property, understand the brief and the constraints, and set out what's achievable.
02
Planning
Design, specification, costing and programme are agreed and fixed before a single tool is on site.
03
Build
Our trades deliver the works to programme, with a dedicated manager reporting on progress weekly.
04
Handover
Snagging, sign-off and documentation are completed before we hand back a finished space.

Yes. As main contractor we manage planning submissions, building control sign-off and any structural or party wall requirements as part of the planning stage — you don't need to coordinate this yourself.

Every project starts with a site assessment, followed by a fixed quote based on an agreed scope of works. Any changes during the build are costed and approved by you before we proceed — no surprise invoices.

The majority of work is carried out by our own in-house, insured trades. Where specialist subcontractors are required, they work under our direct site management to the same standard.

Timelines depend on scope, but a single-storey extension typically runs 10–16 weeks and a full refurbishment 4–8 weeks once planning and design are signed off. You'll receive a full programme at the planning stage.

Yes — our property refurbishment service is built around fixed costs and fixed completion dates, with weekly progress reporting so you can plan lettings or resale with confidence.
