Full Build for Trewoon (PL25)
Once drawings are approved, the build is the bit that decides whether you get the home you imagined or a frustrating compromise. We deliver projects on a single contract — design, drawings, approvals and construction — so the team that drew it is the team that builds it. Trewoon sits in Mid Cornwall, and that geography ends up in the drawings — Trewoon is a commuter village in the PL25 area, with everyday family housing, edge-of-village plots and quick routes to its parent town, with a building stock that leans toward older cottages and post-war semis.
Trewoon sits in Mid Cornwall — covering PL25 from St Austell, Bugle, St Dennis outward.
- Rural / open-countryside policy area
- ✓ One studio — design, planning and build under one roof
- ✓ Local to Mid Cornwall — not a national franchise
- ✓ Measured-survey accuracy from day one
- ✓ 30+ years of Cornwall Council approvals
Our process
How a Trewoon full build package project runs.
Step 1
Pre-construction
Programme, procurement, contractor briefing and site setup.
Step 2
Substructure
Foundations, drainage, ground beams — the unglamorous bit that decides everything later.
Step 3
Superstructure
Frame, roof, glazing — getting the building watertight.
Step 4
First and second fix
Services, plaster, joinery, kitchens and bathrooms.
Step 5
Snag and handover
Final inspection, building control sign-off, handover pack and aftercare.
Full builds run from twelve weeks for small extensions to eighteen months for new build family homes.
Local proof — Most Trewoon homeowners come to us after a full build package quote elsewhere felt vague on planning — we lead with feasibility instead.

Full Build considerations specific to Trewoon.
01
Off-grid sites need their own water, drainage and power solutions designed and procured rather than assumed.
02
Cornish trades are a tight community; using contractors who've worked together before saves weeks on programme and arguments on site.
03
Weather windows on Cornish coastal sites are short — getting the building watertight before autumn matters more here than in central England.
04
Single-contract delivery removes the gap between architect's intent and builder's interpretation — fewer change orders, less variation cost.
Local context
Why Trewoon is its own job.
In Trewoon the planning picture is specific: applications here usually turn on neighbour amenity, parking, overlooking and whether new work fits the rhythm of existing streets. For full build package specifically, Cornwall Council's Local Plan applies tighter tests to isolated rural dwellings here, so design rationale and policy fit need to be set out clearly from the outset. That local reading is what makes a Trewoon (PL25) project different from a generic Cornwall scheme — and is the whole reason we work this way. On older cottages in particular — the kind you'll also find toward Nanpean — the full build package brief always has to read the existing fabric first.
Planning note
Build delivery doesn't need planning, but planning conditions often dictate site setup, materials and working hours — we read every condition and build the programme around them.

FAQs
Trewoon Full Build — local questions answered.
- How do you handle changes during the build?
- Weekly client meetings, written change requests, costed and signed before work proceeds. No surprise invoices. In Trewoon specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- Are you insured?
- Public liability, employer's liability and contractor's all-risks cover are in place for every project, with certificates available before contract signing.
- Can you build from someone else's drawings?
- Yes, with a review. We'll happily build from approved drawings produced elsewhere, after a technical review to confirm the design holds up at construction stage.
- Fixed price or open book?
- Both. Fixed price suits well-defined projects with clear specs; open book suits renovations and listed work where the unknowns only reveal themselves once you start opening things up. We'll recommend the right route.
- Do you handle the whole project from drawing to finish?
- Yes — that's the model. One contract from feasibility to handover, with design, regs and build all under our roof. No coordination gap between designer and contractor.
