Polyphant full build package — feasibility first, drawings second
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. On a Polyphant site, the brief always meets the place — Polyphant is a small rural hamlet in the PL15 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward small infill homes and converted barns.
Polyphant sits in East Cornwall — covering PL15 from Launceston, Warbstow, North Petherwin outward.

Who this is for
Polyphant runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every full build package enquiry from the use-class up.

Polyphant Full Build — local questions answered.
- 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. In Polyphant specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- What guarantees and aftercare do you offer?
- Standard twelve-month defects period, plus product and workmanship warranties on relevant elements. We're a Cornish business — you'll still find us in the same studio in five years' time.
- 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.
- How do you handle changes during the build?
- Weekly client meetings, written change requests, costed and signed before work proceeds. No surprise invoices.
- 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.
Local context
Why Polyphant is its own job.
Locally, the main planning test is usually whether the proposal remains subordinate, locally detailed and acceptable on access, drainage and neighbour amenity. 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. Which is why we scope Polyphant projects parish-up, not template-down — the PL15 context shapes the design from day one. Whether the project is on small infill homes in the centre or further out toward Launceston, the full build package response is locally tuned.
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.
What we focus on
Full Build considerations specific to Polyphant.
01
Cornish trades are a tight community; using contractors who've worked together before saves weeks on programme and arguments on site.
02
Single-contract delivery removes the gap between architect's intent and builder's interpretation — fewer change orders, less variation cost.
03
Off-grid sites need their own water, drainage and power solutions designed and procured rather than assumed.
04
Material lead times to Cornwall are longer than the M5 corridor; sequencing orders early protects the build programme.
