Full Build for Trethurgy (PL26)
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. The way we approach full build package in Trethurgy starts with a measured walk-round — Trethurgy is a small rural hamlet in the PL26 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward cottages and converted barns.
Trethurgy sits in Mid Cornwall — just off the A390; covering PL26 from St Austell, Bugle, St Dennis outward.
- Rural / open-countryside policy area
- ✓Local to Mid Cornwall — not a national franchise
- ✓Same team on paper as on site
- ✓One studio — design, planning and build under one roof
- ✓Measured-survey accuracy from day one

Why Trethurgy is its own job.
In Trethurgy the planning picture is specific: 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. That local reading is what makes a Trethurgy (PL26) project different from a generic Cornwall scheme — and is the whole reason we work this way. On 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.
What we focus on
Full Build considerations specific to Trethurgy.
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.

Trethurgy is covered from our St Austell run. Being a smaller place, the local detail matters more than the headline policy: lane access, neighbour proximity and what the immediate street already looks like.
Page purpose
How a Trethurgy build actually runs
This is delivery, not paperwork. The value here is programme, sequencing and a single point of responsibility for a PL26 site. In Trethurgy that usually means access, storage and neighbour management get planned before the first delivery arrives.
- Site set-up planned around Trethurgy access, parking and delivery constraints
- One programme covering trades, inspections and building control sign-off
- Materials specified for local exposure, not a generic national spec
- Weekly progress contact so decisions never hold up the programme

Trethurgy 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 Trethurgy 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.
- We live in the house. Can a full build package in Trethurgy be done while we stay put?
- Usually yes for single-storey and rear work, with a temporary kitchen or bathroom arrangement agreed before the start. Whole-house remodels and roof work in Trethurgy are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
- 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.
