Project Management & Full Build in Trewennack
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 Trewennack version of this work has its own character — Trewennack is a small rural hamlet in the TR13 area, with scattered homes, lanes and a deliberately quiet settlement pattern, with a building stock that leans toward small infill homes and farmhouses.
Trewennack sits in West Cornwall — covering TR13 from Helston, Breage, Ashton outward.

The TR13 constraints that shape a full build package brief.
Watch #1
Tighter Local Plan tests on isolated rural dwellings
Who this is for
Trewennack 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.
Local context
Why Trewennack is its own job.
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. So every Trewennack job runs as a TR13-specific piece of work — local policy, local fabric, local builders. Most of our full build package work in Trewennack lands on small infill homes, with detailing that has to nod to the wider Breage streetscape.
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 Trewennack.
01
Material lead times to Cornwall are longer than the M5 corridor; sequencing orders early protects the build programme.
02
Off-grid sites need their own water, drainage and power solutions designed and procured rather than assumed.
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.
Our process
How a Trewennack 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.
FAQs
Trewennack 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 Trewennack 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.
- 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.
- 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.
Trewennack is part of Helston
Trewennack sits inside the Helston catchment — we cover both as one full build package territory.
See Full Build in Helston →Local proof — We typically have one or two full build package jobs live in the TR13 area at any time, so the local planning officers know our drawings on sight.
