Design, planning and build for Treliske full build package
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. Every Treliske project we take on begins with reading the local context — Treliske is a town-edge neighbourhood in the TR1 area, where modern housing, larger gardens and edge-of-settlement plots create practical development opportunities, with a building stock that leans toward semis and bungalows.
Treliske sits in Mid Cornwall — just off the A390; covering TR1 from Truro, St Michael Penkivel, Calenick outward.

Who this is for
In Treliske the full build package brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.
Local watch-list
Local snags worth knowing before drawing a Treliske full build package.
Watch #1
Local Plan tests on isolated dwellings, plus lane access for plant and deliveries around Treliske
Watch #2
Trussed roofs and shallow foundations in the later TR1 estates, which change the structural strategy
Local proof — Most Treliske full build package clients we work with are second-time builders — they've seen the templated approach fail once already.

Treliske Full Build — local questions answered.
- 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. In Treliske specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- 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.
- 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.
- How do you handle changes during the build?
- Weekly client meetings, written change requests, costed and signed before work proceeds. No surprise invoices.
- We live in the house. Can a full build package in Treliske 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 Treliske are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.

Page purpose
How a Treliske build actually runs
This is delivery, not paperwork. The value here is programme, sequencing and a single point of responsibility for a TR1 site. In Treliske that usually means access, storage and neighbour management get planned before the first delivery arrives.
- Site set-up planned around Treliske 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
Scope
Where our work starts and stops on a TR1 project
These stages can be bought separately. Most TR1 projects use three of them.
Structural coordination
Calculations coordinated with the drawings so building control sees one consistent story.
Full design and build
One contract from first sketch to handover, with the same team on paper and on site.
Measured survey
An accurate record of what is actually there, which is where most avoidable cost is removed.
Who this is for
Our footing in Mid Cornwall
- Applications for Treliske are handled through Cornwall Council, with St Austell the nearest planning office we deal with regularly.
- Design and build are offered from the same studio, which means the person answering your Treliske questions has seen the detail built.
- Drawings, planning and building regulations are all produced in-house, so a full build package enquiry does not get passed between firms.
Planning rules change and every site is different. For the final position on your address, check with Cornwall Council as the local planning authority or the Planning Portal.

Treliske is covered from our Truro 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.
Local context
Why Treliske is its own job.
Cornwall Council's lens on Treliske is consistent: neighbour amenity, highways, drainage and the transition from built-up edge to countryside are usually the planning pressure points. 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's why we treat every Treliske project as a TR1-area job first — not a generic Cornwall job with a postcode bolted on. The semis that dominate Treliske (and continue out toward Calenick) set the tone for any full build package scheme here.
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 Treliske.
01
Off-grid sites need their own water, drainage and power solutions designed and procured rather than assumed.
02
Weather windows on Cornish coastal sites are short — getting the building watertight before autumn matters more here than in central England.
03
Cornish trades are a tight community; using contractors who've worked together before saves weeks on programme and arguments on site.
04
Material lead times to Cornwall are longer than the M5 corridor; sequencing orders early protects the build programme.
Our process
How a Treliske 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 fabric
Why Treliske homeowners pick a local studio for full build package.
