Planning approved in St Austell, so what happens now?
An approval notice feels like the finish line and is really the starting gun. Before anyone digs in St Austell, three things need dealing with: the conditions attached to the consent, the building regulation package, and the structural design. Conditions in particular catch people out, because some of them are pre-commencement, which means work started before they are discharged is technically unauthorised. 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. Reading St Austell on the ground is half of the full build package job — St Austell is the principal town of mid-Cornwall, historically the centre of the china clay industry and now a substantial market town with the Eden Project on its doorstep, with a building stock that leans toward Georgian townhouses and Edwardian villas.
St Austell sits in Mid Cornwall — just off the A390; with Truro the closest city; covering PL25 from Mevagissey, Carlyon Bay outward.

Why St Austell is its own job.
Around St Austell (PL25), conservation Area covers the historic centre. The china clay legacy shapes the surrounding landscape and creates substantial brownfield redevelopment opportunities. For full build package specifically, parts of St Austell sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape. Reading St Austell properly up front saves more time than any drawing tool ever will. Most of our full build package work in St Austell lands on Georgian townhouses, with detailing that has to nod to the wider Carlyon Bay streetscape. On older stock, the practical constraint is usually joinery, render and roof line rather than the extension itself. We draw those details out early so a full build package submission is not sent back for missing information. Confirm listing status with the local planning authority before assuming permitted development. Exposure is the real design driver near the water: wind-driven rain, salt and driving damp push detailing towards better weathering, sheltered openings and robust fixings. Where an AONB or coastal policy applies, visual impact usually carries more weight than size.
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 St Austell.
01
Single-contract delivery removes the gap between architect's intent and builder's interpretation — fewer change orders, less variation cost.
02
Material lead times to Cornwall are longer than the M5 corridor; sequencing orders early protects the build programme.
03
Weather windows on Cornish coastal sites are short — getting the building watertight before autumn matters more here than in central England.
04
Cornish trades are a tight community; using contractors who've worked together before saves weeks on programme and arguments on site.
Page purpose
How a St Austell build actually runs
This is delivery, not paperwork. The value here is programme, sequencing and a single point of responsibility for a PL25 site. In St Austell that usually means access, storage and neighbour management get planned before the first delivery arrives.
- Site set-up planned around St Austell 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

St Austell Full Build — local questions answered.
- What is a pre-commencement condition?
- A condition that has to be discharged before any work begins, commonly covering materials, drainage strategy, ecology or construction management. Starting work before discharging one can invalidate the permission, so it is worth checking the notice line by line.
- How long does planning permission last?
- Permissions normally carry a time limit within which work must begin, stated on the decision notice itself. Check the wording on yours rather than relying on a general rule.
- Do I need new drawings after approval?
- Yes. The approved drawings show the scheme; the building regulation and construction package shows how it is built. That second set is what the builder and building control work from.
- When should I get prices?
- Once the technical drawings exist. Pricing from planning drawings alone produces quotes that are not comparable, because each builder is filling in the missing detail differently.
- How do you handle changes during the build?
- Weekly client meetings, written change requests, costed and signed before work proceeds. No surprise invoices. In St Austell specifically, we'd start by checking the Conservation Area boundary 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.
