Design, planning and build for Trelights planning application
We prepare and submit planning applications to Cornwall Council and, where relevant, the Isles of Scilly authority — handling drawings, statements, validation queries and officer negotiation from start to determination. A PL29 site visit comes before a Trelights sketch, every time — Trelights is a rural parish in the PL29 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward converted barns and farmhouses.
Trelights sits in North Cornwall — covering PL29 from Port Isaac, Truro, St Austell outward.
- Rural / open-countryside policy area
- ✓ Cornwall Council regulars across every sub-area
- ✓ rural policy area experience built into the fee
- ✓ Local to North Cornwall — not a national franchise
- ✓ Same team on paper as on site
Local proof — We typically have one or two planning application jobs live in the PL29 area at any time, so the local planning officers know our drawings on sight.

Why Trelights is its own job.
Cornwall Council's lens on Trelights is consistent: open-countryside policy, access lanes, drainage and agricultural building history all need to be addressed before drawings go too far. For planning application 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 Trelights project as a PL29-area job first — not a generic Cornwall job with a postcode bolted on. The converted barns that dominate Trelights (and continue out toward St Austell) set the tone for any planning application scheme here.
Planning note
Cornwall Council's planning team is among the busiest in the South West. A clean, well-documented submission moves through validation faster than a bare-minimum one.
What we focus on
Planning considerations specific to Trelights.
01
Tree Preservation Orders, ecology surveys and neighbour consultation responses can change the validation list mid-application.
02
Article 4 directions in some parishes remove permitted development rights you'd normally rely on elsewhere.
03
Cornwall's Local Plan policies on second homes, holiday lets and principal residence restrictions affect what's likely to gain consent in some parishes.
04
Pre-app responses are not binding but they are a strong steer — and worth the fee on anything contentious.
Our process
How a Trelights planning application project runs.
Step 1
Initial review
We assess constraints — Conservation Area, AONB, listed status, Article 4, TPOs, flood zone.
Step 2
Strategy
We recommend the right application type and likely fee, programme and supporting documents.
Step 3
Drawing and statement preparation
Plans, elevations, sections, block and location plans, plus DAS and any heritage or ecology input.
Step 4
Submission and validation
We upload to the Planning Portal, pay the council fee on your behalf and respond to validation requests.
Step 5
Determination
We monitor consultation, respond to officer queries and negotiate amendments where it improves the chances of approval.
Householder applications are typically eight to twelve weeks from validation; full planning runs thirteen to sixteen weeks; major or contentious schemes can take longer.

Trelights Planning — local questions answered.
- Can you submit a retrospective application?
- Yes. We regularly handle retrospective applications — sometimes after enforcement contact, sometimes voluntarily before sale. Honesty in the supporting statement is the difference between approval and refusal. In Trelights specifically, we'd start by checking the latest parish-level planning history before committing to a direction.
- How much does a planning application cost in Cornwall?
- Cornwall Council charges a fixed national fee — currently £258 for a householder application and £578 for a single new dwelling. Our fee for the drawings, statements and submission sits separately and depends on project complexity.
- Do you handle listed building consent?
- Yes. Listed Building Consent runs alongside planning where works affect a listed structure, including some interior alterations. The drawing detail and Heritage Statement are fundamentally different from a standard planning pack.
- What's the difference between full planning and householder?
- Householder covers extensions, outbuildings and alterations to a single dwelling. Full planning is needed for new dwellings, change of use, and anything affecting curtilage subdivision. We'll confirm which route fits at first review.
- What if the council asks for more information after submission?
- Common, and usually fixable. Validation requests, ecology comments, highways queries and design tweaks all get handled by us inside the application — no extra fee unless the scope changes substantially.
Trelights is part of Port Isaac
Trelights sits inside the Port Isaac catchment — we cover both as one planning application territory.
