Treen planning application — feasibility first, drawings second
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. On a Treen site, the brief always meets the place — Treen is a coastal village in the TR19 area, where sea exposure, views and seasonal pressure shape most building decisions, with a building stock that leans toward replacement dwellings and holiday homes.
Treen sits in Penwith — covering TR19 from St Buryan, Truro, St Austell outward.

Who this is for
Treen runs the full mix — owner-occupier, holiday-let, commercial and the occasional smallholding — so we scope every planning application enquiry from the use-class up.

Coastal exposure driving fixing, render and joinery spec
Local proof — Most Treen homeowners come to us after a planning application quote elsewhere felt vague on planning — we lead with feasibility instead.

Treen Planning — local questions answered.
- 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. In Treen specifically, we'd start by checking AONB landscape sensitivity 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.
- 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.
- 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.
Local context
Why Treen is its own job.
Locally, coastal setting and landscape sensitivity mean rooflines, glazing, drainage and external materials need careful handling from the first sketch. For planning application specifically, the surrounding landscape falls inside the Cornwall Area of Outstanding Natural Beauty, so massing, height and landscape impact carry extra weight in any planning decision; coastal salt-laden air around Treen drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. Which is why we scope Treen projects parish-up, not template-down — the TR19 context shapes the design from day one. Whether the project is on replacement dwellings in the centre or further out toward St Buryan, the planning application response is locally tuned.
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 Treen.
01
Cornwall has more than thirty Conservation Areas and large stretches of AONB; planning weight on materials, mass and form is significantly higher in those zones.
02
Pre-app responses are not binding but they are a strong steer — and worth the fee on anything contentious.
03
Article 4 directions in some parishes remove permitted development rights you'd normally rely on elsewhere.
04
Cornwall's Local Plan policies on second homes, holiday lets and principal residence restrictions affect what's likely to gain consent in some parishes.
Our process
How a Treen 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.
Local fabric
Choosing a planning application team that actually knows TR19.
Building stock
Across Treen (TR19) we work on granite cottages, rendered coastal houses, holiday homes, bungalows, replacement dwellings. Each stock type drives a different planning application response — replacement dwellings in particular needs careful detailing here.
Parish & policy
Treen sits in the parish of Treen, which matters for how parish-level consultation lands on a planning application application.
Coverage
We cover TR19 from our studio, with regular planning application jobs also running in St Buryan, Truro, St Austell. Most Treen site visits get booked within the same week.
What does a first Treen consultation cost?
Nothing. We come to the property, walk the site, talk through what works on a TR19 plot and follow up with a written feasibility note inside a week — no obligation either way.

Treen sits inside the St Buryan catchment — we cover both as one planning application territory.
