Design, planning and build for Trevellas 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 TR5 site visit comes before a Trevellas sketch, every time — Trevellas is a coastal village in the TR5 area, where sea exposure, views and seasonal pressure shape most building decisions, with a building stock that leans toward rendered coastal houses and granite cottages.
Trevellas sits in North Cornwall — covering TR5 from St Agnes, Mount Hawke, Mithian outward.

Local proof — Our North Cornwall workload means a Trevellas planning application project never has to wait for an out-of-county team to drive down.

Why Trevellas is its own job.
Cornwall Council's lens on Trevellas is consistent: 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; the wider area forms part of the Cornish Mining World Heritage Site, which adds a heritage assessment layer to most material changes; coastal salt-laden air around Trevellas drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure. That's why we treat every Trevellas project as a TR5-area job first — not a generic Cornwall job with a postcode bolted on. The rendered coastal houses that dominate Trevellas (and continue out toward Mithian) 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 Trevellas.
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
Cornwall's Local Plan policies on second homes, holiday lets and principal residence restrictions affect what's likely to gain consent in some parishes.
03
Pre-app responses are not binding but they are a strong steer — and worth the fee on anything contentious.
04
Article 4 directions in some parishes remove permitted development rights you'd normally rely on elsewhere.
Our process
How a Trevellas 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
Why Trevellas homeowners pick a local studio for planning application.
Building stock
Across Trevellas (TR5) we work on granite cottages, rendered coastal houses, holiday homes, bungalows, replacement dwellings. Each stock type drives a different planning application response — rendered coastal houses in particular needs careful detailing here.
Parish & policy
Trevellas sits in the parish of Trevellas, which matters for how parish-level consultation lands on a planning application application.
Coverage
We cover TR5 from our studio, with regular planning application jobs also running in St Agnes, Mount Hawke, Mithian. Most Trevellas site visits get booked within the same week.
How quickly can you visit a Trevellas site?
Usually within the same week. Trevellas (TR5) is on our regular North Cornwall run, alongside St Agnes, Mount Hawke, Mithian. First visits are free and you'll get an honest feasibility view inside seven days.

Trevellas 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 Trevellas specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- 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.
- 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.
- 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.
Trevellas is part of St Agnes
Trevellas sits inside the St Agnes catchment — we cover both as one planning application territory.
