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 — just off the A39; covering TR5 from St Agnes, Mount Hawke, Mithian outward.

Who this is for
In Trevellas the planning application brief is almost always a private homeowner improving a forever home — so we lead with feasibility and long-term value, not show-home rhetoric.
Page purpose
What you actually get on a Trevellas planning application drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a TR5 address, not a build contract. For most Trevellas householders that means a measured survey, an honest feasibility view, then the drawings the council and your builder both need.
- Measured survey and existing drawings before any proposal is drawn
- A written planning route for the TR5 address, including whether permitted development is realistically available
- Proposed plans, elevations and site plan at the scales the authority expects
- Submission and validation handling, plus responses to officer queries
Scope
Where our work starts and stops on a TR5 project
These stages can be bought separately. Most TR5 projects use three of them.
Planning application drawings
Existing and proposed plans, elevations, site and block plans drawn to validation standard.
Construction and technical drawings
1:10 and 1:20 details for the parts of the job builders normally have to guess at.
Building regulation drawings
Full Plans sets with sections, construction notes and coordinated structural information.
Heritage and design statements
Written justification where designation makes the design case as important as the drawing.
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 North Cornwall
- Designated-area work is routine here, so heritage and landscape statements are produced alongside the drawings rather than outsourced.
- Drawings, planning and building regulations are all produced in-house, so a planning application enquiry does not get passed between firms.
- Design and build are offered from the same studio, which means the person answering your Trevellas questions has seen the detail built.
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.

Trevellas is covered from our St Agnes 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 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.
FAQs
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.
- We live in the house. Can a planning application in Trevellas 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 Trevellas are often easier if you move out for a few weeks. We set that expectation at feasibility stage rather than halfway through.
- 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.
