Design, planning and build for Mawnan 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 TR11 site visit comes before a Mawnan sketch, every time — Mawnan is a rural parish in the TR11 area, with farmsteads, lanes and scattered homes defining its built character, with a building stock that leans toward smallholdings and rural cottages.
Mawnan sits in South Cornwall — covering TR11 from Mawnan Smith, Durgan, Truro outward.

Why Mawnan is its own job.
Cornwall Council's lens on Mawnan 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, 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; 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 Mawnan project as a TR11-area job first — not a generic Cornwall job with a postcode bolted on. The smallholdings that dominate Mawnan (and continue out toward Truro) 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 Mawnan.
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
Pre-app responses are not binding but they are a strong steer — and worth the fee on anything contentious.
04
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.
Our process
How a Mawnan 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.

Parish & policy

Mawnan Planning — local questions answered.
- How much does a planning application cost in Mawnan?
- 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. In Mawnan specifically, we'd start by checking AONB landscape sensitivity before committing to a direction.
- 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.
- 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.
- Do I need to consult my neighbours before applying?
- You don't have to — the council formally consults them — but a quiet conversation early on usually pays off. Objections from neighbours are weighed by the planning officer and can be the deciding factor on borderline schemes.
- 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.
