Design, planning and build for Mullion 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. What works on a TR12 plot rarely works elsewhere — Mullion is the largest village on the Lizard Peninsula, AONB-designated, with a fifteenth-century church, a working cove and the highest concentration of period housing on the peninsula, with a building stock that leans toward 1960s coastal bungalows and Edwardian guesthouses.
Mullion sits in Lizard Peninsula — covering TR12 from The Lizard outward.

Why Mullion is its own job.
Cornwall Council's lens on Mullion is consistent: mullion Conservation Area covers the village centre; the wider parish is entirely within the AONB and includes Heritage Coast designation. Cliff-edge and coastal margin sites face the strictest controls in West Cornwall. For planning application specifically, parts of Mullion sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape; 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 Mullion drives detailing choices — fixings, render systems and timber treatments all need to be specified for exposure; 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 Mullion project as a TR12-area job first — not a generic Cornwall job with a postcode bolted on. The 1960s coastal bungalows that dominate Mullion (and continue out toward The Lizard) 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 Mullion.
01
Cornwall's Local Plan policies on second homes, holiday lets and principal residence restrictions affect what's likely to gain consent in some parishes.
02
Pre-app responses are not binding but they are a strong steer — and worth the fee on anything contentious.
03
Tree Preservation Orders, ecology surveys and neighbour consultation responses can change the validation list mid-application.
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 Mullion 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

Building stock
Across Mullion (TR12) we work on granite cottages around the church, Edwardian guesthouses, 1960s coastal bungalows, modern AONB-sensitive replacement dwellings. Each stock type drives a different planning application response — 1960s coastal bungalows in particular needs careful detailing here.

Mullion Planning — local questions answered.
- How much does a planning application cost in Mullion?
- 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 Mullion specifically, we'd start by checking the Conservation Area boundary 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.
- 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.
- 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.
