Permitted development in Lostwithiel — what's allowed without planning
Most Lostwithiel homeowners have more PD rights than they realise — but the Conservation Area removes the big ones (rear extensions, side extensions, cladding changes). Below is what's typically allowed on a PL22 property — and what catches people out. 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. Every Lostwithiel project we take on begins with reading the local context — Lostwithiel is a medieval town on the river Fowey, formerly the capital of Cornwall, with a strong antiques trade, a Norman church and an extensive Conservation Area, with a building stock that leans toward medieval and Georgian merchants' houses and modern infill on tight town-edge plots.
Lostwithiel sits in East Cornwall — covering PL22 from Fowey, Lerryn outward.

Lostwithiel Planning — local questions answered.
- What's permitted development in Lostwithiel?
- Single-storey rear extensions up to 3m (terraced/semi) or 4m (detached), loft conversions up to 40m³ (terrace) or 50m³ (semi/detached), and most outbuildings under 2.5m eaves. Conservation Area removes side extensions, cladding and roof extensions from PD.
- Do I need to apply for anything if it's PD?
- Legally no, but a Lawful Development Certificate (LDC) costs about £100 and gives Cornwall Council's confirmation in writing. We strongly recommend it for resale and for any neighbour disputes.
- What removes PD rights in Lostwithiel?
- Conservation Area designation, Article 4 directions, flats and maisonettes, and any deed restriction from a previous planning permission. We check all four before quoting.
- How much does a planning application cost in Lostwithiel?
- 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 Lostwithiel 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.
- 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 Lostwithiel is its own job.
Conservation Area is extensive, covering the medieval streets, the church and the riverside. Listed buildings are very common; flood zone designation affects properties near the river. That sets the scene before any design work begins. For planning application specifically, parts of Lostwithiel sit within a designated Conservation Area, which means materials, fenestration and roof pitches all need to read sympathetically with the existing streetscape. It's the kind of detail that decides whether a Lostwithiel application gets approved at eight weeks or stalls in committee. The medieval and Georgian merchants' houses that dominate Lostwithiel (and continue out toward Lanlivery) 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 Lostwithiel.
01
Article 4 directions in some parishes remove permitted development rights you'd normally rely on elsewhere.
02
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.
03
Cornwall's Local Plan policies on second homes, holiday lets and principal residence restrictions affect what's likely to gain consent in some parishes.
04
Pre-app responses are not binding but they are a strong steer — and worth the fee on anything contentious.
Our process
How a Lostwithiel 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.
