Do I need planning permission for an extension in Lostwithiel?
The honest answer is that it depends on your specific address, and that is not evasion. Permitted development rights are set nationally but they are removed or narrowed in particular circumstances, and Lostwithiel has its share of them: the Conservation Area boundary, listed buildings and their curtilage, flats and maisonettes, and estates where an original planning condition removed the rights outright. 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 — just off the A38; covering PL22 from Fowey, Lerryn outward.

Page purpose
What you actually get on a Lostwithiel planning application drawings package
This is a drawings-led service. You are buying a documented, submission-ready set for a PL22 address, not a build contract. For most Lostwithiel 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 PL22 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 PL22 project
Clients in Lostwithiel take different slices of this list, and that is deliberate.

Change of use, fit-out and access documentation for Class E and mixed-use premises.
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.
Who this is for
Our footing in East 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 Lostwithiel 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.

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. Where a property sits inside a conservation area or is listed, the assessment tends to turn on materials, window detailing and how visible the change is from the street rather than floor area alone. Cornwall Council's conservation team, or the Planning Portal, is the right place to confirm what applies to a specific address.
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.

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.

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
Lostwithiel Planning — local questions answered.
- What is permitted development?
- A set of nationally granted rights allowing certain works without a planning application, subject to size, height, position and material conditions. It is not a blanket permission, and it does not apply to every property.
- How do I know if my Lostwithiel property has permitted development rights?
- Check whether the property is listed, whether it sits in a designated area, and whether the original permission carried a condition removing the rights. Cornwall Council holds that record and the Planning Portal explains the national rules.
- What is a lawful development certificate?
- A formal confirmation from the council that your proposal is lawful without planning permission. It is optional, but it protects you at resale and mortgage lenders and solicitors often ask for it.
- Does permitted development mean I can skip building regulations?
- No. They are entirely separate. A permitted development extension still has to comply with building regulations and be signed off.
- 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 proof — Most Lostwithiel homeowners come to us after a planning application quote elsewhere felt vague on planning — we lead with feasibility instead.
