House Extension Planning Permission in
Falmouth
Falmouth homeowners often assume an extension automatically needs planning permission, or automatically doesn’t – neither is reliably true. Our free desktop study checks your specific project against permitted development limits, the Prior Approval route, and Falmouth’s local rules before you spend a penny on anything else.

There are genuinely three different routes an extension in Falmouth might take: straightforward permitted development with no application needed, the faster Prior Approval process for larger single-storey rear extensions (a 42-day decision rather than the usual 8 weeks), or a full planning application where neither of the first two apply.
Getting this wrong in Falmouth is a common, expensive mistake – either building without permission you actually needed, or paying for a full application when a faster, cheaper route was genuinely available. Our desktop study establishes which situation actually applies to your project before you commit to anything.
Every Falmouth project gets a proper desktop study first, checking permitted development limits, Prior Approval eligibility, and any local restrictions specific to your property before we recommend anything.

How We Help in Falmouth
Every Falmouth enquiry starts with our free desktop study – checking your property against permitted development limits, conservation area or listed building status, and whether Prior Approval genuinely applies to your specific extension design.
From that assessment, we tell you plainly which route applies to Falmouth: nothing at all, the faster Prior Approval process, or a full planning application – and we prepare whichever one genuinely applies.
Where an application is genuinely needed for your Falmouth project, we keep you posted throughout and take on any council queries ourselves, so your extension keeps moving rather than stalling.
The Honest Answer For Falmouth Extensions
Assuming the wrong thing about your Falmouth extension – permission needed when it isn’t, or not needed when it genuinely is – is a costly mistake. Our desktop study replaces assumption with an actual, specific answer for your property.
Every Falmouth assessment is built around genuine accuracy, not assumption – because recommending an unnecessary application wastes your money just as much as missing one you actually needed.
Extension rules in Falmouth genuinely can involve a mix – part of a project under permitted development, another element needing full permission. We untangle exactly which parts of your specific project fall where, rather than treating the whole thing as one blanket answer.

House Extension Planning Permission FAQs for Falmouth
How big can my Falmouth extension be without planning permission?
Standard single-storey rear extensions can usually go up to 3 metres (terraced/semi-detached) or 4 metres (detached) without planning permission, with larger extensions up to 6-8 metres possible under the Prior Approval route – your desktop study confirms exactly what applies to your Falmouth property.
What is Prior Approval and does my Falmouth extension qualify?
Yes, Prior Approval typically takes 42 days rather than 8 weeks, and applies specifically to larger single-storey rear extensions – we check whether it’s genuinely available for your Falmouth project.
Are permitted development rights different in Falmouth conservation areas?
Yes – conservation area status in Falmouth typically removes some permitted development rights, particularly for side extensions and cladding, meaning full planning permission is more often required.
Does a previous extension affect what I can do now in Falmouth?
This is a genuinely common issue in Falmouth – if the property’s already been extended, remaining permitted development allowance may be reduced or gone entirely, which your desktop study checks.
Is it common for Falmouth projects to need a mix of routes?
It’s a genuinely common outcome for bigger Falmouth projects – our desktop study breaks down each element rather than giving one blanket answer for the whole extension.
Is the initial assessment free for Falmouth projects?
The desktop study itself is completely free for Falmouth projects – it’s the first step before any decision about applications or fees, so there’s no cost to finding out where you stand.
