House Extension Planning Permission in
Llantwit Major
Extension rules in Llantwit Major aren’t as simple as yes-or-no on planning permission. Depending on size, position, and whether your property sits in a conservation area, your project could be permitted development, need Prior Approval, need full permission, or involve a genuine mix of all three. We work out exactly which for your specific Llantwit Major project.

There are genuinely three different routes an extension in Llantwit Major 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 Llantwit Major 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 Llantwit Major 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 Llantwit Major
For Llantwit Major properties, we start by working out the actual picture – existing extensions, conservation status, and exactly what your proposed extension would involve – before recommending anything.
Once that’s clear, your Llantwit Major project gets exactly what it needs, whether that’s confirmation permitted development already covers it, a Prior Approval submission, or a full application prepared to what this specific council expects.
Where an application is genuinely needed for your Llantwit Major project, we keep you posted throughout and take on any council queries ourselves, so your extension keeps moving rather than stalling.
Getting Llantwit Major Extensions Right From The Start
Assuming the wrong thing about your Llantwit Major 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.
Our advice on Llantwit Major extensions reflects what your specific project genuinely needs, not what generates the most billable work. If permitted development covers you, we’ll say so plainly.
We’d rather give you the complete, accurate picture of your Llantwit Major project upfront – including where it’s a genuine mix of routes – than a simplified answer that misses something important.

House Extension Planning Permission FAQs for Llantwit Major
What are the permitted development limits for an extension in Llantwit Major?
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 Llantwit Major property.
What is Prior Approval and does my Llantwit Major 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 Llantwit Major project.
Does living in a conservation area affect my Llantwit Major extension?
Conservation area properties in Llantwit Major generally have reduced permitted development rights, which is exactly the kind of local factor our desktop study checks before recommending a route.
Can I still use permitted development if my Llantwit Major house has been extended before?
This is a genuinely common issue in Llantwit Major – 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 Llantwit Major projects to need a mix of routes?
It’s a genuinely common outcome for bigger Llantwit Major projects – our desktop study breaks down each element rather than giving one blanket answer for the whole extension.
