House Extension Planning Permission in
Chippenham
Extension rules in Chippenham 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 Chippenham project.

Permitted development rules for extensions are genuinely more generous than most people in Chippenham expect, but they’re also easy to misjudge. A single-storey rear extension within the standard depth limits (usually 3-4 metres, or up to 6-8 metres under Prior Approval) can often proceed without a full planning application – but ‘often’ isn’t ‘always’, and getting it wrong means enforcement action, not just a delay.
Side extensions, anything affecting a conservation area, listed buildings, and properties where permitted development rights have already been used or restricted by condition all change the picture in Chippenham. Our free desktop study checks your specific circumstances rather than assuming the general rule applies.
Our free desktop study for Chippenham projects checks your property’s planning history, current permitted development allowance, and any local restrictions before recommending a route – so you know exactly what’s needed before spending anything further.

How We Help in Chippenham
For Chippenham 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 Chippenham 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 Chippenham project, we keep you posted throughout and take on any council queries ourselves, so your extension keeps moving rather than stalling.
Getting Chippenham Extensions Right From The Start
Assuming the wrong thing about your Chippenham 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.
We’d rather tell you honestly that your Chippenham extension doesn’t need planning permission at all than take a fee for an application that was never required. That honesty is the whole point of the desktop study.
Rather than a single yes-or-no verdict, we break down exactly what applies to each element of your Chippenham extension, since larger or more complex projects often genuinely mix permitted development with elements that need permission.

House Extension Planning Permission FAQs for Chippenham
What are the permitted development limits for an extension in Chippenham?
Limits vary by extension type and house style in Chippenham, which is exactly why a proper assessment matters more than a generic rule of thumb – your desktop study confirms your specific allowance.
Is Prior Approval faster than planning permission in Chippenham?
Prior Approval is a faster route (42 days rather than the usual 8 weeks) for larger single-storey rear extensions that exceed standard permitted development limits but stay within extended ones – your desktop study checks whether your Chippenham project qualifies.
Are permitted development rights different in Chippenham conservation areas?
Conservation area properties in Chippenham generally have reduced permitted development rights, which is exactly the kind of local factor our desktop study checks before recommending a route.
Does a previous extension affect what I can do now in Chippenham?
This is a genuinely common issue in Chippenham – 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 Chippenham projects to need a mix of routes?
It’s a genuinely common outcome for bigger Chippenham projects – our desktop study breaks down each element rather than giving one blanket answer for the whole extension.
How much does the desktop study cost for a Chippenham extension?
The desktop study itself is completely free for Chippenham projects – it’s the first step before any decision about applications or fees, so there’s no cost to finding out where you stand.
