House Extension Planning Permission in
Lyme Regis

Extension rules in Lyme Regis 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 Lyme Regis project.

The Real Picture For Lyme Regis Extensions

There are genuinely three different routes an extension in Lyme Regis 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 Lyme Regis 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.

Rather than assuming permitted development applies or automatically preparing a full application, we start every Lyme Regis enquiry with a genuine assessment of what your specific project actually requires.

How We Help in Lyme Regis

For Lyme Regis 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 Lyme Regis 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 Lyme Regis project, we keep you posted throughout and take on any council queries ourselves, so your extension keeps moving rather than stalling.

Why Lyme Regis Homeowners Start With A Desktop Study

Assuming the wrong thing about your Lyme Regis 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 Lyme Regis 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.

We’d rather give you the complete, accurate picture of your Lyme Regis 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 Lyme Regis

What are the permitted development limits for an extension in Lyme Regis?

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 Lyme Regis property.

What is Prior Approval and does my Lyme Regis 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 Lyme Regis project.

Does living in a conservation area affect my Lyme Regis extension?

Yes – conservation area status in Lyme Regis 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 Lyme Regis?

This is a genuinely common issue in Lyme Regis – if the property’s already been extended, remaining permitted development allowance may be reduced or gone entirely, which your desktop study checks.

Can part of my Lyme Regis extension be permitted development and part need permission?

It’s a genuinely common outcome for bigger Lyme Regis projects – our desktop study breaks down each element rather than giving one blanket answer for the whole extension.

Is the initial assessment free for Lyme Regis projects?

Yes, the desktop study is free for Lyme Regis enquiries – you’ll know exactly what your project needs before committing to anything further.
