House Extension Planning Permission in
Dereham (Norfolk)
Extension rules in Dereham 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 Dereham project.

Dereham’s planning authority, like every council, has to work within national permitted development rules, but local factors – conservation area status, Article 4 directions, existing extensions on the property – all affect what’s actually available to you here specifically.
A generic online guide can tell you the national rules, but it can’t tell you whether your specific Dereham property still has its permitted development rights intact, or whether a previous owner’s extension has already used up the allowance. That’s exactly what our desktop study establishes.
Our free desktop study for Dereham 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 Dereham (Norfolk)
Every Dereham enquiry gets a genuine assessment, not assumption – checking permitted development limits against your specific proposal, and whether your property’s history affects what’s still available to you.
Once that’s clear, we handle exactly what your Dereham project needs, prepared properly whether that’s a straightforward Prior Approval submission or a full application.
Where an application is genuinely needed for your Dereham project, we keep you posted throughout and take on any council queries ourselves, so your extension keeps moving rather than stalling.
Getting Dereham Extensions Right From The Start
Every Dereham enquiry gets a genuine, property-specific assessment rather than a generic answer based on typical extension sizes – because typical isn’t always what applies to your actual project.
Every Dereham 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.
We’d rather give you the complete, accurate picture of your Dereham 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 Dereham
What are the permitted development limits for an extension in Dereham?
Limits vary by extension type and house style in Dereham, which is exactly why a proper assessment matters more than a generic rule of thumb – your desktop study confirms your specific allowance.
What is Prior Approval and does my Dereham 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 Dereham project.
Are permitted development rights different in Dereham conservation areas?
Yes – conservation area status in Dereham 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 Dereham?
This is a genuinely common issue in Dereham – 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 Dereham projects to need a mix of routes?
Yes, this happens regularly with larger or more complex Dereham projects – one element might fall under permitted development while another genuinely needs full permission, and we identify exactly which is which.
How much does the desktop study cost for a Dereham extension?
The desktop study itself is completely free for Dereham projects – it’s the first step before any decision about applications or fees, so there’s no cost to finding out where you stand.
