Planning permission in Trafford isn't a single rulebook. It's a layered set of national rules, local policies, and property-specific designations — and the combination that applies to your home is almost impossible to know without checking. Most homeowners assume they're fine and find out too late that they weren't. WhatCanIBuild exists precisely for this moment: before you commit to anything.
The short version
- Trafford has conservation areas, Green Belt land, and Article 4 directions that restrict what's normally permitted
- Rules that apply to your neighbour's house may not apply to yours
- Getting it wrong can mean enforcement action, not just a refused application
Conservation areas don't behave the way you'd expect
Altrincham town centre, Hale, and Bowdon all have conservation area status — but so do pockets of streets that most residents don't even know are designated. If your property sits within one, work that would be completely fine elsewhere in Trafford can require full planning permission. And it's not just listed buildings. Ordinary terraced houses, semis, even garages can be caught.
Most homeowners in these areas don't realise the designation exists until something goes wrong. The question isn't whether you've heard of your conservation area — it's whether you know exactly what it restricts on your specific property.
Article 4 directions remove rights you thought you had
Trafford Council can — and does — remove permitted development rights through something called an Article 4 direction. These aren't publicised widely. They can apply to an entire neighbourhood or just a handful of streets, and they mean that work you assumed was permitted suddenly requires a full application.
The tricky part: you probably don't know if one applies to your address. It won't show up in a general search. It won't be on your deeds. And your neighbour being able to do something doesn't mean you can.
Worth knowing
Permitted development rights also don't apply to flats or maisonettes. If your home was converted at any point, the rules you think apply may not.
Green Belt land to the south changes everything
Trafford's Green Belt covers significant areas to the south of the borough — including land around Dunham Massey. Green Belt designation isn't just about countryside. Properties on or near the boundary can face much stricter scrutiny on extensions, outbuildings, and changes of use than homes elsewhere in the borough.
The boundary isn't always obvious from the street. It doesn't follow neat postcode lines. Whether your garden sits inside or outside it can be the difference between a straightforward permitted development claim and a full application with an uncertain outcome.
What's been refused nearby tells you more than the rules do
Even if you understand what the rules say, that's not the same as knowing how Trafford applies them. Two seemingly identical extensions on the same street can have very different outcomes depending on the officer, the specific constraints on that plot, and what's been approved or refused nearby.
That's the gap most homeowners fall into — they know they're in a conservation area, but they don't know what that actually means for their project, on their street, with their property's specific history. WhatCanIBuild surfaces what's actually been approved and refused for similar projects near your address — not just what the rules say in theory, but what's happened in practice.
Householder applications in Trafford carry a £258 fee and an 8-week decision window. That's before any back-and-forth, redesigns, or appeals. The best way to avoid spending that time and money on a project that was always going to struggle is to understand your odds before you start — not after. WhatCanIBuild gives you that picture based on your actual address, not a general guide.
