Planning permission in Bury isn't a simple yes or no — and most homeowners only find out the hard way. The rules that apply to your neighbour's extension might not apply to yours, even if you live on the same street. WhatCanIBuild was built to cut through exactly this kind of complexity, using your actual address rather than general rules.
The short version
- Whether you need permission depends on your specific property, not just the type of project
- Bury has Green Belt, conservation areas, and heritage corridors that change the rules significantly
- The householder application fee in Bury is £258, with a typical decision time of 8 weeks — but getting there starts with knowing whether you need to apply at all
Bury isn't a single set of rules
Bury Metropolitan Borough Council covers a wide area — from the M25 and M26 postcodes in the south through to BL0 in the north. That geographic spread matters, because the planning constraints across that territory are anything but uniform.
Green Belt land covers significant portions of Bury's northern areas. Conservation areas exist in Ramsbottom, Tottington, and parts of Prestwich. The East Lancashire Railway corridor brings its own heritage considerations. Each of these layers can fundamentally change what you're allowed to do — and whether permitted development rights even apply to your property at all.
Most homeowners don't realise that permitted development — the rules that let you build without applying — can be removed entirely for certain properties. Article 4 directions, listed building status, and location within a conservation area can all strip away rights that your neighbour two streets over still has.
Don't assume your neighbour's project sets a precedent
Just because someone nearby built an extension or added a dormer without planning permission doesn't mean you can. Their property's constraint profile may be completely different from yours.
The things that quietly catch people out
There are categories of complication that trip people up before they've even drawn up plans. Conservation area boundaries are one — they don't follow obvious lines, and being just inside one changes everything. Flood zones are another. So is the specific history of your property: what's already been built, what conditions were attached to previous permissions, and whether any of those conditions are still live.
Then there's Green Belt. If your property sits within or adjacent to Bury's Green Belt, the threshold for what counts as acceptable development shifts considerably. It's not that nothing can be done — it's that the bar is different, and most homeowners don't know which side of that bar their project falls on.
The best way to understand what actually applies to your property — not properties like yours, but yours specifically — is to use WhatCanIBuild, which checks your address against the full picture of local constraints and shows you what's been approved and refused for similar projects nearby.
What your address actually tells you
Knowing you're in a conservation area is one thing. Knowing what that means for a rear extension on your particular house, on your particular street, given what Bury Council has approved and refused for similar applications recently — that's something different entirely.
That gap between knowing a constraint exists and knowing what it means for your project is where most planning mistakes happen. The £258 application fee and 8-week decision window are the least of your worries if you've already started work assuming you didn't need permission.
WhatCanIBuild shows you the approval odds for your specific project type in your area, what similar applications on nearby streets have looked like, and how your property's combination of constraints actually affects your chances — the kind of detail this article deliberately can't give you.
These rules vary by property
