If you’re planning a house extension in Bury, one of the first questions you’ll likely ask is: “Do I need planning permission?” The answer depends on the type, size, and design of your extension, as well as the specific planning rules set by Bury Council. Getting this right is essential, as carrying out work without the correct approval could lead to enforcement action or even the requirement to undo the work.
In this guide, we’ll explain when you’ll need planning permission, when permitted development rights may apply, and how to make sure your project in Bury runs smoothly.
What Are Permitted Development Rights?
Permitted development rights are national rules that allow homeowners to extend their properties without applying for full planning permission. These rights are designed to make small to medium-sized home improvements quicker and easier.
However, there are conditions and limitations, and in some cases, Bury Council may have removed or restricted these rights (for example, if your property is in a conservation area).
When You Don’t Need Planning Permission in Bury
You may not need planning permission if your extension falls within permitted development limits. Some of the key rules include:
- Single-storey rear extensions can be built up to 3 metres deep for terraced or semi-detached houses, and 4 metres deep for detached houses.
- With the Neighbour Consultation Scheme, this can be extended to 6 metres for semi-detached and 8 metres for detached homes, subject to approval.
- The maximum height of a single-storey extension is 4 metres.
- Two-storey extensions must be at the rear of the house, no more than 3 metres deep, and at least 7 metres away from the rear boundary.
- Extensions cannot cover more than 50% of the land around your original house (as it was first built or stood in 1948).
- Materials must be similar in appearance to the existing house.
When Planning Permission Is Required in Bury
You’ll need to apply for planning permission if your project does not fall within permitted development rules. Common examples include:
- Extensions higher than the highest part of the existing roof.
- Building forward of the principal elevation (the front of the house facing the road).
- Side extensions that are more than one storey, or more than half the width of the original house.
- Extensions in conservation areas or on listed buildings (these often require special consent).
- Using significantly different materials that alter the look of the property.
If your house is a flat, maisonette, or converted property, permitted development rights usually don’t apply, meaning planning permission is required.
How to Check With Bury Council
Before starting any extension work, it’s important to check with Bury Council’s planning department. They can confirm whether your project qualifies under permitted development or requires a full application.
You can:
- Use the Planning Portal (the government’s online planning service).
- Contact Bury Council’s planning team directly.
- Apply for a Lawful Development Certificate (LDC) – not mandatory, but it provides legal proof that your extension doesn’t require planning permission.
Building Regulations Still Apply
Even if you don’t need planning permission, your extension must comply with Building Regulations. These cover structural safety, fire safety, energy efficiency, drainage, and ventilation. You’ll need to submit your plans to Building Control and arrange inspections during construction.
Key Considerations Before Extending in Bury
When planning your house extension, it’s worth thinking beyond just planning permission. Consider:
- Neighbours – Talk to them early to avoid disputes. Larger extensions under the Neighbour Consultation Scheme require their feedback.
- Design & Materials – Choose a style that complements your home and neighbourhood.
- Budget & Hidden Costs – Factor in planning application fees, Building Control charges
