Discover the 5 Essentials Every Homeowner Should Know About Planning Permission

Planning permission might sound complicated, but it doesn’t have to be. Whether you’re planning a kitchen extension, a loft conversion, or even a brand-new home, here are the essentials every homeowner should know before starting a project.

Discover the 5 Essentials Every Homeowner Should Know About Planning Permission

1. You might not need it

Not every project requires a full planning application. Many extensions, loft conversions and garden rooms fall under permitted development rights, meaning you can build without formal permission. To stay on the safe side, it’s always worth applying for a certificate of lawfulness to prove your project complies.

2. Conservation areas are different

If your home is listed or in a conservation area, you’ll need to follow tighter restrictions. Always seek professional advice before starting work to avoid costly mistakes.

3. The process is straightforward

If planning permission is needed, the steps are clear: your architect prepares the drawings, submits the application, and the council usually decides within eight weeks (though it can take longer). Most well-prepared schemes are approved, especially when they’ve been designed with local guidelines in mind.

4. Common reasons for refusal

Applications can be refused if a project is out of scale, impacts neighbours unfairly, or doesn’t respect the local character. These issues are often subjective, so understanding how the local council works is invaluable. At HPA, we’ve been working closely with local councils for more than 25 years, which helps us anticipate and avoid potential pitfalls.

5. An architect makes it easier

From navigating complex rules to dealing directly with planners, an architect smooths the whole process leaving you free to focus on the exciting part - watching your vision take shape.
