Not every home project in Doncaster needs full planning permission. Some changes fall under permitted development. But how do you know the difference?
At PBM Plans, we help you avoid confusion. Whether your project qualifies as permitted development or needs a planning application, we guide you through the process, provide accurate drawings, and help get the right approval in place.
What Does Permitted Development Mean?
Permitted development allows you to carry out certain types of work without needing full planning permission. These rights are set by national law, not your local council.
They apply to most houses in Doncaster, but there are limits. Flats, listed buildings, and homes in some restricted areas may not qualify.
What Kind of Work Is Usually Covered?
Many common home improvements fall under permitted development. For example:
- Single-storey rear extensions
You can often extend up to 3 metres for a terraced house or 4 metres for a detached one. - Loft conversions
You may add up to 40m² (terraced) or 50m² (semi or detached), as long as it doesn’t change the roofline at the front. - Garage conversions
Internal work to change a garage into a room often doesn’t need full permission. - Outbuildings and garden rooms
These can be allowed if they’re single storey, under 2.5 metres high (near boundaries), and not for residential use. - Porches
Small porches under 3m² in area and 3 metres in height are usually permitted.
Every site is different. We check your exact layout and plans to confirm if your idea fits the permitted rules.
What Are the Rules and Limits?
Even under permitted development, there are strict conditions:
- You can’t cover more than 50% of your garden with extensions or outbuildings
- Materials must be similar to the existing house
- Extensions must not face the highway (for side and some front extensions)
- Dormers must not extend beyond the roof slope at the front
- Side extensions have a maximum height and width limit
- Height limits vary depending on proximity to boundaries
If any of these are exceeded, you’ll need full planning permission. We check all this for you before any drawings are done.
What Is a Lawful Development Certificate?
Even if your project is permitted, it’s still wise to get written proof. That’s where a Lawful Development Certificate (LDC) comes in.
This is confirmation from Doncaster Council that your plans are legal and don’t need planning permission. It’s not required, but it protects you when:
- You sell or remortgage the property
- You want written proof for future planning
- There’s a dispute with a neighbour or builder
PBM Plans can prepare and submit LDC applications. We include all required drawings and forms to make the process smooth.
When Do You Need Full Planning Permission?
There are many cases where permitted development doesn’t apply. You’ll need a full planning application if:
- The extension is too large or too high
- The work faces a public highway
- The property is in a conservation area
- The building is listed
- You want to divide the house into separate homes
- The council has removed your permitted rights (known as an Article 4 direction)
We check all these details when you contact us. If full permission is required, we prepare the drawings and submit the application for you.
How Do You Check for Restrictions?
Some properties in Doncaster have extra planning rules. These can affect whether permitted development applies. We check for:
- Conservation areas
Even small changes often need permission in these zones. - Article 4 directions
These remove permitted development rights in specific streets or estates. - Listed building status
Any change, inside or out, needs listed building consent and planning permission. - Previous extensions
If the property has already been extended, you might have used up your allowance.
PBM Plans handles all checks for you. You’ll know from the start whether you need permission or not.
How PBM Plans Helps with Both Options
We’re not here to sell you services you don’t need. If your extension qualifies for permitted development, we’ll tell you. If it needs full planning, we’ll handle that too.
We help by:
- Visiting your home for a measured survey
- Confirming whether planning is needed or not
- Producing drawings that meet all council standards
- Submitting applications for Lawful Development Certificates or planning permission
- Liaising with Doncaster Council on your behalf
Most projects we handle in Doncaster fall into one of these two routes. Either way, we make it simple, affordable, and stress-free.
Permitted development saves you time and paperwork—but only if your project qualifies. If not, planning permission is the way forward. The key is knowing the rules and preparing the right documents.
PBM Plans helps you work out which route applies. We produce the drawings and submit the applications that get you approved, whether it’s a garden room or a full rear extension.
