It’s also worth noting that under this Class, permitted development allows reasonable construction operations, but only within the existing structure. New internal walls? Fine. New doors and windows? You’re good to go. But if you want to simply knock down flimsy elements and essentially build a residence from scratch, then this won’t be covered.
What's more, you’re barn conversion will also be excluded from the scheme should you reside in a conservation area or national park.
Lawful Development Certificate
Think you’re out of the planning woods? Think again.
While you might not need a full planning application, you will need to obtain a lawful development certificate. This is vital for a barn conversion, and failure to do so could result in heavy fines or even the demolition of your project.
To prove your build is legal, you’ll need to give Prior Notification to your local authority. This will involve submitting your proposed designs and having them reviewed in order to make sure you’re within your permitted development rights.
Other considerations will be…
- Noise impact
- Flood risk
- And ‘whether the location or siting of the building makes it otherwise impractical or undesirable for the building to change from agricultural use to residential use.’
Including the wait for your project to be validated and assigned a planning officer, this stage can take anywhere between 8-13 weeks. To give yourself the best chance of first-time approval, we recommend getting an architect to handle the process on your behalf.
Building regulations are a set of statutory requirements that all buildings must meet in order to create a safe and healthy environment to inhabit.
They cover everything from the structure, thermal performance, sound-proofing, drainage, all the way to fire safety - to name just a few!
To ensure your project is in line with UK building regulations, you must commission a set of technical drawings of your proposed build, demonstrating all legal requirements have been met, before submitting this to either your local building control or by hiring a private approved inspector.
The scope of work covered by this stage means you’ll need more than one professional on board to prepare your application. For a barn conversion, this will typically include…
- A structural engineer
- An architect
- A CCTV surveyor
- A party wall surveyor
- An approved inspector

Your budget will depend on a lot of different factors, such as…
- State of the existing structure
- Complexity of design
- Project size
- Professionals hired
- Location of your project
- Quality of materials
For smaller barns, you’ll likely need a budget of £80 - 100,000. For large scale projects, this could go up to £250,000.
