Buckinghamshire Planning Advice Checker – Helpful, But Not the Full Picture
If you’re thinking about adding a garden room, you’ve probably asked the question:
“Do I need planning permission?”
Buckinghamshire Council has recently introduced a Planning Advice Checker to help answer that — and it’s a useful tool.
But while it’s a great starting point, it’s important to understand what it can and can’t tell you.
A Helpful First Step
The biggest challenge for most people at the start of a project is uncertainty.
This tool helps by giving you an initial idea of whether your garden room might need planning permission. It can highlight things like:
Whether your property is in a conservation area
If there are likely restrictions
Whether planning permission may be required
It’s quick, free, and easy to use — which is a big improvement on how things used to be.
But It’s Only a Guide
The key thing to remember is this:
The checker is guidance — not a decision.
It’s based entirely on the information you enter, and it doesn’t take into account things like:
Previous planning applications on your property
Local nuances or interpretations
Changes to permitted development rights
So while it’s helpful, it shouldn’t be relied on as a final answer.
Planning Isn’t Always Straightforward
In reality, planning isn’t black and white.
We see it all the time. Two very similar garden rooms can have completely different outcomes depending on:
The location of the property
Whether it’s in the Green Belt or a conservation area
Past planning history
How the project is presented
Some builds fall within permitted development but still raise questions. Others require planning purely because of where they’re located.
That’s why experience matters.
Where the Checker Works Well
Used in the right way, the tool is really valuable.
It helps you:
Get an early idea of what’s involved
Feel more confident before starting
Ask the right questions
And it means when you speak to us, you already have a basic understanding of where you stand.
What to Do Next
If you’re planning a garden room, our advice is simple:
Use the checker as a starting point
Don’t treat it as a final decision
If you’re unsure, get proper advice before you build
In some cases, even if planning isn’t required, it’s worth applying for a Lawful Development Certificate for peace of mind.
Final Thought
The Planning Advice Checker is a positive step and makes things more accessible.
But building a garden room isn’t just about ticking boxes — it’s about getting it right from the start.
If you’re unsure where you stand, we’re always happy to have a quick conversation and point you in the right direction.
