Expert architects maximizing your property's potential under PDR, saving you time and money.
Build Without Planning Permission.
Permitted Development Rights (PDR) are a national grant of planning permission allowing certain building works without a planning application. This can save months of time and thousands in fees.
As expert architects, we know exactly what's possible under PDR and how to maximize your property's potential within the rules. We ensure full compliance while achieving the space you need.
Even under PDR, you need Building Regulations approval and possibly a Lawful Development Certificate. We handle everything, ensuring your project is legal and properly documented.

- •No planning application needed
- •Save 3-4 months waiting time
- •No planning fees (save £200-500)
- •No risk of planning refusal
