Planning
Permission
"Do I need planning permission?"
This is one of the most commonly asked questions from our clients, and for good reason.
Requiring Planning Permission from your local council will add additional fees to your project and take time.
Local councils have a lead time of seven weeks to return
a decision, but due to a backlog from the pandemic, 2023 has seen some councils take up to 3 - 4 months
to return a decision.
Luckily not all projects require
full Planning Permission...
Permitted
Development
Depending on the size and scale of the project, many householder projects such as extensions, garage and loft conversions fall under a clause called Permitted Development (P.D) and may not require planning permission.
"What can I build under Permitted Development?"

Any extension must not result in more than half the garden being covered and must not go forward of the building line of the original dwelling.
