Building plans are needed to obtain a Lawful Development Certificate.
It’s also a good idea to obtain a Lawful Development Certificate. Although not compulsory, this can be a helpful document to have if, for example, you need to sell your property and prove that the building work you’ve done meets planning regulations.
You can apply online for a Lawful Development Certificate via the Planning Portal. You’ll need to submit drawings for your council to consider, and an application fee applies. You can usually expect to receive your certificate within 8-10 weeks. You’ll need:
Site Plan and Location Plan – So the council can find your property on a map and check what regs apply in your area.
Drawings of the existing building – Showing what the property looks like before work starts.
Drawings of the proposed building – Showing what the property will look like with the new extension.
