House Extension Pre Planning Application Assessment Report by Draw Plans
If you’re planning a house extension, it’s essential to check whether your project needs planning permission. At Draw Plans, we create clear and accurate House Extension Planning Reports to help you understand your chances of success and avoid costly mistakes.
Whether you’re building a rear extension, a side return, or a double storey extension, we provide expert advice tailored to your home and local planning rules.
Why You Need a House Extension Planning Report
Many extensions fall under Permitted Development, but not all. If you’re unsure about your rights, if your property is in a conservation area, or you want to maximise your extension size, our report gives you clarity.
Our planning reports are ideal for:
-
Rear extensions that push the limits of depth or height
-
Single storey extensions near boundaries or outbuildings
-
Double storey extensions that change the streetscape or overlook neighbours
-
Homes in conservation areas or affected by Article 4 directions
-
Flats and maisonettes (which always require planning permission)
What We Include in Your Extension Planning Report
Your customised house extension planning permission report covers:
-
Planning constraints (Article 4, flood risk, conservation zone, listed status)
-
Assessment against Permitted Development rights
-
Local precedent – recent approvals and refusals in your street
-
Clear advice on whether to proceed with a Lawful Development Certificate or a full Planning Application
-
Recommendations for improving your chance of approval
Pricing – Reports from £395 + VAT
