Planning permission is asking for permission to do a certain piece of building work, whether it’s an extension to your house or a new superstore for a major developer. It will either be granted, subject to certain conditions, or refused. The government has set out its rules on determining planning applications called the National Planning Policy Framework. Local authorities or planning development control have their own local plans. You can find your LPA (Local Planning Authority) on the planning portal and then search for the local development plan. This will give you full details on specific areas and any forthcoming plans or restrictions.
