Prior Approval is a formal submission to your local planning authority and the purpose of it is to seek assent that specified parts of development are acceptable, before work can commence. There are different types of prior approval which require various levels of detail before a Council will assess a proposal. Depending on what you are seeking prior approval for you could be required to submit information on a wide variety of aspects of the proposal, including design and external appearance, the transports impacts of the development and flooding information.
To find out more information on this speak to your local planning authority or get in touch with Ashleigh Clarke Architects who will be happy to help.
