Permitted development rights (Class Q) allow for the conversion of some existing agricultural buildings to residential use without the need for full planning permission. Various conditions and limitations apply including a requirement to seek a determination from the local planning authority on whether prior approval will be required in respect of the following matters:
- transport and highways impacts
- noise impacts
- contamination and flooding risks
- location or siting of the building
- the design or external appearance of the building (where building operations are required)
The relevant legislation is contained in Class Q of Schedule 2 Part 3 of the Town and Country Planning (General Permitted Development) (England) Order 2015 as amended.
