The Town and Country Planning (General Permitted Development) (England) Order 2015 came into force on the 15 April 2015 and has been amended as of April 2018. The Order has updated and reclassified the Permitted Development Rights under Schedule 2 Part 3 (i.e. Changes of Use).
Class Q (formerly class MB) allows for development consisting of:- A change of use of a building and any land within its curtilage from use as an agricultural building to a use falling within Use Class C3 (dwelling houses); and Building operations reasonably necessary to convert the building to a use falling within Class C3.
For the permitted development rights to apply, certain criteria need to be met.
Although the regulations allow for residential conversions in principle, there is a prior notification procedure to be undertaken with the Local Planning Authority (LPA).
