The legislation creates a new class, JA of the GPDO to allow proposals for the conversion of shops and other high street uses to B1 offices under the prior approval process. Class M already allows retail and sui generis uses to be converted to residential without the need for planning permission, but the new regulations would allow takeaways to also be converted to housing.
The regulations also makes permanent the existing temporary right to enlarge a dwellinghouse by up to 8 metres in the case of a detached dwellinghouse or by 6 metres in the case of any other dwellinghouse removing the time limiting date of 30th May 2019, as well as conditions which required development to be completed by that date.
