Permitted Development Changes

19th March 2018

Several amendments to the General Permitted Development Order come into effect on 6th April 2018. In summary, the changes are:

Classes P & PA: Change of Use from Class B8 or Class B1(c) to Residential

  • The permitted changes of use can no longer apply to part of a building only.
  • The temporary right under Class P to change from Class B8 to residential is extended until 10th June 2019; implementation to be within 3 years from the date that prior approval is granted.

Classes C, M, N & Q: Change of Use from Specified Uses to Retail (Class C) or Residential (Classes M, N & M)

  • It is clarified that permitted building operations associated with these changes of use cannot be carried out independently, and they must be specified in the prior approval application.

Class Q: Change of Use from Agriculture to Residential

  • The maximum number of units that can be created is increased from 3 to 5 (including any previous conversions under Class Q).
  • There are new definitions of ‘smaller’ (up to 100m²) and ‘larger’ (100m² – 465m²) dwellings, with the floor space limitation for larger ones increased from 450m² to 465m².
  • Up to 3 ‘larger’ dwellings and 5 ‘smaller’ dwellings are permitted, with a maximum cumulative floor area of 465m², although no more than 5 units in total can be created (including any previous Class Q developments).
  • The prior approval application must specify:
    • a) how many larger or smaller dwellings are proposed;
    • b) whether any previous development has taken place on the agricultural unit under Class Q; and
    • c) the number of smaller and larger dwellings previously developed (if any).

Class A of Part 6: Agricultural Buildings

  • The floorspace limit of 465m² is increased to 1000m², while the maximum increase in the floor area of any building is raised from 10% to 20%, (although several other restrictions still apply).

Other changes:

  • The definition of ‘military explosive storage area’, ‘railway undertakers’ and ‘transport undertakers’ is amended.
  • Prior approval applications called-in by the Secretary of State will not be subject to a fixed time limit for determination.
