General Permitted Development Order 2015

The new Town and Country Planning (General Permitted Development) (England) Order 2015 comes into force on 15th April 2015.

The Order replaces the Town and Country Planning (General Permitted Development) (England) Order 1995 and consolidates the various amendments which have been made to it since its original inception.

Under the 2015 Order permitted development rights under Schedule 3, such as the change of use of Office (B1(a)) to a use falling within Class C3 dwelling houses and the change of use of agricultural buildings to C3 dwellings have been reclassified under Class O and Q respectively (formally Class J and Class MB).

Key changes in relation to agricultural buildings to dwellinghouses are:

  • Amendment to the wording of the Order to confirm that the cumulative number of separate dwellinghouses allowed to be developed under Class Q within an established agricultural unit is 3
  • The development must be completed within a period of 3 years starting with the prior approval date.


The 2015 Order also introduces Class P where the change of use of a building and land within its curtilage from a use falling within Class B8 (storage or distribution centre) to a C3 dwelling house is permitted, subject to the relevant criteria.
