Part 4: Temporary buildings and uses
You might not want a permanent change of use and instead be looking for a temporary change. The GPDO has you covered in Schedule 2, Part 4
This covers items ranging from buildings to support construction, temporary campsites, car boot sales, schools, marquees in listed buildings, filmmaking and so much more.
Class B is probable the most common used, which is the use of land for any purpose for up to 28 days a year. However as with any temporary use, the devil is in the detail. use any of the links below to go to the relevant pages.
Whilst a change of use might not need permission, any external building work associated with a change of use may still require planning permission. The table below simplifies the complex legislation and should be read as a guide only, and in conjunction with the additional comments and restrictions below. Where we have articles on this Planning Geek website we have added direct links. P4/Class…. refers to the various sections within the GPDO – see this page for all those sections.
If applications are required or you need clarification, Planning Geek can assist. Reach out to us via this page.
