Class BB – moveable structures for historic visitor attractions etc.
Class BB were introduced in early 2021 during the pandemic to allow for a temporary moveable structure (marquee probably) to be placed in the grounds of a historic visitor attraction or a listed pub, restaurant etc. The main purpose being to allow for additional space that is under cover.
Class BB was originally a temporary right to run until 1st January 2022, but was made permanent later in 2021. For non listed pubs and restaurants, then Class G of Part 2 applies giving similar benefits.
In order to allow the moveable structure to be erected a prior approval must be submitted to the local planning authority. This is a 56 day process.
The moveable structure must be no larger than 50% of the footprint of the building or 50 square metres, whichever is the smaller.
The property may erect the moveable structure for a period of up to 120 days in the year following a successful prior approval application to the local authority.
The full legislation for Class BB can be found below.
