Interpretation of Part 4

The interpretation paragraph at the end of Part 4 of the GPDO is short, but its two definitions can matter when applying the temporary-use rights.

It defines what Part 4 means by a site and a war game. Those words should be read using the statutory definitions rather than their everyday meaning.

What does site mean in Part 4?

For Part 4, a site means the building and any land within its curtilage.

That matters because several Part 4 limits and conditions refer to the site as a whole rather than just the building or the precise area where a temporary activity takes place.

What does war game mean?

A war game is an enacted, mock or imaginary battle using weapons designed not to injure. The definition includes smoke bombs and guns or grenades that fire or spray paint or are otherwise used to mark participants.

It does not include military activities or training exercises organised by or with the authority of the Secretary of State for Defence.

The definition is particularly relevant to Class B, because Class B cannot be used on a site of special scientific interest for a war game.

Fees and appeals

The interpretation paragraph does not itself create an application procedure or fee. Any fee or appeal route depends on the particular Part 4 Class being used. Our planning fees page gives current charges and the appeals section explains the main challenge routes.

Relevant legislation

Paragraph F at the end of Schedule 2, Part 4 of the GPDO contains the statutory definitions.
