Details are still very much up in the air, but per the Telegraph:

The BBC is to turn shows such as Doctor Who, Top Gear and Sherlock into theme park attractions in a British rival to Disneyland.

BBC Worldwide, the corporation's commercial arm, has signed a landmark deal with the company behind a £2bn Paramount Pictures resort planned for Kent.

[..]

The resort is scheduled to open in Swanscombe, Kent in 2020 and hopes to 15 million visitors per year. The south-east of England location was chosen to position the park as a rival to Disneyland Paris.

The BBC said it could not confirm which shows will be developed into rides as negotiations are at an early stage, but it is all but certain that Doctor Who – with its potential for Tardis simulators and Dalek battles – will be the star attraction.

I hope they display some of the guys' creations. Beyond that,what could the Top Gear attractions be?
