The O2 Arena in London is set to get a trampoline park, alongside a new cinema and shopping centre.
The O2 is to increase its footprint by 110,000sq.ft, with the additions set to deliver an extra four to five million visitors per annum, according to operator AEG.
The new development, a joint venture between AEG Europe and Crosstree Real Estate Partners, will break ground in late September.
The trampoline park, managed by Oxygen Freejumping, is to include a Bear Grylls Fitness obstacle course, a trampolining school, and parties and facilities for autistic-friendly and disability sessions.
They join an under-construction shopping centre, due to open in the final months of 2018.
