Grosvenor – co-owner and asset manager of Liverpool One – and Gravity Active Entertainment have announced plans for a £10m leisure development.

Plans comprise a 100,000 sq ft space at the retail, leisure and entertainment destination, which will house an evolution of Gravity Southside in Wandsworth on the two upper floors of the former Debenhams site.

Due to open in Q4 this year, the venue will be the first of Gravity’s to feature a rooftop space. Activities within the venue will include an e-karting experience, bowling, urban golf and there will be a modern F&B offering with a bar concept and live entertainment.

The Liverpool One venue will become Gravity’s flagship site within its 18-strong portfolio in the UK.

Michael Harrison, co-founder and chief growth officer at Gravity, commented: “This is our biggest investment yet and we are delighted to be collaborating with Grosvenor, at a destination that has continued to perform positively despite the recent market challenges.

“As a business, we are getting stronger all the time and we have no doubt that we will control one million square feet of the high street within the next two years.”

Gravity is targeted revenue of £20m in 2022.
