His remit is to increase the size of the riverside venue’s existing business and to develop brand awareness.
Lowther joins Altitude from running his own consultancy, whose portfolio included the Conkers Discovery Centre, the National Brewery Centre and Stonehenge Rising.
Prior to this he was managing director of Vinopolis in London.
Lowther said: "I am very excited about helping to oversee the continued growth of Altitude London. Not only are we looking to make it the premiere corporate and private events space in London, but to expand the concept throughout Europe."
