Simon Ryan, who appeared on the first series of the ITV programme, said it was at one point “a Mayfair club in Essex”.
“Going to Sugar Hut, you didn’t know who you were going to bump into,” he told Essex.
“They had some very famous clientele there. It was central in a lot of drama and storylines of TOWIE.”
Ryan said Norcross and his son, Kirk, built a “fantastic experience” for punters wanting a night out.
“You just didn’t know who you’d see in there and it was a great vibe,” he added.
He said it would be “the end of an era” if the building did not continue as a nightclub.
When the building last changed hands, it was bought in 2012 for £1.3m by Karma Assets Limited.
According to Companies House, the Essex company is run by managing director Zivile Milusauskaite, and the firm still owns Sugar Hut.
