The preferred occupier for the Olympic media centre, iCITY, says it has prelet 47% of the 1m sq ft site.
Speaking yesterday at an Olympic legacy press conference in London, the company's chief executive Gavin Poole said iCITY will announce new tenants in the autumn and expects tenants to move in by 2014.
While a significant portion of the prelets is taken up by Infinity's data centre and Loughborough University, Poole said his company had been in positive discussions with several businesses for further space.
In an interview with EGTV, Poole said talks had been held with business incubators, post production companies and Hackney Community College.
"We have TV studios and companies - a major channel looking at coming to relocate," he added.
"We have a robust business plan. That's what won us the bid. We are 47% prelet already and we are looking at taking it from 1m to 1.5m sq ft... because we are so confident that we are going to fill this space."
