CITIBANK has confirmed it is negotiating to lease office space at the twin-tower Gateway complex developed by Wharf (Holdings) in Tsim Sha Tsui. A Citibank spokesman said the bank had approached the agents about a possible lease, but it was not the only property it was considering. She would not comment further. The bank is said to be considering leasing about 60,000 sq ft of space at Gateway. If the deal goes through, Citibank would be the second-largest tenant in the project. Hongkong Bank, the largest tenant, has leased 107,000 sq ft of space at Gateway, which has a total floor area of about 1.2 million sq ft. Wharf and Richard Ellis, joint leasing agents of Gateway, would not comment on the negotiation with Citibank. Chris Reilly, associate director of Richard Ellis, said nearly 80 per cent of Gateway was leased, with about 50 tenants in occupation. Despite a traditionally quiet period in December, he said there were still many inquiries for Gateway. He cited the building's location and facilities as generating the interest. In a joint deal with Great Eagle Holdings and Kerry Holdings, Citibank recently bought back for its own use 53,000 sq ft of space at Citibank Plaza in Admiralty, adding to 200,000 sq ft already owned and occupied by the bank.
