The second phase of the centre, located on an artificial island, was constructed from 1994 to 1997, and features a bird-like rooftop (also referred to as a turtle by some critics[who?]). The project took only 48 months from reclamation to completion. The main constructor of the extension was a joint venture named Hip Hing Construction Co Ltd Dragages et Travaux Publics. Originally, Phase Two was connected to Phase One with an atrium link (a sky bridge), and to Convention Road with two road bridges, but now the two phases are connected by an expanded exhibition hall.
HKCEC made a second expansion during 2006-2009. Upon completion, the HK$1.4 billion expansion added 19,400 sqm to the HKCEC, bringing the total exhibition space to nearly 83,000 sqm and total rentable function space to over 92,000 sqm.
