Sun Hung Kai Properties (SHKP) executive director Mike Wong says the 102-storey commercial tower at Kowloon Station will house the world's tallest hotel at the upper zone, creating a 'talking point'. The design is being finalised by New York-based architect Kohn Pedersen Fox, a firm which also is overseeing the design of Hongkong Land's Chater House in Central, Hang Lung Group's Plaza 66 in Shanghai and Mori Building's planned 460-metre World Financial Centre in Shanghai. Mr Wong said the new Kowloon Station tower design would provide efficient floor plates in the 480-metre, square building. The old design had a 100-metre architectural feature including a transparent atrium, which would have raised the structure's height to 580 metres. The 102-storey office-hotel tower is the phase seven development of the 12 million square foot Kowloon Station project, now named Union Square, at the southern tip of the West Kowloon reclamation area overlooking Victoria Harbour. SHKP has undertaken a large part of the project, including phases three, five, six and seven. The blueprint for phases five to seven has been revised in favour of taller buildings to create more open space. Phases five and six are combined to provide two 64-storey towers, instead of 45 storeys previously. One will include a hotel and serviced apartments while the other a hotel, serviced apartments and flats. Phase three, is a two twin-tower residential project. Amoy Properties is building three residential towers in phase four of Union Square. A consortium led by Wharf (Holdings) is developing the five-block Sorrento residential project, part of which is on pre-sale. Phase one, The Waterfront, was completed and developed by a Wing Tai Asia-led consortium. The developers are all in partnership with Mass Transit Railway Corp. Union Square, with 2.5 million sq ft of office space and nearly one million sq ft of shopping mall, is due for completion by 2007.
