Henderson Land Development has secured government approval to increase the size of a hotel development in Kwun Tong. The developer will build a maximum of 598 rooms in the 33-storey hotel, at the junction of How Ming Street and Wai Yip Street, compared with the 555 rooms allowed for in a previous blueprint. The revised plan, approved by the Town Planning Board yesterday, will provide a total floor area of 235,300 square feet on a 19,050 sqft site. The project forms part of the group's ambitious expansion in the hotel industry through the conversion of land use for industrial properties in urban areas. Since last year, Henderson has received approval for a number of such projects, involving a total of 5,500 rooms in locations that include Kwun Tong, San Po Kong, Cheung Sha Wan and Aberdeen. Henderson Land vice-chairman Colin Lam Ko-yin said earlier that the group had a number of sites with the potential for redevelopment into hotels, providing a total of 10,000 rooms. In the past two years, developers have anxiously sought government approval to redevelop industrial properties into hotels in anticipation of a mainland tourist boom following Beijing's easing of restrictions on individual travellers last year. The Town Planning Board has approved 40 applications for hotel developments since January last year - a potential 19,000 rooms. Analysts said many of the redevelopments would be three-star hotels in non-traditional tourist districts. Other active players include Sun Hung Kai Properties and Chinachem Group. According to property consultant DTZ Debenham Tie Leung, 54 hotel projects, including redevelopments on former industrial sites, are planned or will be completed between now and 2007, providing a total of 27,830 rooms.
