WHARF Properties is taking no chances with its spectacular new Times Square development at Causeway Bay. Not content with a series of artists' impressions of the complex, one entire floor of the parent company's head office in Central has been turned into a life-size show suite to illustrate exactly what level of finish - internal and external - can be expected on the completed project. The show suite was built on the 12th floor of World International House for $8.5 million, and incorporates granite, marble, chrome, tile, leather, glass, carpeting and lighting features identical to those being fitted in the development. Times Square will comprise a 16-storey retail podium together with more than a million square feet of Grade A office space in twin towers of 39 and 46 storeys. There will also be six underground floors, with loading and unloading areas, parking for 700 cars and direct access to the Causeway Bay MTR station. Ms Doreen Lee, director for leasing agents for the development, Harriman Leasing, said: ''We wanted potential clients to be able to see and feel the true quality of the development for themselves. ''In terms of the scale, the materials used, and the attention to detail, this show suite is an exact replica. It is literally a case of what you see is what you get,'' she added. Times Square will showcase the first spiral escalators in Hongkong, with two pairs linking the three floors already taken by Lane Crawford in the retail complex. The half-size escalator models are among the highlights of the exhibition. But the genuine articles - at $8 million a set - are certain to be an attraction in their own right. Only eight sets of this type of escalator exist in the world. Each set has been custom-made in Japan to individual specifications by Mitsubishi. There are two computer-controlled show suite tours, one each for the retail and office complexes. Lasting about 30 minutes, they progress through a series of rooms illustrating different aspects of the development. Both begin in the ''piazza'', a miniature version of the 33,000 square foot real thing, with its patterned granite paving, a water fountain and, naturally, a clock tower. From there, visitors are ushered into a small cinema for a short video which offers an idealised image of the perfect business and office environment, and then lays claim that Times Square fulfills that image. From there, the tours diverge, but remain equally impressive. Through doors that swish open Star Trek-style, a series of cut-away scale models are revealed. To the accompaniment of an authoritative commentary, synchronised lighting illuminates the entry and exit points for people and vehicles, and stresses the benefits of the location for the convenience of public transport. Then potential office space buyers are confronted with an astonishing lobby. Fully lined in marble, the model lobby comes with lift doors that open as normal, but lead into a range of different exhibition spaces. Step into one, and you're in a model of the office lavatories. Take the next, and you are in a large, airy office. The dimensions are exactly those in the real development, as is the carpeting, lighting, and air-conditioning. Here, the more technical aspects of the new building are highlighted in a series of automatic demonstrations. A key selling point for Times Square is the ''intelligent building'' concept. What this means is that sophisticated computerised control systems regulate all the vital functions of the office space. The Building Automation System (BAS) monitors and controls the lighting of public areas, air-conditioning and night-time access to office floors, via a security key-card system. For the business user, there is a state-of-the-art fibre optics communications system. The retail side of the show focuses more on the expected 12,000 office workers ''above the shop'' and the potential of the 150,000 people who pass through Causeway Bay MTR daily. The retail space is in four major sub-sections: market and cinema, Lane Crawford Place, Kiddies World, and the Food Forum, all centred around the six-storey atrium.
