THE multi-screen cinema, bowling alley, restaurants and car park being built at Broad Street, Halifax, should be open for business by March 2012.
Not far behind will be the 100-bed Premier Travel Inn, a new health centre, offices and space for two large shops.
Barry Gregory, chairman of the development company the Gregory Group, said the 50 million scheme was one of the biggest his firm had been involved with and he was delighted work was now well under way.
"This will bring enormous benefits to Halifax and the surrounding area and we are pleased to announce that more than 70 per cent of the available space has been pre-let," he said.
Yesterday, the Courier reported how the banking giant Santander has agreed to underwrite the development to the tune of 35 million, creating 220 jobs in the longer term and giving an 8 million boost to the local economy.
Another 3 million has been pumped in by the regional developnent agency, Yorkshire Forward.
The key to the success of the Broad Street Plaza will be the Vue multi-screen cinema, which has been a part of the project for the past six years.
Area manager Janice Craig said the town had been without a cinema for too long and the aim was to provide the best possible facilities with nine screens and provision for 3D viewing.
Kevin Murray, Whitbread's acquisition manager, said the new hotel would satisfy a growing demand for overnight accommodation and a first-class Table Table restaurant would be an additional attraction.
The search is still on for a bingo operator but confirmed retailers include Wetherspoons and Frankie and Benny's restaurant chain.
A bowling alley operated by Tenpin will be set up on the ground floor of the complex.
The second phase of the development includes 42,000 sq ft of office space which Calderdale Council had shown an interest in at one stage but the council's office strategy is still under review.
Director of service development for the Calderdale and Huddersfield NHS Trust, Lesley Hill, said the new health centre would replace the nearby Laura Mitchell Clinic.
"This is an old building that is not fit for purpose and we want to create new state-of-the-art, modern environment which is far better suited for 21st century healthcare.
"Services there will include sexual health, children and adult therapy and our child and adolescent mental health services," she said.
The council's economy and environment spokesman Barry Collins (Lab, Mixenden and Illingworth) said: "The whole project will have a big impact on the town centre.
"It is important for the future of our community and we are hoping to minimise any inconvenience."
Work on site began more than a month ago and the main steelwork for the buildings is expected to be erected in November.
