The long-awaited Bluestone project will be launched with a splash in spring as construction work begins on the first phase - Waterworld.

The £62 million Bluestone development, which has been over seven years in the planning, can now forge ahead after its main opponents called it a day.

Work has been held up for the last two years after the Council for National Parks launched a legal battle against the project.

But following a Court of Appeal ruling, the organisation confirmed it would be taking no further action.

Bluestone is the brainchild of William McNamara. He said: "We have lots of paperwork and legal issues to sort out, but the Court of Appeal decision was the watershed which allows everything to move forward."

Plans for Waterworld will be finalised in the new year, but it will be spring before construction can begin on the site near Canaston Bridge.

Waterworld will be opened to the public - locals and visitors - between Easter and summer 2007, and it will boast the biggest Boogie Wave in the UK. The one-metre high wave will allow indoor surfing - a boon for beginners or all-year-round surfing enthusiasts. There will also be a rapid river, two flume rides, a children's interactive water play area, a lazy river, hot tub and lounging area.

"The idea is to create a sub tropical environment with a consistent 80 degree centigrade environment," said Mr McNamara.

It will take another six months - almost to the end of 2007 - before the Celtic holiday village, with its 30 cottages, 30 studio apartments, catering, retail and sport facilities, is completed. By then 240 of the 335 timber holiday lodges should be ready.

Said Mr McNamara: "The remaining lodges and the Snow Dome should be ready by 2008."
