Artist's impression of how the completed SnOasis complex may look
The SnOasis winter sports centre near Ipswich will open by the end of 2014, according to the developers.
Godfrey Spanner, managing director of Onslow Suffolk, says construction of the sports complex is due to begin in September 2011.
"On Christmas Eve we managed to get the legal agreements signed by all parties," said Mr Spanner.
"We're ready to apply for the newt licence to allow us to get on with the ecology during January."
Onslow Suffolk wants to create a £350m complex with an indoor ski slope, ice rink, hotels as well as shops and apartments on the former quarry.
"We acquired the site in 2001 and applied for planning permission in 2004," said Mr Spanner.
"We received consent in 2005, but with conditions that we couldn't meet.
"We've been trying to get through those conditions ever since and in November we finally got the green light."
Developers are confident SnOasis will open in 2014
Mr Spanner says builders are moving on site in February and March, with the plan to build 400 homes in the next five years.
Despite several set backs, Mr Spanner says he is "absolutely, totally confident" that the public will be on the SnOasis snow and ice by 2014.
"We're scheduled for the second quarter of 2014 but at this minute I'm working with the team to see if we couldn't get the snow dome itself operating before that time," he said.
"One of the planning conditions is that we must start the snow dome first, so if we're going to do that we ought to open it up to our athletes and to the public before [the rest of the development is opened].
"It just means that people can't stay on the site, which is our overall intention."
