The development will centre around the former Rannoch School
Plans have been submitted to create a £1.3bn luxury resort in Perthshire on the shores of Loch Rannoch.
An outline application to build a private members club consisting of a hotel and two golf courses was given to Perth and Kinross Council last week.
Developers Dall Estate and M James Developments said, if given the go ahead, hundreds of new jobs could be created at the site.
The application is expected to go before planners later this year.
The plans seek to redevelop the former Rannoch boarding school, closed in 2002, and create an exclusive resort featuring a health spa, a "body enhancement" clinic, some retail space and two 18-hole golf courses.
It would be situated on 430ha of the Dall Estate on the south shore of the eastern limits of Loch Rannoch.
A statement, attached to the planning application added: "The ambition of the redevelopment of the Dall Estate is to create a world-class private members resort in one of Scotland's most stunning settings.
"The aim of the proposal is to create a development of the highest quality and sustainability."
Mr James told the BBC website that the application was still at an early stage.
He added: "It is a very exciting development that could bring a new level of wealth to Scotland.
"We are very committed to it and have put in a lot of effort but I do not want to say too much until we have heard back from the council."
A spokeswoman for Perth and Kinross Council confirmed that the authority had received the application but said it would not comment on what is a "live application pending consideration".
