Dundonald Links, scene of Rafa Cabrera Bello's brilliant Scottish Open triumph in 2017, was sold by Loch Lomond Golf Club for £4.5million.
Darwin Leisure has plans to completely transform the clubhouse at Dundonald, creating a high quality facility with new practice, leisure and dining options.
The Ayrshire course will join Darwin Escapes' portfolio of courses, which includes The Springs in Oxfordshire and the KP Club in Yorkshire.
Chief executive of Darwin Alternatives, Anthony Esse, is aware of the history and stature of the club, and is excited about the opportunity to improve Dundonald for all.
"Dundonald Links is world-renowned for good reason," said Esse.
"We are absolutely delighted to announce the addition of Dundonald Links to the Darwin Escapes portfolio of golf courses.
"It is simply a stunning place to play golf, and we plan to make a significant investment to ensure that the clubhouse facilities are worthy of this wonderful course.
"I can't wait to work with the highly-skilled team at Dundonald Links and implement the changes needed in order to achieve this."
Although it only opened in 2003, Dundonald Links is now regarded as being one of the 100 best courses in the world.
