A new 18 hole golf course has been given permission to open at Leisure Lakes in Mere Brow.
It is the latest in a series of plans to redevelop the recreational site, which will also see 50 chalets built in woodland, and a new central amenity building.
The complex already has a nine hole golf course and 18 bay driving range, which currently operates as Southport Golf Academy.
But bosses say the additional 18-hole course is necessary to stop young talent leaving the area.
Leisure Lakes owner Philip Whitter said: “The academy is superb, the best in the area, and we get 350-400 new golfers coming through it every year.
“The nine-hole course is fantastic to practice on, but when you get better, it’s too easy.
“We lose a tremendous amount of players to other courses, so we’re very pleased that this will allow us to attract more people into Leisure Lakes, boosting the local economy.
“With the woodland chalets and the new central building, it’s a very positive time for Leisure Lakes, and with the investment, we’re hoping to attract more people in.”
Work on the new golf course is expected to start early next year, on agricultural land adjacent to Southport New Road.
It will involve the formation of water features, buggy tracks, two storm shelters and landscape planting.
Planning agent Andrew Watts assured West Lancashire Council that “elements can be completed in a manner that preserves the openness of the Green Belt.”
Work will also be done improving ditches to create habitats for water voles which are known to live in the area.
Tarleton councillor John Mee said he welcomed the investment. He said: “It’s been a very popular spot for a number of years, and a new golf course will be a big draw for a lot of people. Investment in the local area is welcome.”
