Planning permission has been granted for the £28.5million project to transform an historic estate into a tourism hot spot, with 400 new homes and the creation of up to 525 jobs.
Councillors have given the go ahead for proposals for the Lambton Estate, near Bournmoor, which also feature office space and shops. The estate shot to fame in recent years when it was used to film period drama The Paradise.
But the plans must get final approval from Communities Secretary Greg Clark before work can begin.
The project would help fund the conservation of the park, with potential to turn the crumbling Lambton Castle into a wedding venue, boutique hotel or both, with between £26million and £28.5million needed to fund the work.
The idea of turning the private park into an attraction could bring in around 75,000 people a year, with spending by visitors expected to hit up to £750,000 a year and benefit to businesses in the area by up to £4million.
The papers for the scheme, which went before councillors this afternoon, also detail how two new roundabouts could be built off the A183 Chester Road to handle traffic.
