A new leisure club, spa, ballroom and bedrooms are set to be built at The Belfry Hotel & Resort near Birmingham.
The renowned golf resort, which has previously held The Ryder Cup four times, secured planning permission for a major revamp in summer 2017 but has since gone back to the drawing to revise its proposals to focus more on the golf side of operations there.
The Bel Air nightclub is still in operation at The Belfry but BirminghamLive understands it would be closed and demolished as part of the project.
It is estimated that the resort's 650-strong payroll could be boosted by another 150 jobs as a result of the redevelopment if the scheme wins the backing of North Warwickshire planning chiefs.
The hotel currently has 320 bedrooms but the project would see an additional 144 rooms constructed in a new building overlooking the world-famous Brabazon golf course and a linked 600-seat ballroom and banqueting facility.
A leisure club, next to the 18th hole of its PGA National Course, is also in the plans and will feature a family-orientated leisure pool, gym, fitness studios, café and changing facilities.
The relocation of the existing leisure facilities will also allow space within the resort's buildings for a spa.
Several elements of the consented 2017 scheme have been either amended or scrapped altogether, including plans for a new water park.
Planning and development consultancy Lichfields is leading the project on behalf of The Belfry.
Planning director Ian Kettlewell said: "The Belfry wants to build upon the resort's golfing tradition and success so that it continues to operate as a world-class golf and leisure destination into the future.
"The new guest rooms will face onto the tenth hole of the world-famous Brabazon course and feature private balconies giving open views across the golf course and resort.
"The ballroom will be connected to the new guest rooms by a two-storey arrival space and will also face onto The Brabazon."
Lichfields said around 160 construction jobs would be supported during the redevelopment, the extra facilities would boost the local economy by around £8 million a year and a further 125 events could be hosted annually.
A planning application is due to be submitted to North Warwickshire Borough Council in the summer and construction could start in early 2020.
A public consultation event takes place on Wednesday May 15 at Middleton Recreation Rooms, in Church Lane, Middleton, from 4pm to 7pm.
