DETAILED plans have been submitted to transform Bretton Hall into a luxury hotel and build a business park in the estate grounds, creating up to 400 new jobs.

Developer Rushbond PLC has applied to convert the grade II listed building into a 120 bedroom hotel, in the 500-acre grounds of Yorkshire Sculpture Park, West Bretton.

Outline planning permission for the idea was given in 2009 but more detailed plans have now been submitted to Wakefield Council, and Barnsley Council is being consulted on the proposals.

The project would involve a total refurbishment of the existing grade-II listed Georgian mansion, and a new bedroom wing would be built. There will also be restaurants, bar, spa, conference and wedding facilities.

The first phase will create a 77 rooms, with 120 expected in due course, and it is thought the hotel will have either 4 or 5 stars, depending on the facilities developed.

As well as redeveloping the hall into a hotel, the proposals also include a 100,000 sq ft business park with refurbished pavilion-style office accommodation.

Rushbond believes the business park has the potential to generate up to 400 new jobs.

Jonathan Maud, managing director of Rushbond Plc, said the submission of plans 'marked a milestone'.

"The submission of the planning application is an important milestone in our shared vision to sympathetically transform Bretton Hall into a truly stunning hotel and business park opportunity, that will attract new businesses to the region and create long term sustainable employment."

Bretton Hall is owned by Wakefield Council, which acquired the campus from the University of Leeds in 2006 to ensure any development had 'synergy' with the adjoining sculpture park.

If the planning application is successful, it is anticipated work will begin in February next year.

The initial phase of construction will be for the hotel development and the first phase of the business park is expected to be available for occupation at the end 2014.
