Clevedon Hall, a 150-year old mansion in North Somerset, is set to re-open as an events venue next week following a £3m refurbishment.
The historic building, previously called Frankfurt Hall, was built for sugar refining magnate Conrad Finzel using designs by Bristol architect firm Foster and Wood.
Current owners Peter and Sally McCarthy bought the hall in 1991from St Brandon's girl school for use as their corporate headquarters before making it available for private hire from 2010.
The property's re-launch as an events venue 27 November follows an extensive three-year revamp.
Maintenance on the upper two floors, the creation of 25 bedrooms and suites, and the restoration of many original features is currently underway ahead of future plans to turn the venue into a hotel.
John McCarthy, general manager of Clevedon Hall, said: "We have restored as much of Clevedon Hall's history as possible and have worked closely with English Heritage and the local conservation officer to ensure the designs are just right.
"We told our teams that we wanted the bedrooms and suites to feel like a home away from home, with a traditional finish, whereby the bedrooms and suites all embody the same English country house theme throughout.
"The house has kept its historic character, however we have just added in a contemporary twist, which runs throughout the whole property."
