The hall, the third building on the site, was completed in the mid 19th century for the family of a Welsh mining magnate.
[8] The 1870s hall is considered to be one example of the myriad of new types of buildings that were arising during the Victorian era to fulfil increasingly specialised functions.
Kinmel Hall was privately owned by members of the Hughes, Lewis and Fetherstonhaugh and Gill families until it was sold as a leasehold in 1929.
After the hall was sold, it became a boys school for a short while before it was converted in the 1930s to a 'rheuma spa', a health centre for the treatment of people with rheumatism.
The health spa was run by Florence Lindley, formerly headmistress of Lowther College, at the nearby Bodelwyddan Castle.
After businessman Eddie Vince restored the building, it was used as a Christian conference centre until the house was sold at auction in 2001 to a property company.
Despite selling the leasehold of Kinmel Hall in 1929, the freehold and the surrounding parkland remained in the possession of the Hughes, Lewis and Fetherstonhaugh family until 2001.
[8] In that year the freehold was sold, since then it passed to several owners before the property was to be put up for sale by auction on 12 October 2011 with a reserve price of £1.5 million which did not include the 5,000 acres (2,000 ha) of surrounding Kinmel Park.
[17][8] The company's declared intention was to develop the property into a hotel, but these plans never materialised and the hall was allowed to remain vacant.
[19][20] In early 2021 a campaign group published articles in the media with the aim of shaming its owners into either explaining their intentions, fully restoring it or selling it on.
[citation needed] In October 2021, the local council told the owners to stop renting out camping pods in the grounds of the historic property because they had not applied for planning permission and the location in the Grade 1 listed Venetian Gardens was not in keeping with its listed status.
