Ilkley's first hydropathic establishment was built at Ben Rhydding in 1843–4 in a Scottish baronial style to exploit the supposed health-giving properties of the town's waters.
Well-off people with rheumatic and arthritic aches and pains paid to be immersed in hot and cold baths in an alternative medicine known as hydrotherapy, resulting in the construction of hydros in the mid-century and "spa-tourism".

A group of Bradford businessmen, led by Benjamin Briggs Popplewell, formed the Wells House Hydropathic Company and acquired land, and in February 1854, commissioned the Hull-born and Leeds-based Cuthbert Brodrick to design their building.
He was occupied with the construction of Leeds Town Hall but took on the Ilkley commission concurrently.
It came at a cost of more than £30,000 (equivalent to £2,824,000 in 2019) and was completed by 1856, opening on 28 May. Because of its isolated, moorside location, Wells House is the only building by Brodrick known to have been surrounded by a designed landscape, the work of Joshua Major (1787–1856), a Yorkshire landscape gardener.

The most famous visitor to the Wells House Hydro was the naturalist Charles Darwin, who stayed with his family in October 1859.
He undertook the "water cure" as well as walks on the Moor.
Due to the unusually early winter, his daughter Henrietta described their stay as "a time of frozen misery".
The family left Ilkley on 24 November, the day of publication of his work On the Origin of Species.
Darwin finally left for London on 7 December, a stay of almost nine weeks.

By the 1880s, hydrotherapy began to decline as the benefits of the treatment were discredited.
The building subsequently found a new use as a hotel for the next seventy years; this featured a Winter Gardens with sprung dance-floor, raised bandstand, and a 3-span roof supported by decorative arched cast-iron trusses built on top of the terrace.
The impact of two world wars saw the hotel's closure.

The local authority took over the building and opened the Ilkley College of Housecraft in 1952, with parts of the grounds being developed to provide additional accommodation for the college over following years.
Known as the "pud school", the institution became Ilkley College of Education and then merged with Bradford College to form Bradford and Ilkley College.
The site (including ancillary buildings) which contained around 100 staff and 400 students, was considered too expensive to run and it was closed and sold in 1999.
Later building additions were removed and the building and the surrounding site were scheduled for residential development.

Wells House is recorded in the National Heritage List for England as a Grade II listed building, having been designated on 20 May 1976.
Grade II is the lowest of the three grades of listing, and is applied to "buildings that are nationally important and of special interest".
It also sits within the Ilkley Conservation Area.

The building was refurbished and converted into apartments between 2001–03 by the developer Magellan Residential, retaining some gardens to the north and west while residential properties occupy the rest of its grounds.
The £7.5 million refurbishment, which centered the flats around a new glazed atrium in place of the courtyard, won Bradford District Design Award 2004 for Best Residential Conversion, RICS Pro-Yorkshire for Best Residential Scheme 2003 and the Ilkley Civic Society Award for Conservation 2003.
