Originating in part from around 1700, this elegant Grade II listed house at Roseworthy is thought to have been built for the wealthy Daniell family and is mainly of Georgian style with Victorian additions. The conservatory was designed by Silvanus Trevail, a leading Cornish architect, for John Rule Daniell.

For decades, the Daniell family were associated with the firm of Daniell and Thomas, solicitors, of Camborne. At the turn of the last century the house was let to tenants but was put up for sale in 1904. It passed to Mr R Arthur Thomas, Managing Director of Dolcoath Mine Ltd and later Chairman of the Cornish Chamber of Mines. It was he who made a milestone speech in 1943 in which he declared that “Instead of Cornish mining being dead, it is probably sleeping.” Unfortunately, the industry would vanish in years to come.
