Caerhays Castle
Caerhays Castle is a country house on the south coast of Cornwall at St Michael Caerhays, between Truro and St Austell. It was designed as a mock-mediaeval castle in the early 19th century by John Nash, and later bought by the Williams family, who still own it. The gardens are open to the public each year in spring and early summer, and hold magnolia trees accredited with Plant Heritage as a National Plant Collection.

Scorrier House
Scorrier House was built by John Williams the Third in 1778 as the principle residence of the Williams family, who still live there. Enlargements were made in 1845 and 1908 following a fire that gutted parts of the house. The garden is also of note, much of it having been planted by William Lobb, a noted Victorian botanist and plant hunter. Today, Scorrier House can be hired for wedding receptions, private parties and corporate and outdoor events. The garden can be visited by appointment only.
