A FASCINATING
STORY

Combining contemporary design with traditional architecture, this Grade I listed building sets new standards through superior craftsmanship and attention to detail designed into its restoration and refurbishment. Built in 1775, the interiors are some of the most splendid and best preserved of the architect Robert Adam and, as a result, are of national importance.
