The house is dated to the late 18th-century but was extended in the mid 19th-century for the Gully-Bennett family. It is a two-storey house, made of gritstone and granite flush quoins, with a dalabole slate roof and twelve paned windows with Georgian glazed panels, five of them at the front.[4] The central entrance hall on the north-east front leads to a large oak staircase and the library (refurbished in late 19th -early 20th century) and main drawing room are located on the south-east side. The drawing room has a central floral rose and a Carrara marble chimneypiece. It was recently restored by Robert Rowett Architectural Services.[5]
