Great House

Great House is an early 18th-century Georgian building with a double-pile plan that has undergone some later alterations. It is a two-storey structure with a basement and attic, featuring a five-by-two window pebbledash front and a plinth. The building has steep slate roofs, a moulded eaves cornice, and brick chimney stacks, with the original stack located on the left and featuring recessed panelling. A central pediment is adorned with a pointed three-light attic window, while below are twelve-pane early 19th-century sash windows.

The entrance boasts an exceptional central late Baroque doorcase, complete with a broad bracket cornice, a foliage entablature, and Corinthian reeded pilasters, leading to a later four-panel door and fanlight. The right end of the building is plain pebbledash with two-light windows. The ground falls away, raising the rear of the house on a terrace above the garden, which is supported by a rubble revetment wall. The rear features irregularly spaced windows of various types with voussoir lintels. To the west, there is a two-storey structure with a pitched roof that retains a chimney stack; this area was formerly the servants' hall but is now in poor condition.

The building previously housed a museum that included the Benjamin West painting now located in the Church. At the time of inspection in January 1986, it was undergoing restoration.

Inside, the layout follows a central stair-passage type, retaining an entrance hall with panelled doors leading to front panelled rooms. To the right, the cornice advances over panel borders and cockle shell niches. A semicircular arch leads to a fine early 18th-century dog-leg staircase, featuring fluted banisters, a moulded handrail, and foliage ornamentation on the tread ends. The first-floor landing has twin semicircular arches that divide the front and rear sections of the house, complete with keystones and panelled soffits. The interior also boasts deep wall panelling, cornices, panelled shutters, and doors. The original seven-bay roof is retained with pegged timbers, although some alterations for later accommodation have been made.
