Description

Kempson House is a house dating from the late 17th century, with an early 20th-century extension of three bays to the east and later 20th-century extensions to the rear. The building is constructed of coursed rubble stone with a chamfered plinth, featuring 17th-century bays that have a slightly projecting ground floor or band course. It has an old tile roof with brick chimneys on the original gables and between the left bays. The extension includes a prominent external stone stack on the right gable, which has an irregularly chequered brick and stone top with three square brick shafts, the outer ones set diagonally.

The house is two storeys high with an attic and has seven irregular bays, with wider bays on the left and narrower ones on the right. It features leaded cross casements, which were renewed in the 20th century, with flush stone voussoir heads. There are three attic dormers with leaded casements, two-light in the centre bays and three-light on the right. The left bay has a 20th-century half-glazed door, while the third bay has a wide projection with a parapet made of red and vitreous brick, a modillion cornice, and a brick pediment above. This projection has similar cross casements, with the one on the right side being older, featuring a brick head and stone keyblock.

The front of the house has a segmental moulded brick arch over the upper window and a similar semi-circular arch over the 20th-century door below. The left gable of the main block has early 20th-century colourwashed render above the first floor, with the gable being half-timbered and overhanging. The rear extensions are built in a similar style, using stone with half-timbered gables. Inside, there is a notable 17th-century staircase in the projection, featuring turned balusters, a moulded handrail, closed string, and square newel posts with finely moulded and panelled finials. The interior also includes stop-chamfered spine beams, with one room showcasing a moulded wooden cornice. Additionally, there are two bolection-moulded marble fireplaces and a re-sited stone fireplace with a moulded cornice.
