Calton Hall With Garden Walls, Gate Piers And Mounting Block

Calton Hall is a house with medieval origins, significantly altered in the 18th and 19th centuries. It is constructed of squared, roughly finished rubble stone with stone dressings, covered by a stone slate roof. The house is two storeys high, originally with three bays. The entrance, located in the right-hand side of the gable end, has a chamfered surround and a pointed arch, now containing a 20th-century door. To the left of the entrance is a two-light mullioned window on the upper floor, with a plain surround, and a similar window on the ground floor where the mullion has been removed; both now have 20th-century casements. The gable has coping and shaped kneelers. The front garden has a 20th-century window on the ground floor to the right, and a central entrance between two two-storey bay windows. Traces of earlier openings, now blocked, are visible between the bays. Stone ridge stacks are located at the gable ends and centre of the building.

At the rear, a first-floor 17th-century two-light chamfered mullioned window stands alongside a two-light window with a flat-faced transom and a ground-floor single-light window with a square surround. A two-storey extension to the right, under a catslide roof, contains a two-light window with a flat-faced mullion on the ground floor and a similar, shorter window above. A single-light stair window with square surrounds is also included, and the extension is heightened to span one-and-a-half storeys to the left.

Inside, both the ground floor and upper floor contain fireplaces with chamfered surrounds and four-centre arched lintels composed of two stone blocks. The former west gable end wall extended to the central ridge stack, which appears to contain traces of mullioned windows in the roof.

The garden wall to the east has an entrance flanked by ashlar gateposts, each with a moulded cornice and a ball finial. The base of the right-hand gatepost is cut to accommodate the first two steps of a four-step mounting block on the exterior wall face. The house was historically associated with John Lambert (1619-83), a Parliamentarian during the Civil War.
