Thorpe Castle House

Thorpe Castle House is a manor house with probable medieval origins, believed to have been part of Thorpe Waterville Castle. The main structure dates to the mid-17th century, with subsequent restoration in the 19th and 20th centuries. It is built of squared coursed limestone with a Collyweston slate roof and has an irregular T-shape plan. The house is two storeys high with an attic.

The front elevation has four bays, with a later gabled cross wing projecting forward to the right of centre. A doorway to the right of the cross wing features a four-centred arch with moulded detail to the lintel, which is likely a reset feature. A 20th-century door now occupies this opening. The front features 19th-century two- and three-light stone mullion windows, positioned above the door and on the first floor and in the attic. A 20th-century two-light stone mullion window is situated to the ground floor left of the cross wing, with a single-light window above it. A 19th-century two-light stone mullion window with a transom is present on the first floor to the right. Return walls of the cross wing have single-light windows. The building has lateral stone stacks to the left and right. The gable parapets are ashlar, with the cross wing featuring a crow-stepped gable. The right side of the front elevation presents a two-window range of 20th-century stone mullion windows, with a gable to the left. A reset medieval lancet window is set in the first floor to the left of the gable.

The rear elevation has a projecting wing to the left, likely from the 19th century. A central gabled attic dormer, with a lateral stack attached to its right, is also present. A 20th-century stone mullioned bay window is located on the right. Ashlar gable parapets and stone stacks are positioned at the ridge and end.

The house may incorporate remains of Thorpe Waterville Castle, with Castle Barn, approximately 50 metres north-east of Thorpe Castle House, being the primary surviving structure. The house was likely converted into two farm cottages in the late 18th century. The interior is reported to have been remodelled in the 20th century, but has not been inspected.
