Lower Castleton Farmhouse and Garage

Lower Castleton Farmhouse and garage is a farmhouse and barn that has been converted into three houses. It dates from the mid-16th century, with additions from the 17th and 18th centuries, and alterations made in the 20th century. The building is constructed of painted rubble and has a slate roof.

The central block from the 16th century consists of two roof bays and features a lateral stack on the north side. To the east, there is a 17th-century extension with two roof bays and another lateral stack on the north side, followed by a single bay extension from the 18th century that has a gable-end stack. To the west of the 16th-century section is a three-bay barn from the 18th century, which is now a house over a garage. There is a 20th-century lean-to against the barn and part of the 16th-century section, along with two gabled extensions to the south of the 17th and 18th-century portions.

The building is two storeys high on the north side, featuring irregular fenestration. On the first floor, there are four 20th-century casements to the left, with the entrance to the house located to the right of the first window. There are also two windows (one of which is blocked) and one additional window, all of which are 20th-century casements. The ground floor entry to the 16th-century portion is on the right end, accessed through a 20th-century porch with a glazed door. To the left of this entrance, there are steps leading up to the former barn, which has weatherboarded framing. Opposite the entry to the 16th-century portion, there is a blocked doorway in the wall with a flattened two-centred head.

Inside, the 16th-century portion was originally one room and features moulded ceiling beams.
