Description

No. 20 is a small house built in the late 17th century and extended in the 18th century. It is constructed from coursed limestone rubble and features a gabled thatch roof. The house has end stacks made of 18th-century brick on the left and stone finished in brick on the right. The building has been extended from a one-unit to a two-unit plan and consists of one storey and an attic, with a two-window range. The exterior includes timber lintels over a 20th-century plank door and casements, as well as 20th-century dormer casements. The interior has not been inspected but is likely to be of interest.
