Description

Numbers 1 and 2, known as Percy Cottage, and Number 3, known as Forge Cottage, form a house terrace built as a single dwelling in the mid-17th century. The building was extended at the rear in the 18th century and was cased in red brick in the early 19th century. Around 1970, a one-window extension was added to the left side of Number 3. The structure features a timber frame with a plain tile roof, which has roughcast central ridge stacks and 18th-century stacks on the rear slope. It is two storeys high and has five 19th- to 20th-century glazing bar casements. In the center, there is a two-storey canted porch with a half-glazed door set in a segmental-headed frame. The interior of Number 2 includes a 17th-century bay on the right with a chamfer-stopped beam and a clasped purlin roof. There is also an inglenook in the half bay to the left, which has a wide roll-moulded bressumer. The rear of the building features three gable ends aligned in a row.
