Description
Mercia Farmhouse is a 17th-century house constructed from coursed rubble stone with timber lintels above the openings. It features an old tile roof and flanking chimneys, with the right chimney having two square brick shafts set diagonally on a stone base. The building has two storeys and an attic, with three irregular bays. The right-hand bays contain irregular three-light casements, with the upper right window featuring leaded outer panes. The left-hand bay has a paired barred casement on the first floor and a half-glazed door situated in a timber porch that has a lean-to slate roof. There are also two small gabled dormers with paired casements. To the left, there is a 20th-century single-storey extension with a flat roof.
