Description

Ashwell's Barn is a 17th to 18th century timber-framed and weatherboarded barn consisting of three bays. It features a brick plinth and old tile roofs. The barn has been converted into a house, which includes plain side-hung casements. On the south side, there is an aisle and a central door, along with two swept dormers. The farm buildings to the south have also been converted. Additionally, there is a lean-to on the north side and queen strut roof trusses inside.
