Description

Mongewell Farmhouse is a farmhouse that likely dates from the early 18th century, with extensions and alterations made in the 19th and 20th centuries. The building has a brick base and is constructed of flint with brick bands and dressings, topped with a plain tile roof and featuring brick end stacks. It is two storeys high with an attic and has a three-window range. The central entrance consists of a six-panelled door, and all openings have two-light casements. There is a gabled dormer located at the centre of the roof. The interior has not been inspected. To the right of the main structure is a single storey and attic wing.
