Description

Hermongers Farmhouse is an L-shaped timber-framed building that dates from the 17th century or earlier. The ground floor has been rebuilt in red brick, while the upper part is tile-hung and shows traces of a bressumer beam. The roof features Horsham slabs on one side and tiles on the other. The windows are casement style. The north wing is likely a later addition from the 17th century, constructed of red brick with grey headers. A massive chimney breast is located at the back of the building.
