Description
The Old Manor House is a 15th-century timber-framed house with plaster infilling. The first floor is partly close-studded, while the ground floor was rebuilt using sandstone. It has a roof of Horsham slabs. Casement windows are present. The south front has three windows, with evidence of two blocked original windows containing wooden mullions. The east front features a recessed centre with curved braces supporting the eaves, and some timbers have been renewed. Four windows are visible on this front. Later additions were made to the west and north of the original structure.
