The malt house was an abandoned agricultural stone building. It was not listed but was probably built in the late eighteenth century. It is thought that the presence of a private dog-leg in the River Wey leading up to the building would indicate that barley was delivered by barge to the building for processing. The building was then used for storage of classic cars during World War II and then was largely unused. The conversion of this building saved a redundant building from neglect and secured its future survival and protection.
