In the 1700s and early 1800s Gate Farm and Arms Farm were two small unnamed farms, but were farmed together from about 1830.
According to the Victoria County History, Arms Farm farmhouse 'was possibly built in the later 18th century. It has a two-storeyed main north—south range with a symmetrical west entrance front. A narrow single-storeyed service wing along the east side was heightened to match the main range.'
The farm was possibly named after the Inn on the opposite side of the High Street, which was called the Tylney Arms Inn before becoming The Welllesley Arms in the early 1800s.
