Waterside Barn is one of the four unique homes which make up Bradbourne Mill. The four properties together were historically known as Bradbourne Mill Farm and is thought to be the oldest surviving water mill in Derbyshire.
An Okeover Charter confirms the site dates back to circa 1180 and the land owner at this time was Sir Geoffrey de Cauceis - the great grandson to Henry de Ferrers.
Later, Sir Robert de Bradbourne rented the mill in 1247 to three canons of Dunstable Priory who built a Manor House and Grange buildings in Bradbourne near to All Saints Church. The canons would mill their grain into flour and employed many farm hands and tradesmen from the locality to help them.
