In 1585, it was described as containing 10 messuages, a cottage, 10 gardens, 2 orchards, 100 acres of arable land, 20 acres of meadow, 50 of pasture 30 of wood and 40 rent.

In 1619, William Fanshawe purchased the house and 91 acres attached to it for £1150 from Edward Osborne. The house was owned by the Fanshawe family for over 300 years.
