Originally known as Silksworth House, the house was constructed in the latter 18th century by William Johnson. On his death in 1792, the property passed to his friend, Hendry Hopper, a Durham lawyer. He in turn passed the house to his nephew, Thomas Hopper, who in turn passed the property to his daughter Priscilla along with a considerable portfolio.

In 1831, she had married William Beckwith, a Major of the 14th Kings Dragoons. Following the his role in suppressing the reform riots of Bristol that same year, where up to 250 people were killed or seriously injured, Beckwith was retired on half pay with the rank of lieutenant-colonel. With time and his wife's estate on his hands, Beckwith made extensive renovations to Silksworth House, adding the grand forebuilding and extensive landscaping of the grounds. In particular, the lake to the west and the walled garden were added under Beckwith's rebuilding, and the couple acquired a number of French works of art to decorate the property. On Beckwith's death in 1871, the house was inherited by a nephew whose family resided there until 1890. The estate was leased from this period and tenanted by the potter Christopher Maling until 1902.

Charles Doxford acquired a 99 year lease on the house in 1902 and began extensive landscaping and redevelopment of his own. Many of these schemes did not outlive him and the house passed to his children in 1939 when he died. His daughter Aline Doxford was the house's primary resident but only occupied a small portion of the property until her death in 1968. She bequeathed Silksworth House to Sunderland Corporation and they renamed the property to Doxford House in honour of the shipbuilding firm and its contribution to the city. The gardens were redeveloped into the municipal Doxford Park and the main house and its immediate grounds became a halls of residence for Sunderland Polytechnic. In 2001, the University passed the house and gardens to the Lazarus Centre, a rehabilitation charity, but they could not maintain the property and the building has been empty since 2006.
