The Sandhoe estate was owned by the Errington family of nearby Beaufront, but when Henry Errington died childless in 1819, it passed to his great-grandnephew Rowland Stanley of Puddington Hall, Cheshire, son of Sir Thomas Stanley Bt (see Errington baronets). Stanley changed his name to Errington. He was High Sheriff of Northumberland in 1855 and became the 11th Errington Baronet in 1863.
In 1850 he commissioned architect John Dobson to rebuild the old house. The south and east fronts are four-bayed with two storeys and alternately gabled attics. The northwest service wing incorporates some of the fabric of the original house.
