The manor of Southcote remained in the Blagrave family until the early 20th century, when it was owned by Henry Barry Blagrave. Henry died in 1927, though the manor house was demolished in 1921 after lying empty following the death of Wastel Brisco and his wife Sarah in 1891 and 1901 respectively. In 1920 the house had been purchased by a contractor with intentions to demolish the site, though the Society for the Protection of Ancient Buildings organised a committee to attempt to raise money to save the house. "The Sphere" reported that the bricks and oak panelling were in demand and were likely removed for re-use before the building's demolition.
