A large sale of the contents was held over a period of ten days in June 1922. The lavish interior fixtures and fittings, furniture and fine art collection were split up and sold to private collectors and museums around the world, mainly in the United States (see below). Adele did not, however, find a buyer for Cassiobury House; in July 1922 she died of a heart attack in her bath, and the house remained unoccupied for a further five years. Finally, in 1927 it was demolished and sold for its materials. Posters advertised "To lovers of the antique, architects, builders, etc., 300 tons of old oak: 100 very fine old oak beams and 10,000 Tudor period bricks". Much of the building material salvaged from the house, along with some interior fittings, were used to build a new house of the same name in Bedford, New York.
