Stover House itself, then the home of the Templer family, had been constructed of Haytor granite in 1781. Granite's popularity as a building material was increasing and the reason for the quarry and tramway's creation was most likely a contract for George Templer to use the stone for London Bridge. Part of the British Museum, the old General Post Office in London and the Waltham Monument in Ludgate Circus were built of Haytor granite in the 19th century. The last use of Haytor quarried granite was the building of the Exeter War Memorial.
