It is common today to see former Oast Houses, originally built to dry hops, converted into chic Kentish dwellings. The Waterlow family of Trosley Towers, near Wrotham, are credited with being amongst the first to see the capabilities of such redundant structures when, in 1903, they converted an oast house on their estate. Half a century later the building was renamed Tower Folly, and became home to experiments in sound.
