The present regency style house, known as The Mansion House (and originally named Prospect House), was built by John Liebenrood in the late 18th century. John Engelberts Liebenrood (1754-1821) was born in Germany in 1754. His birth name was John Engelberts Ziegenbein and he immigrated to England and obtained naturalisation in 1781. He lived with his great uncle John George Liebenrood, a very wealthy merchant in Purley. When his uncle died in 1795 he inherited his fortune and in accordance with the will changed his name to Liebenrood. In the following year he married Lucy Hancock whose brother was Rear Admiral John Hancock.
