Strawberry Hill House
Strawberry Hill is a castle-like country house built by the writer and politician Horace Walpole, 4th Earl of Orford, between 1749 and 1776 on the River Thames near Twickenham, London.
Client Profile
In 1923 Strawberry Hill House came into the possession of St. Mary’s University College in Twickenham. Its use as a training centre for teachers led to disrepair.
In 2004, Strawberry Hill was included on the World Monuments Fund’s biennial list, which lists particularly important but endangered historic monuments. In 2007, the building was leased on a long-term basis to the Strawberry Hill Trust, which completed an extensive renovation work during which all damage was repaired and later installations removed.
Generous support was provided from the Heritage Lottery Fund, The World Monuments Fund, English Heritage, the local community and a number of Trusts and Foundations, £10 million was raised and the restoration of Strawberry Hill House & Garden was accomplished. It was opened to the public in October 2010 and in 2011 won the Georgian Group Award for the best restoration of an 18th century Country House and the Europa Nostra Award in 2013.
