Tree House, also known as The Tree, is a medieval timber-framed house on the High Street in Crawley, a town and borough in West Sussex, England. It is the original manor house of Crawley, and was built in the early 15th century and rebuilt in the mid-16th century. It now has a modern exterior, but the old structure is still in place inside. Situated in a prominent position facing both the High Street and The Boulevard, two of Crawley town centre's main roads, its name commemorates an ancient elm tree which stood outside for hundreds of years and was one of Crawley's landmarks.
