The Nonsuch Mansion, an 18th century house, itself possibly built on the site of the Keeper's Lodge to Nonsuch Palace's Little Park, was rebuilt by architect Jeffry Wyatville in the picturesque gothic style in 1802-6. The present house has a castellated brick wall down one side and the gardens, which were partially laid out by Thomas Whately c.1830, feature a rose walk, sunken shrubbery, trees and flowers. The Friends of Nonsuch open the service wing of the Mansion in the afternoon of the 2nd and 4th Sundays of each month plus bank holidays from April to September.
