The house is associated with gardens that were designed by James Mellor, junior, and are known as Mellor's Gardens. They have a religious theme based on John Bunyan's The Pilgrim's Progress. A pathway takes the visitor through and past features included in the book, ending in a two-storey building on a ridge representing the Celestial City on Mount Zion. The gardens are designated at Grade II in the Register of Historic Parks and Gardens. The gardens contain the following structures that are designated as Grade II listed buildings. Mellor's private chapel dates from 1844, and attached to the chapel is a barn dating from the 17th century. To the north of the chapel is a sundial dating from about 1850. Also in the garden are three pedestal tombs of members of the Mellor family and James Walker.
