Hackwood Park is a large 260-acre (110 ha) country estate that primarily consists of an 18th-century ornamental woodland and formal lawn garden in addition to a 51,681 sq ft (4,801.3 m2) mansion of symmetrical design.

[2] The bulk of the structure of the house currently standing was built from 1683 to 1687 for a son of the fifth Marquess, Charles Paulet, created Duke of Bolton.

[11] An extension to the orangery has added a 21st-century spa complex complete with pool, sauna, laconicum, and treatment room.

The interior contains panelling and a large fireplace of 17th-century style, with a carved ornamental festoon brought from Abbotstone House in Wiltshire.

[18] Grade II* listed buildings include an early 19th-century stable block and riding school,[19] and a menagerie pond pavilion, which dates from 1727 and was given as a gift by James Gibbs to the third Duke of Bolton.
