The house and estate, of 130 acres (53 ha), are located directly to the south of Knole Park, near to the villages of Sevenoaks Weald and Underriver.

Originally built on the site of a Tudor farmstead in 1714, Riverhill House and estate were purchased in 1840 by John Rogers.

A keen botanist and a contemporary of Charles Darwin, Rogers purchased the property because of its sheltered location and lime-free soil.

The documentary featured the current owner and director of the house Jane Margaret Rogers and leading maze designer Adrian Fisher.

Riverhill Himalayan Gardens is a venue that offers its estate grounds as a setting for a variety of events, including weddings.
