Sandhill Park is a grand Grade II* Listed Mansion House, located on the edge of the Quantock Hills in Somerset, an Area of Outstanding Natural Beauty. Alongside the main house there are beautiful, historic barns, stables and wall gardens.

Sandhill park was built around 1720 by John II Periam, and originally called “Hill House” and kept as a private residence until 1913. During World War I the house was used as a prisoner of war camp for German and Austrian Officers, before being converted into a home for children with disabilities in 1919. In 1940 it was requisitioned by the military becoming the 41st General Military hospital and was then leased to America as a neurological hospital in 1941. The hospital remained in military use until 1945. In 1948 it was reopened as a psychiatric hospital under the national health service.

The hospital was sold in 1991 and housing built on part of the area. On 22nd November 2011, the house was badly burnt by a fire, which was caused by arson. This along with the water damage resulted in extensive damage to the east wing, roof and top floor of the building.


We are currently undergoing a programme of emergency works to stabilise the Mansion House and prevent any further damage from the elements. Following this important work the plan is to convert the Mansion House into a multiple unique apartments, with the benefit of a beautiful location and individual outdoor space with each home.
