Location and site

Idsworth Park is at the southern foot of the Chalk Downs of Chalton and Idsworth and is to the east of the settlement of Horndean.

Historic development

Idsworth Park was created in the mid-19th century by the Clarke-Jervoise family when the London-Portsmouth railway was built within yards of their original seat a mile or so east.
The house was designed by William Burn and completed by 1852. It was visible for miles around and was adjacent to the family’s favourite shooting ground, Wick Hanger. Its planting was planned and executed by Jervoise Clarke-Jervoise (1804-1889) and remains recognisable from his pencilled annotations. The house was approached by a carriage drive through parkland, past the home farm, to a west entrance flanked by plantations and walks. East of the house a parterre and terrace led to lawn and low planting, with a NE vista up to Folly Wood and a SE vista down to Northwood Farm. North of the house were an orchard, walled garden, bothy and icehouse, with woodland walks through surprisingly steep terrain. The orchard excepted, these features survive, maintained by a committed Residents Association. An undated sunken garden has been emptied of debris and replanted.
After 1892 the Clarke-Jervoise family were not always able to live at Idsworth, but in 1912, under the 6th baronet, H S Goodhart-Rendel added a music room to the south-east corner to overlook Burn’s vistas. In 1920, under the 7th Baronet, Idsworth had glasshouses of orchids, peaches and nectarines. Under Major Arthur Francis Clarke-Jervoise, who lived at Idsworth from 1948 until his death in 1974, the grounds provided grapes for the table at Christmas and a daily carnation for his buttonhole.
