Marble Hill House is set in 66 acres of outstanding riverside parkland
The grounds slope gently down towards the Thames and were laid out in the early C18th with advice from Alexander Pope and Charles Bridgeman with short parallel rows of chestnuts to the left and aright of the house facing the Thames, with slightly terraced lawns between them. Today there are small areas of woodland to east and west of the house, with broad lawns to north and south flanked by trees along the approach drives to the north and to left and right of the lawn overlooking the Thames. There are spacious lawns to east and west with a noted black walnut of the mid-C18th in an enclosure 200m to south-east.
