The icehouse lies to the north of the North Tower. It is almost certainly contemporary with the tower's brick lined cellar. Externally it comprises a rectangular earth mound orientated east to west and measuring 5m x 12m. It abuts the north wall of the tower. The structure is entered via a stone-lined L-shaped passageway. At the end of the passageway there are fittings for two sets of rectangular doors. This second doorway leads into a brick-lined chamber below ground level. The double doors would have kept the room as cold as possible. Access into the chamber is via a set of steep wooden stairs. The brick-lined barrel vaulted chamber is 3-4m deep with a small square delivery hatch in the east wall. Below the hatch is a ramp made from two angled timbers which have been recently used to drop masonry blocks into the interior. The timbers are not original.

Remains of an ornamental octagonal pool, largely intact but in poor condition and in danger of deterioration. With central stone base, probably a fountain.

Remains of grassed terraces built into sloping ground north of the terrace wall. The embankments are now covered by self-seeded Sycamores. This area was the site of a conservatory, described in Gardeners Magazine in 1834. Now piles of bricks and stone remain. A stone boundary wall and railings survive, along with iron tree guards, stretches of stone kerb and drainage. There is a fine 19th century cedar tree to the east of the towered gateway. Plinth of an urn or statue. The fragments of garden ornaments are in danger of deteriorating quickly. Views through the area are obscured by the Sycamore.

The formal terrace is defined to the south and west by a battered sandstone wall, parallel with the former south face of the Nash House (HER 8183), that ranges in height from 0.5m to 3m. Some remnants of ornamental planting survive, including yew and rhododendron. The stone base of a garden ornament is hidden in the undergrowth to the east. Two large trees, a Wellingtonia and a Giant Redwood, survive along the edge of the terrace walls. A group of mature Yew trees occupy the south-west corner of the terrace around an artificial mound. The masonry and copings of the terrace wall are mostly intact although only remnants of the railings remain. The once open character of the grassed terrace and its relationship with the Nash House has virtually been lost. Views from the terrace over fields to the south are still uninterrupted, but the terrace itself is very overgrown and its shape difficult to discern beneath the weeds and shrubs. Possibly built over an earlier terrace.
