One of two linked terraced Garden Buildings on N.Side of Park at Castle Hall

There are two surviving buildings, in sequence, first a large vaulted sub-structure to a terrace overlooking the fish-pond, and then a much longer roofless stone building of considerable architectural elaboration and some scale. The vaulted part has a plain rubble 3-arch front with rough voussoirs and an interior (formerly plastered) of three and a half bays by two bays depth, groin vaulted with plain square piers and blank arches on rear wall. Inner W door has eroded stucco doorcase. Pond in front has small dock for skiffs.

The building to the west, called the pinery without clear evidence, is heavily overgrown, of 3 plus 6 bays, roofless but formerly with monopitch N facing roof back to rear retaining wall. Rubble stone, classical detail with remnant of cornice stepped up at east 3-bay section, upper level small lunettes and main front divided by raking buttresses between round arched recessed panels with big cambered headed windows. Rough stone voussoirs. Arched W end wall doorway. Interior has sunk water-tank in floor with runnels and a possible boiler chamber.
