Walls enclosing Kitchen Garden including Vine House and Pineapple House

The walls enclosing the Kitchen Garden, which include the Vine House and Pineapple House, form an irregular pentagon shape, with an east-west cross wall dividing the area into unequal sections. The outer walls are approximately 3.8 to 4 metres high. The southern wall is made of brick on the outside and stone on the inside, while the northern and western walls are stone on the outside and brick on the inside. The eastern wall is entirely brick, as is the cross wall, both featuring flat stone copings.

Near the eastern end of the southern wall, there is a stone doorway made of tooled stone, which is elliptical-arched and includes imposts, a keystone, and a pediment. An arched doorway is present in the western wall, and another near the eastern end of the northern wall. A gap in the eastern wall near the cross wall indicates the position of another doorway. In the southeast corner of the northern section of the garden, there is a hut, along with the remains of a similar hut in the southwest corner. The eastern wall has Garden Cottage built onto its outer northern end.

Built into the cross wall, with glass houses to the south and a heating plant to the north, are the Pineapple House and Vine House. The Vine House, located to the west, features a dwarf brick wall at the front, wooden framing, glazing bars, and sashes. The wall at the rear of the Pineapple House, located to the east, appears to have been raised. It has a dwarf brick wall with raking low walls on the sides, along with wooden framing and glazing bars from the 20th century. Inside, there are tiered brick beds with stone coping, and iron stanchions that support the rafters. On the northern side of the cross wall, there are attached buildings (some of which are lost) and pits associated with the heating plant, which retain important stove and pipe installations that provided heat to the glass houses, as well as evaporation trays.
