Walled Garden With Glasshouses And Sunken Garden, Marchmont House

The Walled Garden with Glasshouses and Sunken Garden at Marchmont House likely dates from the early 19th century, with some later alterations. It features a rectangular-plan walled garden, approximately 8,400 square meters, with greenhouses and potting sheds located to the northeast. To the west, there is an irregular-plan outer walled garden, about 700 square meters in size. The tall, coped walls have red brick inner linings on the northwest and northeast sides, while the southwest elevations consist of harl-pointed rubble walls. The southeast wall is partially missing. The garden includes cream sandstone ashlar door surrounds, boarded timber doors, a carved coat-of-arms above the northwest door, and an inscribed sandstone plaque above the northeast door. Little of the original layout remains.

The greenhouses are a symmetrical range of five bays from the late 19th century, attached to the inner elevation of the northeast wall, with gabled projections facing southwest. Inside, there are original work benches, decorative floor grills, plain iron brackets, and levers for opening the ridge vents.

The potting shed to the northwest is a single-storey, mono-pitched structure made of squared and snecked tooled sandstone rubble with tooled dressings. It features a boarded timber door offset to the left of center and flanking single windows, a grey slate roof with small rooflights, and a pantile roof on a timber addition to the right.

The potting shed to the northeast is also single-storey and mono-pitched, constructed of red brick with boarded timber doors and small-pane windows. It has a gabled greenhouse attached to the left and a mono-pitched projection on the outer left. The right side has a grey slate roof, while the outer left uses modern roofing material.

The outer garden is a narrow, near rectangular-plan space adjoining the western corner, surrounded by tall, predominantly harl-pointed rubble walls, with a red brick inner lining in the northeast corner and no wall on the southwest side. Modern gates provide access.
