Stowe Barton, Outbuildings Adjoining at North and West and Wall Adjoining at South

The farm building, dating to the 18th century, is constructed of slatestone rubble with polyphant ashlar and local brick dressings, and has slate roofs. Brick chimneys are located at the gable ends and at the rear. The main two-storey range is a single depth, with a rear right lean-to that is partly raised to two storeys. A rear kitchen wing, under a gabled slate roof, forms a T-shaped plan. An outbuilding with a lower hipped slate roof adjoins the left gable end of the main range and incorporates first-floor house accommodation.

A slightly off-centre gabled stone porch was added in the late 19th century. The porch has a cornice supported by four granite monolith columns, likely reused, with roll mouldings at the base of the outer columns. A stone cartouche bearing the Grenville arms sits below a Sun Fire Insurance sign in the porch gable, above a six-panel entrance door and a rectangular fanlight. The front windows are casements with six panes per light, the ground floor windows having dressed polyphant architraves. A three-light casement occupies the ground floor left, while a hall window to the left of the porch comprises a one two-light, one three-light, and one two-light casement with a common architrave. A similar window to the right of the porch has outer casements blocked. A larger three-light casement is on the ground floor right. First-floor windows are set within flat local brick arches; there are five in total: three-light, three-light, two-light, three-light, and three-light.

The hall has a Delabole slate floor and a large polyphant ashlar fireplace with a segmental arch springing from imposts with square-section abaci. Folding shutters are fitted to the casements. A ground floor room on the right has a 19th-century fireplace with soft wood panels inset with gesso decoration, folding shutters, and a deep bolection-moulded skirting board. The outbuilding adjoining the west side has a cobbled floor, a beam for a cider press, and a sawpit. First-floor partition walls in the outbuilding are constructed with studwork and local brick nogging, with halved and pegged roof principals. Adjacent to the north, there are stables with a loft, built of slatestone rubble with a gabled slate roof and an external stone staircase to the loft at the north gable end. The stable has a cobbled floor, timber partitions, and timber mangers. Some casements, reused from the farmhouse, are in the loft and stable. A lean-to piggery adjoining the north wall contains six entrances, bolted slate compartments, and wooden troughs and mangers.

A ramping English bond brick garden wall with brick coping runs along the south side of Stowe Barton and is likely part of the gardens of Stowe; it is included within the listing for group value. Stowe Barton is understood to have been erected in 1739, following the dismantling of the old service quarters at Stowe. The site is on or close to where the stables at Stowe once stood; Stowe itself was built in 1679 and demolished in 1739.
