The Long Barn and attached courtyard wall, gates and railings

The Long Barn and attached courtyard wall, gates, and railings is a long stable range built in the 18th century, now divided into three dwellings and extended to the west. Constructed of stone with stuccoed cladding, it features a Welsh slate roof with half-hips. The building is single storey and loft to the east, extending to two storeys at the west. The main facade faces north and has cambered arched openings on the ground floor, with 8/8 pane casement windows or louvres directly under the eaves above.

The eastern unit, which was formerly stables with a hayloft, includes a range of four louvres for the former loft, four louvred ventilators with finials on the roof, four ground floor casements, and a central round-arched doorway. To the right is a former tack room with a separate doorway and a single window on each floor. The central unit, which was the former coach house, features two adjacent coach entrances, a double entrance to the right, and a single doorway at the end right, with three casement windows above. The end unit on the right, known as The Cottage, was the former coachman's residence and has a central round-arched doorway flanked by windows, with three windows above, the central one being a narrow six-pane window. Bolted ties are visible below the eaves.

At the northwest end, there is a high section of the former courtyard wall made of limewashed rubble with flat stone coping, which returns on higher ground to form a low boundary wall with replaced entrance gates and railings, along with piers at each end, relating to its former function as an approach from New House. The rear of the main building features an asymmetrical range of mostly casement windows, two lateral stacks, and added roof lights.

The interior has been converted into three dwellings, and the woodwork of the A-frame roof trusses is reported to be made of red oak and numbered, with some timbers appearing to be reused.
