Agricultural Complex at Garn

This is an agricultural complex comprising two long barns arranged at right angles to one another, with a former carthouse block adjoining at the north corner, forming a Z-shaped layout. The buildings are primarily constructed of limestone rubble with slated roofs, though the main southwest range has a more modern corrugated metal roof. The southwest range's southeast gable features a kneelered rubble parapet. This range has irregular openings, including a boarded entrance and a vertically-slatted window. Further windows are present, with two featuring modern glazing and one slatted. The upper floor has five windows, three and five from the left having segmental arches. A long flight of stone steps leads to the upper loft entrance, which breaks the eaves; above this entrance is a gabled dormer with plain bargeboards.

The adjoining range has a large central barn entrance flanked by a tall, four-pane sash window from the late 19th century and a vent slit with a window beyond, the latter with six-pane fixed modern glazing. To the right of the large entrance is a two-part, eight-pane 19th-century window, with a twelve-pane sash above the lower boarded section. A tall boarded loading door is followed by a six-pane window. A later addition forms the end bay, recessed slightly but continuously roofed with the main range; this section has a boarded door, a three-part window, and a 19th-century twelve-pane sash above. A boarded loft door is located in the gable end, accessible via a surrounding stone stair with a metal rail; a projecting chimney breast is also present on the gable end. A decorative wrought iron weather vane sits atop the roof, with the main section bearing the date 1746 and a restoration date of 1982 on the rear section. Two large lean-to cart bays and a large 20th-century lean-to adjoin the rear of this range.

The carthouse block, adjoining at the north corner, has a flight of stone steps leading to a boarded loft door on its southeast gable. The northeast side has two reduced cart bays with exposed timber lintels and boarded doors, set within brick and rubble infill. A window with vertical slatting and a three-pane upper section is to the right, followed by a boarded door and a matching window.

Inside the primary barn (southwest range), the interior has a four-bay layout with low pegged collar trusses, likely dating to the 1740s. The second range exhibits a five-bay roof with reused, pegged tie-beam trusses, featuring broad curved braces and a queen post truss at the southwest end.
