Farm Buildings Immediately West of Riviere Farmhouse

The farm buildings immediately west of Riviere Farmhouse are a group of structures that include stables, a cartshed, shippons, an engine house, granaries, and fodder stores in the lofts. These buildings were originally constructed in the mid-19th century for the Cornish Copper Company to accommodate pack-mules and horses. They are built from granite rubble, copper slag blocks, and granite dressings, featuring hipped grouted scantle slate roofs, with some areas covered in corrugated sheeting.

The layout of the buildings is irregular and resembles an inverted F-shape, with two small wings at right angles to the rear. The two-storey section is L-shaped and adjoins bank barns, with the left front wing built into a high bank and the larger main barn at the rear also built into a bank. The remainder of the buildings are single storey, including the engine house at the rear middle, a swill kitchen at the rear right, the cartshed at the front left, and stables at the front right, along with an L-shaped stable and cartshed at the far right.

The exterior features regular elevations with original doorway and window openings. The main barn has a two-storey front and a ground floor doorway with loading doorways above, along with regularly spaced window openings. Another front has three ground floor doorways, with the left-hand part presenting a symmetrical three-window front and a central doorway. Most doors are ledged, with shuttered windows on the ground floor and two-light windows on the first floor, all equipped with top light ventilators. While many original fittings have been removed from the interior, the floors and roof structures remain intact.
