Barn approximately 50 metres north of Clacton Grove House

This is a former threshing barn, likely dating from the early 19th century or earlier. It is constructed with a timber frame, clad in weatherboard, with some rendered areas, and has a roof covered in corrugated-iron sheeting.

The barn is a large structure of seven bays, with two asymmetrical, gabled midstreys projecting to the south. The timber-framed barn sits on a five-course plinth of 18th-century red bricks generally laid in stretcher bond, with 20th-century patching in Flemish bond; the plinth is higher on the south elevation. The wide, feather-edged weatherboard cladding is exposed at the west gable end and front elevations. The double doors to the midstreys rest on a plinth likely indicating that carts were drawn up to the entrances for loading and unloading. A planked pedestrian door and a taking-in door are situated in the west elevation's ground floor and apex respectively, both fitted with strap hinges. The rear elevation includes two vehicular entrances with double doors, corresponding to the midstreys, which have been heightened, causing a localised alteration to the roof structure. Two window openings have been inserted into the rear elevation between these doors. The rendered east gable end features a window at the apex and a planked pedestrian door with strap hinges at ground floor level, near the front corner. The roof is covered with narrow-furrowed corrugated-iron sheeting.

The interior timber is generally of good quality with limited evidence of reuse, although some hewn branches are incorporated into the frame. The wall and cross framing is substantial, jointed and pegged, comprising wall posts, wall and sole plates, and close studding with diagonal straight bracing. Tie beams are present, some with added bolted and shaped knee braces, others with metal strapping. One tie beam, some straight bracing, and a portion of the sole plate in the south wall frame have been replaced. Corrugated-iron sheeting is attached to the lower part of the south wall frame between the midstreys. A timber runner, possibly for a later partition or hopper, is nailed to a wall post between the midstreys on the south wall frame, representing a later addition. The roof features coupled rafters with clasped purlins, collars, and ridge pieces; some of the collars are machine-sawn planks. The narrow battens supporting the corrugated-iron appear to be later.

The midstreys incorporate midrails, additional bolted or nailed straight corner braces at the entrances, and some interior weatherboard cladding. Both have coupled rafter roofs with side purlins and ridge pieces. The west midstrey has an in-situ loft platform at the gable apex, with additional beams inserted later just above midrail height. Remnants of raised threshing floors are visible to the rear of the midstreys.
