Range of four barns, fowl house and cow houses approximately 60 metres to north west of Harnage Grange

A range of four barns, a fowl house, and cow houses dating to the mid to late 17th century, with later 19th-century alterations, are located approximately 60 metres north west of Harnage Grange. They form part of a larger farm complex around two square farmyards. The buildings enclose three sides of a square farmyard, with former stables forming the east side.

The south range is timber framed with red brick nogging on coursed sandstone rubble, a 19th-century brick plinth, and a weatherboarded gable end to the west. Portions have been rebuilt in coursed grey sandstone rubble and red brick, all under plain tile roofs. It includes six framed bays and one storey with a loft to the west. The framing features tall, wide panels with a middle rail, short straight corner braces, and one long straight tension brace. The north front has boarded loft doors, late 19th-century slatted and fixed glazed windows, and two-leaf boarded doors to the left and right. A left-hand return front includes an external flight of ten stone and brick steps leading to a boarded loft door, and a triangular wooden dovecote in the gable end. Inside, the roof structure comprises collar and tie-beam trusses with queen struts and pairs of purlins.

The west range, also dating to the mid to late 17th century, is timber framed with red brick nogging to the east and weatherboarded to the west, with plain tile roofs of differing heights. The south barn has three framed bays, and the north barn has four. Framing features square panels with long straight tension braces. The east front has irregular openings and cart entrances to the left and right. Internally, storage bays have cross frames with sole-plates on low dividing walls, long straight tension braces, and central posts. The roof structure includes collar and tie-beam trusses with queen struts and pairs of purlins with windbraces.

The north range, also from the mid to late 17th century, has mid to late 19th-century alterations. It is timber framed with red brick nogging to the north and weatherboarded to the east and south over a 19th-century red brick ground floor. It has one storey and a loft. Framing features square panels with long straight tension braces, with the top panel possibly an addition; scotches are also present. The south front has three boarded loft doors, two segmental-headed two-leaf boarded cow house doors, two segmental-headed wooden casements, and a through carriageway to the left.
