Former Granary at Headstone Manor

The Former Granary at Headstone Manor is a building likely constructed in the late 18th century or early 19th century. It was adapted for use as a museum visitor centre after being relocated in 1990-91.

The structure features a square plan with three storeys, each with four bays on every elevation. The ground floor is made of brick laid in Flemish bond, while the upper storeys are framed in softwood timber and clad in weatherboarding, which is a modern replacement. The pitched roof is covered with slate. Each upper floor has four windows on each side, with an additional window in each gable. The ground floor has four windows on each side and three windows along with a doorway in the gable ends. All windows are set in square-headed openings, equipped with modern secondary glazing, and most still have their vertical iron security bars. The windows feature simple timber drip boards, except for the top row, which is protected by the overhanging eaves or slightly projecting gables. Internally, the windows are fitted with top-hung wooden shutters, and the timber door frames hold plank and batten doors with internal round-end strap hinges.

Inside, the roof is supported by five softwood queen post trusses, with straight bracing below the tie beam on those forming the gable wall. Other tie beams are reinforced with cast iron brackets secured by iron pegs. Most roofing elements and the studding and bracing on the second floor are original, although the second floor itself has been removed, leaving the joists intact. The principal beams at the first floor level are original, but many of the posts, studding, and bracing have been replaced. All grain chutes and bin partitions have been lost. The ground floor beams, which are supported on brick piers with replacement timber wall plates, are mostly original, as are the joists, though the posts have been replaced. A modern timber closed string stair is located in the northern corner, and the floor is finished with modern concrete tiles.
