The barn is the only remaining building of the former home farm of Harpsden Court and stands next to the church. It is weatherboarded, of three bays with a brick stable extension on the west side. Both are now converted to residential. The most interesting feature of the barn is the carved initials and dates of the owners, Henry and Elizabeth Hall ( H, H16 & E89), on the doorposts and lintel. The same, plus a tulip head, are repeated on the tie beam adjoining the threshing floor. The roof structure is of the queen strut and clasped purlin type
