This structure is a careful copy from existing sixteenth-century buildings and including details like the windows with half-wooden shutters and half-leaded glass. The overall design and decorative but usable gun loops are copied from the gatehouse built at Tolquhon Castle, Aberdeenshire built in the 1580s.
