Description
Great Moonshine Farm is a barn and granary that has been converted into a private house. Originally built in the 16th century, it was transformed into a residence in 1982. The structure features timber frames resting on red brick sills, with flint panels in a deep sill on the south side of the barn. It is clad in dark weatherboarding and topped with a steeply pitched handmade red tile roof.
An eastern wing made of red brick on the ground floor is complemented by dark weatherboarding above and a matching tiled roof. There is a west link to the granary, which now serves as a billiard room, featuring a high flint-panelled sill and a low dark weatherboarded wall on the west side, supported by posts and with a glazed front facing the courtyard. A lean-to passage has been added along the north side of the barn, covered by a catslide roof.
To the east, there is a linked half-hipped brick garage and a hipped projecting glazed porch at the eastern end of the barn. The property forms a three-sided courtyard that opens to the south, with the former barn making up the northern range. The barn consists of seven bays, characterized by jowled posts, curved braces to the tie-beams, and a clasped-purlin roof supported by collar and queen-strut trusses, along with curved wind braces to the purlins.
The granary, located at the southern end of the western range, is now open to the roof after the insertion of a floor on heavy chamfered beams was removed around 1982. It comprises two bays with massive jowled posts, curved braces to a cambered tie-beam, mid-height rails aligned, and a clasped-purlin roof with queen-strut and collar trusses, as well as heavy wall studs. There are mortices indicating a central partition. The farm was referred to as 'Munchions Farm' on the Tithe Map of 1838.
