The ?Barn on Lot 8, Range G? is an English style barn modified in plan to provide for additional livestock, equipment and feed storage. Built circa 1825, the older part of this two-section barn exhibits a hewn timber frame, complex joinery fastened with pegs, and a traditional three-bay plan with center aisle.
