The barn has also been restored and the outbuildings rebuilt. The New England style side-hill barn now houses horses and cattle. Oats and wheat are stored in the barn's granary and hay and straw are stacked in the bays. The pigs and sheep are housed in their own sheds, the poultry in a period chicken coop. A machine shed holds the plows and implements and corn dries in the corncrib. All of these "plan book" farm buildings are built to patterns from the 1850s with period hardware and construction techniques.

Kelley Farm guides plant corn with a hand stab corn planter. The Interpretive Center is in the background. Built in 1981, the center houses a museum book store and interpretive displays about the Kelleys and the Grange.
