This two-story addition was made of hand hewn stones quarried in the South Park area and was added to the original log house in 1808 by Miller's son, James.

A model of how the 1808 building would have looked, constructed by member Art Farley, will be on display. There will also be displays focusing on the methods and tools used for building construction in that era. Information will be available in the barn on conditions in the nation, the Pittsburgh area and the area of Mansfield during that time period.

Associates, in period dress, will conduct tours of the stone house, springhouse, log house, forge, and barn, and present ongoing demonstrations of spinning, weaving, quilting, open hearth cooking and blacksmith work. Books, trade goods and items made at the Homestead will also be for sale at the Trading Post.

Hours are 1:30 to 4:30 p.m. Sundays, May 4 through December 14, with the last admission at 4 p.m. Minimal admission charge.
