Stonehall is one of Michigan's finest examples of Greek Revival in combination with the vernacular tradition. The latter is especially evident in the pentastyle (five-columned) Doric portico, for an odd number of columns is not at all characteristic of the architecture of ancient Greece. The only entrance to the home, on the east side, has a transom and sidelights and is set off by a small extended porch with a pair of Doric pilasters and columns. The house is built of locally quarried, yellowish Marshall sandstone. Dr. Andrew L. Hayes (1801–1864) built the house six years after he came here from New Hampshire. Marshall's first physician, Hayes was also a planter and a land speculator. With advice from Young, Lewis E. Brooks (1880–1958), brother of Harold C. Brooks, restored it.
