This Greek Revival–style house was constructed for the Strunks, who had moved from upstate New York to Janesville in 1839. Smoothly dressed, locally quarried limestone blocks, twenty inches thick, form the walls of the one-and-a-half-story house and, at the corners, quoins project slightly from the planes of the walls. Beneath the eaves of the side-gabled roof, very short attic windows allow light into the upstairs rooms. Breaking the formal symmetry of the composition is a one-story wing with an inset Doric loggia. A glazed solarium has been added to the rear of the wing. John Strunk died the year the house was finished, leaving Eleanor with five children. For forty years she oversaw the operation of their thousand-acre farm, which extended from the Rock River to what is now Milton Avenue.
