As he grew older, his eyes became damaged by the strain of smithing, so he and his wife Elizabeth purchased property on South Meridian Street[2]: 3  in northern Perry Township,[2]: 5  which was then known as Three Notch Road.

Here they built a log cabin and began farming; as they prospered, they prepared to erect a brick house, but construction was delayed nearly ten years by the American Civil War.

[2]: 3 The Stumpf House is a symmetrical two-story brick structure with a foundation of fieldstone; except for a small addition to the rear that consists of a porch and kitchen, it is rectangular in layout.

Measuring five bays wide, the facade includes shorter attic windows, a recessed entrance with a heavy wooden front door, and two large chimneys.

It is one of five National Register-listed locations in Perry Township, along with the main administration building of the University of Indianapolis, the Hanna-Ochler-Elder House, the Homecroft Historic District, and the Old Southport High School.
