In August of 1920 Nichols turned his concentrated attention to the 400 block of 21st. One of the first homes carved from the treeless streetscape was this two-story bungalow, sold to attorney Frank A. Rittenhouse in 1921. A native of Nebraska, Rittenhouse had moved to Oklahoma territory in 1904, but returned to the University of Missouri where he completed work on the law degree. For a few years he lived in Chandler, then moved to Oklahoma City in 1921. Rittenhouse, his wife, Alma, and their two children lived in the home until 1949. Since then, like most of the homes in the neighborhood, the bungalow has been steadily updated and modified to conform to changing technology and lifestyles.

The second owners, Margôt and Charles Nesbitt, had a large family, so they added a club room and wood burning fireplace on the rear, enclosed the sleeping porch and made it part of the master bedroom, replaced the front porch, and built a small patio on the east side. In 1968, the Rev. and Mrs. Neil C. Winslow purchased the home and continued the modernization with central hear and air, another wood burning fireplace, a new kitchen, and all new plumbing. While retaining the architectural integrity of the exterior, these two families adapted an old house to new demands.
