A largely self-educated poet, artist and craftsman, Moon built over 260 structures, most of them in the area of Lansing and East Lansing, Michigan, during a prolific career that stretched from 1860 to 1923.

[1] His Queen Anne-style houses range from the Ransom E. Olds residence (demolished in 1971 to make way for the R. E. Olds Freeway) to the Howland House student co-op (originally the home of Chester D. Woodbury) in East Lansing.

He also designed residences for Henry Kosltchek, Edward D. Sparrow, Frank Dodge, Judge Person, and H.M. Rogers.

In addition to houses, Moon designed four schools, the Olds Motor Works, and the original Sparrow Hospital.
