The Charles O. Boynton House is located in the DeKalb County, Illinois, city of Sycamore.

Boynton owned farmland in DeKalb County as well as almost 75,000 acres (300 km2) in Iowa, Kansas, Minnesota, North and South Dakota, and Arkansas.

His hand picked architect was George O. Garnsey of Chicago, who had designed a number of prominent structures in DeKalb and in Sycamore.

Even in the home's last years with Lillian Boynton the ballroom still retained its deteriorated original wallpaper and gas chandeliers.

Both the home and carriage house passed hands, separately this time, due to bankruptcy proceedings.

Authorities speculated that a carpenter's van owned by a hardwood flooring company that was working on the property ignited, causing an estimated $175,000 in damages.

The porte-cochere has been remodeled over the years and was originally intended to awe and amaze visitors to the Boynton House.

The 1940s brought the commercial conversion of the first floor of the home and the porch was enclosed with glass to provide additional space for the business.
