Fourteen years after achieving statehood in 1890, the State of Wyoming built its first governor's mansion in 1904. The state purchased a vacant corner lot from the private sector, in an established middle class neighborhood, six blocks from the State Capitol. The house was modern in most respects because it had central plumbing, hot water heat, and combination gas and electrical fixtures throughout. The solid sandstone columns of the portico were quarried locally in four sections and then placed one on top of the other. The top half of the columns are fluted. The Corinthian style capitals were carved on site. During the seventy-one years of occupancy the mansion was never enclosed by a fence and never had on site security. From 1905 to 1976, the Mansion was the residence of 19 Wyoming First Families.

Dubbe-Moulder Architects provided historic architectural services for the interior and exterior restoration plan of the Historic Governors' Mansion and Carriage House, and and prepared construction documents.
