One of his first commissions was a Dutch/gothic style residence on Federal Ave in Seattle that was the home for several decades of Teddy Roosevelt's granddaughter.

Their work included residences, churches, schools, hospitals, memorials, club houses, commercial structures and other buildings.

The firms work was stylistically eclectic, reflecting Gould's Beaux-Arts training and the tendencies of the period.

[3] Gould contributed to the U.S. effort in World War I, by designing a 3,000-worker community in Washington as a company town supporting the Spruce Production Division.

(The design of the front elevation reflects the influence of draftsman Walter Wurdeman who had joined Bebb and Gould after graduating from the University of Washington.)

[6] Works by Gould or by his partnership include many that survive and/or are listed on the U.S. National Register of Historic Places (NRHP).

[citation needed] Overall, Carl F. Gould was a key figure in architecture and the arts in Seattle in the first four decades of the twentieth century.

[citation needed] In 1941 his daughter, Anne Westbrook Gould, married John Henry Hauberg Jr.[9] The family papers are archived at the University of Washington.
