The Mary Brown House was built in 1885 in downtown Marinette, overlooking the Menominee River. This house was a gift from Mary’s father, local lumber baron and later United States Senator, Isaac Stephenson. Originally constructed in the Queen Anne style, the house received an extensive Tudor Revival makeover beginning around 1920 and was completed no later than 1935. The Tudor Revival style was used for a large portion of early 20th-century suburban houses throughout the country and was particularly fashionable in Wisconsin during the 1920s and early 1930s.

Tudor Revival architecture was at the peak of its popularity when the Mary Brown House was transformed stylistically from a Queen Anne to a Tudor Revival. The house displays distinct characteristics of the style, such as front-facing gable, overlapping gables, varied eave-line heights, stucco cladding, false half-timbering on the second story, and grouped multi-light windows. All other Tudor Revival houses in the City of Marinette are smaller and less detailed, reflecting the “Cotswold Cottage” form of the style.
