Designed by architect Frederick Atkinson and constructed in 1903, the building was erected during the first great wave of apartment house construction in Washington and is representative of the era circa 1890-1917, in which the apartment house was popularized in America; the Plymouth is symbolic of the crucial middle-class approval needed for the apartment house form to survive in Washington. The significance of the building is heightened by the increasing scarcity of Washington apartment houses of this style. The Plymouth's importance also derives from its exceptional architectural integrity, making the building a fine example of the Neo-Classical Style as it was applied to the apartment house form.
