"Victorian" has been used after the fact for styles in Western culture even when referring to those in France or America, because they constantly influenced each other. At the time, someone might name their style of carriage "a Victoria" but no one called a style of architecture Victorian. At the time it might be called Classical Revival, Gothic Revival (often the fonts we call medieval are 19th C Gothic revival), Beaux Arts, Italianate, Eastlake, Arts & Crafts (tho' American & British A&C were very different), Art Nouveau, &c. There were revivals like the Queen Anne style, more in spirit than with great authenticity.

In the United States, Victorian house styles include Second Empire, Queen Anne, Stick (and Eastlake Stick), Shingle, Richardsonian Romanesque, and others.

Although the general public often incorrectly refers to a Victorian-era house as a Victorian-style house, Victorian era refers to a time period and not to a style.
