Joseph Jossen House, historic house in Mobile, Alabama, United States

The Joseph Jossen House is a brick residence built in 1906 in Mobile, Alabama, displaying Queen Anne style with decorative details and an asymmetrical roofline. The two-and-a-half-story structure was later expanded with a two-story stucco addition at the rear and adapted for commercial use.

The house was constructed in 1906 for Joseph Jossen, a local representative of the F. W. Cook Brewing Company operating in Mobile since 1884. It was added to the National Register of Historic Places in 1992 in recognition of its historical importance and architectural quality.

The house is named for Joseph Jossen, the F. W. Cook Brewing Company agent who opened the brewery's Mobile distribution branch at 19 South Commerce Street in 1884 and also traded in liquor. The building later served as the city's international trade center, which is why it became known as the World Trade Building.

The house stands in downtown Mobile, Alabama, at coordinates 30.69306, -88.04417. It is a private building occupied by a title insurance company as of 2009, so visitors should view it from the street rather than expect interior access. Its National Register listing dates from May 29, 1992.

The building was later transformed into the World Trade Building serving the international commerce industry, with the original front porch enclosed and a modern stucco addition added to the rear. These changes demonstrate how historic structures could adapt to new economic purposes while retaining their original architectural character.
