Hull Building, Historic commercial building in Belltown, Seattle, United States

The Hull Building is a three-story brick commercial building at 2401-2405 1st Avenue in Seattle's Belltown neighborhood. Designed by architect Elmer Fisher, it has a restrained Victorian motif with exposed corbelled brick, pressed tin trimmings and cast iron storefront columns. Three store rooms face First Avenue, and the upper floors once held working-class apartments.

Alonzo Hull, a Pennsylvania-born Civil War veteran and Seattle city councilman, bought this lot at 1st Avenue and Battery Street in February 1889 for $13,000 from Dr. Edward C. Kilbourne. At Kilbourne's urging he hired architect Elmer Fisher, and the $30,000 brick building was finished in January 1890, one of Belltown's first substantial brick structures. The Eng family owned it from 1958, running A-1 Laundry here for 58 years until 2016.

The building shows how commerce and trade operated in late 19th century Washington through its physical design and layout. Visitors can see in the facade and structure what materials and construction methods were typical of that era.

The building can be viewed from the outside and clearly displays its appearance and original structure. The best time for photographs is during daylight when the facade details are clearly visible.

The building's cornices were replaced at some point with near replicas, but otherwise it has had minimal restoration work. Its upper floors fell vacant as commercial development in Belltown slowed after the early 20th century and have remained so.
