The Haffen Building is a seven-story Beaux-Arts style office building designed by architect Michael J. Garvin and erected in 1901 to 1902 by brewery owner Mathias Haffen. The building is located in the western Bronx neighborhood of Melrose, an area predominantly populated by GermanAmericans during the 19th and early 20th centuries. The Haffen Building was part of the rapid development of the “the Hub,” the commercial center of Melrose, which centered on the intersection of East 149th Street, Melrose, Willis and Third Avenues. By the turn of the 20th century, the Haffen family was one of the main families of the Bronx, having made essential contributions to the physical and social infrastructure of the Bronx including surveying and laying out of parks and the streets, developing real estate, and organizing of a number of civic, social, and financial institutions.
