It has a complex facade, divided into seven sections, with a central projecting section topped by a tower with a coppered onion dome. Matching sections at the center sections of the three on either side are articulated by piers and topped by gabled parapets. The building houses stores on the first floor and offices on the upper floors. The block was listed on the National Register of Historic Places in 1982.
