the felsenthal store, apartment, office and loft building was designed and built by louis h. sullivan in 1906 for eli e. felsenthal (friend and family attorney for sullivan's former partner, dankmar adler). the two-story masonry building was located at 701-709 east 47th street, chicago, ills. 

the project marked the transition in sullivan's practice from tall commercial skyscraper buildings to the heavily ornamented low-rise structures erected during the later part of his career.
