The Sibley Building in Rochester, N.Y.–once the largest department store between New York City and Chicago–is being reborn as Sibley Square. Boston-based WinnDevelopment is renovating the 1-million sq. ft. property with a variety of financial sources, including equity from low-income housing tax credits (LIHTCs), new markets tax credits (NMTCs) and federal and state historic tax credits (HTCs).
