The Gural family is planning to reconfigure and make upgrades to their six-story, 122,454 square-foot commercial property at 560 Broadway, in SoHo, according to Crain’s. The building, built in 1890 and located within the SoHo-Cast Iron Historic District, will have its main entrance moved to Crosby Street. In the process, Converse – one of two ground-floor retail tenants – will gain 1,500 square feet of space and 30 feet of street frontage. In addition, two of the building’s four stairwells will be removed in exchange for elevators and 8,000 square feet of extra office space. The Landmarks Preservation Commission would have to approve the project, which would also rename the building to 100 Crosby Street. Rosen Johnson Architects is designing.
