WinnDevelopment could close on the Sibley building next month. Chris Fleming, senior project director with the Boston-based company said Monday that the closing could happen in the second half of August. | Fleming said the historic building would be converted to mixed use with retail on the first and second floors, office space on floors three to six, and housing on floors seven to 12 — the Sibley Tower. | Fleming would not disclose the sale price. He also said he doesn't have a "full answer" to what will happen with the debt owed on the Sibley building. RochWil Associates, a subsidiary of Wilmorite and current owner of Sibley, owes the City of Rochester millions of dollars. RochWil's unwillingness to pay up irks a lot of people in the community. | Notably absent from WinnDevelopment's plan for the building is Monroe Community College. MCC occupies two floors in Sibley and recently signed a new five-year lease. | "They've announced that they want to move to the Kodak building," Fleming said, "so we're assuming that's going to be the case. If for some reason they were to change their mind on that, we'd be more than happy to welcome them to stay."
