An old factory at 80 Richards Street in Red Hook will soon become an office building with possible commercial space, according to brokers marketing the property. The massive six-story building has 50,000 square feet on the ground floor and 20,000 on each of the upper floors, and a rooftop that could become a cafe. An outfit called HH Equities bought the 134,000-square-foot factory in 2003 for $9,000,000, according to PropertyShark. The owners are offering a variety of concessions to attract potential tenants, including one year free rent, building the space to suit, etc. Commercial Acquisitions Realty, which is marketing the building for lease, tells us the owners hope to host “business corporations, young entrepreneurs, artists and fashion and media companies.” Construction is expected to begin in the next month.
