Steelworks Lofts on North Fourth Street in Williamsburg is a 130,000-square-foot condominium project designed by AvroKO. It’s the firm’s first residential project and contemplates the adaptive reuse of industrial space that was formerly the headquarters of Lewis Steel Products back in the 1930s. Developer Fifth Square Partners is aiming to reclaim and repurpose as many materials as possible in connection with construction. It has also retained New York-based Greener By Design to landscape an 8500-square-foot green roof. David Berger, co-founder of Fifth Square, called the project “green design at its simplest,” though it’s unclear what additional green features or third-party certification (if any) the project will pursue. Gene Kaufman Architect, P.C. is the architect of record and residences will range from 640 to 1683 square feet. The project should be completed in time for a spring 2010 occupancy.
