The Historical Sandstone Building, that was once the Old Seton Hall Law School building, located adjacent to the Gateway I Center building and the Prudential Center Arena, is proposed to receive 5 additional stories of Luxury Condominium space above the existing 8 stories of prime office space. There will also be an expansion over the existing parking lot, which will consist of 4 levels of stackable parking and 4 levels of additional rentable office space.
