The stadium is designed by American architect Dan Meis, who has drawn up the plans for numerous stadiums and arenas in the United States, plus the Saitama Super Arena in Japan.
"It's impossible designing a building here without considering the architectural history in Rome," Meis said. "The stadium will have an outer wall that will be a new vision of the Colosseum."
There would be a three-tiered seating design with a sharp incline, and a 14,000-seat detached section behind one of the goals for the hard-core fans, replacing Olimpico's Cruva Sud.
There also would be luxury boxes and commercial areas, plus training facilities outside the stadium.
Roma would become only the second major Italian club to own its own stadium. Juventus, which is closing in on its third successive title, opened Juventus Stadium in 2011.
