This is partly why the second option was selected, much more conventional despite its unique qualities. Nicknamed the Pantheon, it mimicked the Roman structure in the dome’s function. The enclosed structure was to receive a an oval diaphragm-inspired retractable roof. Created with 8 straight-moving petals, the roof would have been the first of its kind.
Just a year after this selection, in May 2014, actual construction began on the site just south of Georgia Dome. The dome’s successor was to receive somewhat smaller capacity (71,000 instead of 74,000) but much greater footprint and floor space. This of course means a different seating layout, one that includes both much more legroom and more hospitality and a huge, 16-floor ETFE-covered ‘window’ in the eastern part, giving fans a view of downtown Atlanta.
The general public will take much of two large tiers which are divided by two balconies with skyboxes and premium seating. While this is far from the end of corporate hospitality options, the stadium does include one particularly interesting feature: a wing-shaped single tier in the east that includes some of the Falcons symbolism. For regular NFL games the stands hold 71,000 people, while in MLS layout the nominal size will be 32,500. In Super Bowl layout the ground would grow to 75,000 (first time in 2019), while for NCAA basketball the size could exceed 83,000.
