A new 14,000-seat Louis Armstrong Stadium will open for the 2018 US Open. This new stadium will also have a retractable roof, the largest of its kind among the No. 2 stadiums at the Grand Slams. On each side of the stadium there will be façades that are covered with terra cotta louvers, optimally positioned to keep rain out, yet porous to maintain natural ventilation. Designers say the terra cotta material contextually relates to the traditional brick buildings on the site while using the material in a new way. For the 2017 tournament, while construction is still ongoing on the new Louis Armstrong Stadium, a temporary 8,800-seat stadium was built on the site of the demolished ticket office and East Gate entrance, on Parking Lot B, close to the boardwalk ramp to the subway and LIRR trains.
