The fifth proposed stadium for the 2022 FIFA World Cup in Qatar, Al Rayyan Stadium, has been released by Qatar’s Supreme Committee for Delivery & Legacy, ArchDaily reports. London-based Pattern Architects is the team behind the design. Al Rayyan Stadium seats 40,000 spectators, and much of the material to build it will be scavenged from the former Ahmed Bin Ali Stadium, which will be demolished to make way for Al Rayyan.
