“Squid Game: The Challenge” was filmed almost entirely in the UK, mainly at Wharf Studios in Barking, East London, with the huge “Red Light, Green Light” game shot separately at Cardington Studios in Bedford.

Main filming location

Most of the reality series was produced at Wharf Studios in Barking, in East London.

  • Production used all six interconnected sound stages to recreate the dorms, games, and other sets seen in the show.
  • The giant bunk bed hall where contestants sleep and many of the indoor games were built and filmed here over an intensive 16‑day shoot.

The “Red Light, Green Light” arena

The massive “Red Light, Green Light” game needed a much larger space than Wharf Studios could provide.

  • That game was filmed at Cardington Studios in Bedford, a former aircraft hangar and one of Europe’s largest indoor filming spaces.
  • The game set reportedly spanned around 100 meters by 40 meters inside the hangar to accommodate all 456 players at once.

Quick scoop style recap

  • Main base: Wharf Studios, Barking, East London (sets, dorms, most games).
  • Oversized game: Cardington Studios, Bedford, for “Red Light, Green Light.”
  • Both locations are purpose‑built or converted studio spaces commonly used for big films and TV, which helped Netflix recreate the original “Squid Game” look in a controlled setting.
