Wilson Chapman editorThere have been plenty of television shows set in workplaces, but there’s never been one that looks quite like “Severance.” The Apple TV Plus science fiction series is set in the headquarters of Lumon Industries, a mysterious, cult-like company that surgically alters the memories of select employees to split their consciousness in two: their work selves and their outside selves. These “severed” employees work on their own floor in the company building, and it’s a world in itself: a sprawling labyrinth of stark white halls that stretch into eternity, and massive, void-like office rooms with eye-catching green carpeting.Production designer Jeremy Hindle drew from a wide array of sources when crafting the sets of the series, from the 1967 French film “Playground” to the aesthetics of pharmaceutical companies.
