Big Ben is a giant decorative wall clock based on the ornate clock face of the famous landmark, which was recently renamed the Elizabeth Tower.
"Clocks are by now probably the most non-functional object," said Wanders, suggesting how easy it is to find out the time from our phones, watches and computer screens.
"Because [the clock] doesn't have any function anymore, it has a very decorative aspect," he told Dezeen.
