The iconic house in the sitcom "Full House" has two staircases that lead to the same point upstairs, but only one is visible upstairs, which confuses fans. The set also lacks an attic despite the series showing Becky and Jesse living in it. The living room has no seating arrangement, and there is no driveway despite multiple drivers living there. The house's layout is unusual because it is a set, but it has some additional problems besides the staircase. Despite these flaws, "Full House" remains a beloved sitcom with memorable storylines and characters that are still relevant today.
