Linen closet - Gather all your cleaning and interior home upkeep supplies into ONE location, like a small coat closet. Coats can be moved to coat hooks/racks in the entry to free up this premium storage space.
Otherwise, you're absolutely free to decide on a shape that is suitable for snugly in your living room space. Nobody will even know that you're employing the room divider to hide clutter. Somebody does not require a spare room to turn it into a playroom.
