what harmless feature would make a shed unnecessarily fun?
not a hidden room or anything that turns it into a movie villain's hideout.
i mean a small, completely unnecessary feature that makes the building more enjoyable. a tiny observation window under the roof, a ridiculous hidden compartment, a built-in speaking tube, a sliding panel that reveals a shelf
something that serves almost no practical purpose but would make people smile when they discover it
what would you add?
