Whats the dumbest thing someone in your family ever build?

My dad always renovate or improve house by himself. He's not an expert and not a fan of tidiness, you know the outcome

They never gave me a key to the house. Like explicitly made a point to never give me a key and I had to be out of the house if they were gone. So there I am, parents gone, and I can't stay in my own house. Everyone I tell this to looks at me like I am an alien.
