Back in his days of fame and fortune Booster created a mansion for himself. While he would later destroy it when attempting to flee to the future he had offices for Dirk, Trixie and himself. There were labs, bedrooms for Michelle and him, along with other goodies. I love looking at blueprints and maps so I do wish more comics had these sort of things. Not shown is the other side of the house along with the rocket powered doors. Yes, I'm serious.
