In one campaign I ran the heros had taken over for the deceased superteam that previously occupied the top ten floors of a Manhattan skyscraper. They had to remodel after the explosion that killed said supers and were well funded, so they went full-on MTV cribs.
However, after a major hunted (Finn, the killer robot) took the elevator up to the base and blasted a hero in the kitchen, they remembered to add some security devices like locks on the doors.
The killer robot in question was rebuilt and reprogramed (with a built in coffee maker.) He became the housekeeper, handyman, librarian, recepionist, and security chief. Sixty years later in continuity, he's the supreme mage on Earth.
