So you're playing Top Secret or Marvel Super Heroes or Mystery Men! or Villans and Vigilantes or ICONS and you need a bad-ass bachelor pad for your suave master spy, playboy secret identity, or lecherous evil villian. I got you covered:

And the text describes the pad enough that it's almost playable right off the page. Add some treasures, hidden weapons, a secret passage or two and you are good to go.
Here's a site that provides a virtual fly-through of the house!
