The Showtime House
Have you seen the Showtime House? Sponsored by Metropolitan Home, each room was designed with a different Showtime TV show in mind.
The most steampunk is The Tudors Living Room. The era isn't Victorian, but it has a lot of design elements in common with steampunk -- antiques, brass surrounding the fireplace, and industrial inspired lighting.
The Dexter Dining Room is not at all steampunk, but is incredibly creative and over the top, in a very macabre way.
Also, don't miss the book tower in the Californication Study.
