Hidden Doors, Mysterious Things, Magic in our House

One thing that Mike and I can agree on is that we both love the idea of a few secret, curious, mysterious features in the house. Things like hidden doors, secret staircases, special hiding places, a dumbwaiter, that kind of thing. Clever, fun features that aren't found in more standard homes. I was searching on the internet today to find a photo for this post, and found a company that actually manufactures all kinds of hidden doors! http://www.hiddendoorsdirect.com/hidden-door-photos.html
Isn't that cool?? Mostly, when I imagine these features, I envision creating a sense of magic in the house for our kids. I want them to remember the home they were raised in as being a special place.
