I brought this up when I was looking to buy the house I now live in, last June. (Hidden doors and unseen spaces).
As several people here have noted, there was no way to even bring up the subject to contractors without all kinds of suspicion arising, as they wondered if I was a drug dealer or what I had to hide that was so valuable. Alternately, they would start telling me about others they've done, and you could see they just couldn't wait to add this one to their resume. In the end I found that a space big enough to walk into would be more difficult to conceal, and I just didn't have the room to spare, its not a big house.
So like anything else, you just need to figure out what your priority is.
Personally, I just want to hide things not necessarily hide myself. So in several locations as construction was being done, I requested that I'd like an "access door" put in to different areas adjacent to the eves of the house (upstairs, if that's not obvious). The contractor working on my house commended me for thinking ahead, since it would create easy access to wiring and plumbing. I suppose the rest of the story I'll keep a "secret".
