As Creative Home Engineering states, “a thief can’t burglarize a room he can’t find.” So, to make sure your hidden door stay hidden, Creative Home Engineering offers a number of non-traditional hiding machines. Sure, they’ve got the standard revolving bookcase and sliding wall panels. But, the company also constructs hidden doors from grandfather clocks, fireplaces, paintings, stairwells, and other household fixtures. They also offer an option that allows your hidden door to double as a vault door, so your valuables stay double protected.

Priced from $5-$250K, you’ll probably want to make sure you’ve really got something big to protect to make the purchase worth your while. But, even if you don’t, Creative Home Engineering claims that a quality hidden door can make a solid investment from an appreciation standpoint. And, if you’ve got nothing to hide, the bragging rights are definitely worth something as well.
