Arizona-based Creative Home Engineering is one of the more prominent builders of hidden passageways, doors, bookcases, and the like. Prices for basic installations start at around $6,500 and, yes, they will travel to your location if needed. Steve Humble got started in the business when he could find no builder to construct a hidden room in his house.
According to a Popular Mechanics article, most clients go for the simple self-installed, door-wide bookcase hiding a room. But…
Others opt for more elaborate packages, ranging from escape slides tucked beneath the seats of chairs to a series of hidden doors, that Humble installs in person. Door-opening mechanisms can be almost anything—a chess set, a Lysol can or a flip-up Shakespeare bust equipped with a fingerprint reader. Homeowners typically spend about $10,000 on the secret-room setup, but Creative Home Engineering offers rotating fireplaces that cost about $35,000.
