From the outside, video game mogul <a href="http://richardgarriott.com/">Richard Garriott</a>'s New York City home looks very much like a typical Manhattan townhouse. And even once inside, the stately 16-foot-wide residence betrays little of its peculiarity, except for a few choice decorations like mummy hands and a vampire hunting kit. But just like the video games Garriott made his fortune developing, his <a href="http://inhabitat.com/nyc/video-game-moguls-unusual-home-conceals-a-trick-bookcase-secret-passageways-and-other-surprises/richard-garriot-ny-home/">Murray Hill brownstone</a> conceals all kinds of <a href="http://inhabitat.com/nyc/video-game-moguls-unusual-home-conceals-a-trick-bookcase-secret-passageways-and-other-surprises/richard-garriot-ny-home-bas/">twists and surprises</a> within.

But as with his past homes, like the famous <a href="http://www.businessinsider.com/richard-garriott-house-2011-10?op=1">Brittania Manor </a> in Austin, Texas, the adventure-loving entrepreneur decided to add a few of his own special touches.

When examining his new property, Garriott realized that there was a door that didn't seem to lead anywhere.

Upon further inspection, he discovered a "sidewalk vault" that sits directly below the city street in front of his residence.

The formerly unused tiny space was fully renovated, and now it functions as the perfect subterranean wine storage area.

There are surprises around every corner of Garriott's house.

The home features several secret passageways, but the cutest one has to be the hidden entrance into Garriott's daughter's room.

Disguised as a bookcase displaying a group of tin toy <a href="http://en.wikipedia.org/wiki/Automaton">automatons</a> (Garriott believes he has the largest collection of automatons in the world), the seeming dead end swings inward to grant access to the room behind it.
