DIY Secret Passage Adds Mystery to Your HomeS

There's really no doubt about it: secret passages are totally awesome. Which is why I can't help but be smitten by this homemade hidden door that exposes a messy, messy office.

Constructed using a pair of Ikea Billy bookcases, a piece of fiberboard and some hinges. Sure, it would be easier to just clean the office rather than hide it away. And yes, you'll be worrying about knocking stuff off of your bookshelf every time you open and close the door. And light leaks from around it when the light is on in the office. But guys, it's a secret passage! A secret passage is always worth it. [Flickr via Lifehacker]
