Broken shows you how to make your own hidden door book shelf –

Wall to wall bookshelves that conceal a hidden door. Made without casters.

My home office was messy. After I am done it will still be messy but now it is finished AND it has the secret feature. Well it was secret, till I wrote this.

In one wall of my home office is a 5 feet tall 2 feet wide door to access the storage area and crawl space under the garage. This is where we put holiday decorations, old stuff, and junk.
This wall was the perfect spot for floor to ceiling bookshelves , which I have done lots of , but it had this door in the middle of the wall. The perfect answer was a bookshelf that opened.

One day my father in law visited and we started drawing pictures of how book shelf hidden door could work , how to hinge, where to hinge, how to hide opening, etc.
