Wall to wall bookshelves that conceal a hidden door. Made without casters. Some people call this a bookcase. 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. Following are the highlights from the journey that followed.
First thing I did was figure out how big and where a bookshelf would need to pivot in order to clear walls and neighboring shelves with minimum gaps. I positioned the hinge point 7&quot in from the right and 2&quot in from the front of the cabinet. For sanity I made a scale drawing of shelves and cut out the rotating shelf shape. With a pin I tried different pivot ideas, validating my measurements. The goal was to have the vertical gap between moving shelf box and fixed shelves be covered with a single 4.5&quot trim piece. I added a better drawing of the key part of the unit, the moving center. The left and right side shelves are not to scale. This was made with visio, which lets you adjust the rotation point, so i could simulate the shelves opening to show clearance.The visio file is attached if can read it. the close up is where i notched the vertical trim to allow the horizontal trim to pivot &quotthrough&quot it. -Ken So let us take a look at 21 nice pictures door latch hidden below.

The next key insight, thanks Jim, was to build a steel frame rather than trying to hinge the wood shelves directly. This would allow the door to swing easily and support 500-1000lbs without a problem ( full bookshelf). I calculated the size for the frame allowing minimum clearance from the floor for trim and base board (2&quot ) and enough clearance from the ceiling for the metal frame barely below crown. ( 5&quot) and the width was set to just cover the access door and be centered ( 42&quot). The steel 2x2 box was $90 cut to length with miters. I bought a couple of 3/4&quot bolts to act as the pivot pins. These were welded 7&quot in at center of bolt, from ends of the frame , and cut off to fit into 2x2 box anchors. My welding is not super, so I do a lot of welds.The steel frame would pivot on a upper and lower anchor point, mounted to ceiling and floor respectively.
