Secret passage to office, pantry, or safe room - looks like a normal bookshelf
Everyone dreams of a secret passage. And while custom hidden doors cost thousands, you can build one for under $50 using an IKEA bookshelf and pivot hinges. The secret is the bookshelf stays loaded with books - it swings WITH the books on it.

| Wood screws | $2 | Lowe's |
IKEA Billy is popular because it's cheap and sturdy, but any bookshelf works. Key: it should match your decor and be deep enough to hold books (won't work with shallow shelves).
Most bookshelves have thin particle board backs. Add a sheet of 1/4" plywood screwed to the back every 6 inches. This prevents racking and keeps it square when swinging.
Pivot hinges are different from regular door hinges - they mount top and bottom, not on the side. Install top pivot 3-4" from edge, bottom pivot directly below. These bear all the weight.
Bottom pivot screws into floor (hardwood/concrete). Top pivot mounts to door header or ceiling joist. CRITICAL: both must be rock solid. Use long screws into studs/joists, not just drywall.
Load half the books on the shelf. Test swing. Pivot hinges have adjustment screws - adjust until door swings smoothly and doesn't sag. Add more books, adjust again. Repeat until fully loaded.
Install magnetic catch at the "closed" position so door stays shut. Don't use a standard door latch - too obvious. Strong magnet keeps it closed but easy to push open.
Install trim molding around the bookshelf to blend it into the wall. Paint everything the same color. Goal is to make it look like built-in furniture, not a door.
