March 2025 Update:

Guys (and gals), this page was the first page I ever made. A few years ago, I set out to learn how to build a website, and let's just sayโ€”it was a process. That first clunky mess was barely functional, and honestly, this page's structure is still pretty bad.

But you know what? It ranks at the top of Google because it has helped so many of you build the hidden door of your dreams. I've had the privilege of talking to dozens of you, guiding you through the process, and one of the top requests I kept hearing? A cut list.

The problem? Everyone's doorway dimensions are different. My cut list works for meโ€”but not necessarily for you.

That's why I'm insanely proud to introduce a solution.

Frequently Asked Questions About Hidden Bookcase Doors

Common Questions About Hidden Bookcase Doors

Yes, with proper insulation and construction techniques, they can be soundproofed to some degree. Consider using weather stripping around edges and sound-dampening materials in the construction.
Styles can range from modern minimalistic, traditional, to rustic. Your choice depends on the overall dรฉcor of your home. We chose a rustic back to go with the theme of the room behind it.
Strong and durable woods like oak, maple, or cherry are often used, though the choice may also depend on your color and grain preferences. Try not to "cheap out" as your bookcase door is a functional piece of furniture. Not only does it need the durability of a bookcase but it also needs to be strong enough to handle constant motion.
Yes, with additional hardware and expertise, a bookcase door can be automated. You can certainly replace the bolt latch with a fingerprint reader or keypad that unlocks the door.
The weight limit depends on the strength of the supporting wall and hinges. It's important to keep the weight manageable to prevent strain on these components. The Tambee pivot hinge that we recommend has a weight limit of 110 pounds.
This depends on your lease agreement and whether the landlord allows for such modifications. Since this is a substantial renovation, most rental agreements would require explicit permission from your landlord.
Yes, with the use of fire-resistant materials and finishes, a bookcase door can be made to be more resistant to fire. Consider using fire-rated plywood and applying fire-resistant coatings when building.
Installation time can vary widely based on the complexity of the project and your level of expertise. It could take anywhere from a day to a few weeks. For beginners, expect the project to take 1-2 weekends of dedicated work.
Yes, but it's crucial to ensure the wall can support the weight and movement of the door. Non-load bearing walls can often be modified more easily, but you'll still need to ensure the frame is properly reinforced.
Yes, it's possible to modify a pre-existing door frame to accommodate a bookcase door. This is exactly what we did in this build guide, converting a standard doorway into a hidden bookcase door.
Some ideas include a disguised button, a hidden lever, a pull book (as we used in this guide), or even an electronic keypad. The key is to make the mechanism blend seamlessly with the overall design.
Yes, many people choose to integrate their secret doors with their existing home security systems. This can include adding sensors to detect when the door is opened or incorporating electronic locks that tie into your smart home system.
The best way to hide the seams of a secret bookcase door is to line the molding up as instructed in our DIY plans. Properly installed molding, careful alignment, and strategic placement of books or decorative items can help conceal the door edges.
Hidden doorway options include hidden wall panels, mirrors, paintings, or even a faux stone wall. These alternatives can be easier to install in certain spaces where a full bookcase might not be practical.
