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 sayโit 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 meโbut not necessarily for you.
That's why I'm insanely proud to introduce a solution.
Secret Bookcase Door Cut List Generator
