Check the Internet Archive (archive.org), sometimes old HGTV shows are available there. Also, try r/DIY, they have a lot of helpful folks who might know where to find the exact segment you're looking for.

I remember that episode! You're probably thinking of The Furniture Guys, they did all sorts of quirky DIY projects. Look up their stuff, they sometimes repost old episodes or clips on YouTube.

Wait, you're telling me you want to recreate something without even knowing the show it was on? Good luck, Sherlock. Maybe check in with some psychics, they should help.

Okay, so if it was HGTV and early 2000s, you might be looking for something like Mission: Organization or Design on a Dime. Both had DIY segments. Try searching those show names combined with 'secret door bookshelf' on Google or hit up some DIY forums.

Just YouTube it, man. There are tons of DIY secret door bookshelf videos. Doesn't matter if it's the exact one from the early 2000s, just get some ideas and start building.

You're looking for Restoration Realities; they had a segment featuring a hidden door bookshelf around 2004. Unfortunately, those episodes are hard to come by, but I'd start by looking on eBay for DVD collections since some folks sell recorded episodes from back then.

Oooh, yeah! I think I saw that too but can't remember the show name. HGTV had some cool stuff back then. Have you tried contacting HGTV? Maybe they'll have some old episode archives.

I totally remember that! I think it was an episode of Room by Room or Weekend Warriors around 2003. Have you tried checking old VHS tapes or looking on Archive.org? Sometimes they have old TV shows that aren't available elsewhere.
