This review is for the Creative Kit. My 10 year old son is obsessed with Mark Rober and all of his Crunch Lab videos, so he was thrilled to check out just what this kit might contain!
This box was sent to us at no cost for review. (Check out our editorial guidelines to learn more about how we review boxes.)
Creative Kit - Architect's Treehouse
Starting with the box — this simple cardboard package looks pretty ordinary at first, but my son immediately spotted Mark Rober’s name and the CrunchLabs logo and was thrilled! The intriguing illustration on the front hinted at what was inside, and Charlie couldn’t wait to discover what creative adventure awaited him!
The box was packed well, everything fit securely without being squished. Within the box items were grouped in bags, however they were not labeled.
The instructions were second to none. With clear tips, great illustrations, and plenty of creative opportunities, this project was both fun and stress-free. Similar to LEGO instructions, my 10-year-old was able to follow the pamphlet completely on his own without any help. Not only did the booklet include step-by-step directions, but it also featured information about architects, fun applications, and even tips for making a mini-movie!

Charlie loves Mark Rober and has watched nearly every CrunchLabs video ever released. He was absolutely thrilled to receive this creative kit and was so excited that we ended up opening it way too late at night—just to check it out (and then of course build)!
Parts and Pieces
As I mentioned above, the parts and pieces in this kit were neatly packaged in separate bags. Although they weren’t labeled, it was easy to tell them apart. Everything needed was included, and the pieces were high quality and fit together beautifully. From my first glance, I was impressed—and Charlie was thrilled to see how many pieces there were. This kit is seriously jam-packed!
Build
This kit was packed full of fun wooden pieces, felt stickers, accessories, and opportunities for creativity. Charlie was able to build the treehouse all by himself and loved that he could customize it however he wanted. He especially enjoyed the cute illustrations and all the extras included in the booklet. Everything fit together perfectly, and it was truly a stress-free experience for Charlie—which is always a win!
How cute is this little treehouse!? Charlie loved putting it together and had so much fun adding his own personal touch to every part of it.
Along with the treehouse kit, we received a little wooden board to keep track of which boxes we’ve completed and a QR code linking to a Mark Rober video. The video provides step-by-step instructions on how to build the treehouse and shares details about a mini-movie competition! Charlie was so inspired that he created his own movie to try to win a platinum ticket to visit CrunchLabs and meet Mark Rober. What fun!
Final Thoughts - Was This Box Worth It?
Absolutely! This box wasn’t just created by one of Charlie’s favorite YouTubers — it was also a blast to build and play with. The kit was thoughtfully designed, made with high-quality materials, and has held up through many days of Charlie’s daily play. His favorite part was being able to add his own flair and customize it to his liking. While it was quick to build, it has provided countless opportunities for creative play. We definitely can’t wait to see what next month’s build will be!
