  • Nice one! Definitely worth it.
Style: Kit
Absolutely love this one!! The build was super fun and detailed, and it looks amazing on display with two different leaves. Great quality as alway. It has over 3000 pieces so took me and my gf 30 hours to complete. Totally worth the time and money! The only thing you may consider before purchasing is this is a bit large, so you might need some spot for it at home ... show more

  • Creative and fun product that brings people together!
Style: Kit
This was worth every penny! I gifted it to my husband. The step by step instructions were easy to follow. Our family worked on it together, ages 7-42. We have used it as a center piece for our dinner table and now have it as a decorative piece on our shelf. It has been a frequent conversation starter with visitors of all ages and even a piece that provides family dinner bonding experiences allowing us to play games like I Spy. ... show more

  • Fun Lego set to build
Style: Kit
This Lego set was fun to build I was a little intimidated by the 16 and up rating but there was no need. The build was not to simple but not difficult enough to be frustrating. I have built Lego sets that are frustrating because have confusing instructions based on the angles in the workbook and I often need to take a break when this happens to get a new perspective. But this Lego set was just difficult to be entertaining. The detail on this Lego set was very precise. I enjoyed all the plant life and the detail in the rooms based on the interest. I also enjoyed the little hidden details like there is a hidden gem and a map that goes with it. It came in a large box which I was surprised at and it came out taller than I expected. But this was a pleasant surprise. I really enjoy it. The way this Lego set looks it has a playfulness to it as well as lots of details like the swing and the picnic table as well as the bird's nest. I do wish it had more animal life because it would be nice to have a squirrel or a frog by the river. This was overall my favorite Lego set I've ever created and it's sitting on my desk so I can always look at it. ... show more

  • Tree house for life
Style: Kit
This Lego tree house brick build is an absolute joy to put together. The branches and leaves brings a smile, bringing the entire set to life. As you build, it truly feels like you're being transported back to your childhood, reliving the excitement of playing in a tree house and dreaming of one day building an even better one. One of the standout features is the ability to change the leaves to reflect the different seasons, making it a set that can be displayed and enjoyed all year long. The inclusion of mini-figures adds an extra layer of fun, allowing for imaginative play alongside the beautiful display. This set is sure to become a cherished and long-lasting addition to any Lego collection, filled with nostalgia and creative possibilities. ... show more

Great value, as I found this on sale! The treehouse is fun to build; yet takes some time as it is pretty large. Very entertaining!
