Legos are for Grandma too!
Style: Kit
I am a 60 year old woman - this is my SECOND lego set! Lol! My first was the "Friends" TV show set I got for Christmas. I got it just because I've always liked that show, and thought it might be fun to build. I had so much fun putting that together, and seeing how much it looked like the TV show set and all the detail! It was a relatively small Lego set, and I was really kind of sad when I was done! But, I really didn't expect to do any more lego sets. My hubby was amused that I enjoyed "Legos" and surprised me with this Treehouse set of over 3000 pieces! I got it this month, and I've been working on it a little every night. I just want to relish every little moment of construction - so I'm not rushing it. (Plus - I do have a full-time job!) Usually, in the evenings, you'll find me crocheting, painting or doing some other craft while I watch TV with my hubby, but now you find me playing engineer and building legos! Lego building is a first for me! (Except for the little things I've done with my kids and grands.) I'm really enjoying all the DETAIL that is in these sets! Its a surprise to not really know what you are building, until the final piece is in place - and all of a sudden you see its a bed or a coo-coo clock, a bird house or a toilet! Lol! Its an adventure every time I complete a new step. I've had to learn how to read the instructions, and determine where each one goes. I've had to take it apart a few times because I did it wrong. But, its taught me to pay closer attention to the small details. It has been so fun. I'm about 1/2 way into construction and look forward to seeing the completed piece. However, not to seeing this adventure come to an end! I secretly caught my hubby perusing Amazon for another set for me last night! I guess this proves - you can't be too old for Legos! I can imagine I'm going to have to watch my grandkids - that they won't destroy my masterpiece! Because, it will be a very tempting toy! This is a beautiful treehouse with lots of great imagination built in! Love it! ... 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

My favorite set. Probably.
Style: Kit
I can't believe I lucked out in getting one of these in the few minutes they were in stock at normal price a few months ago. I went a little bonkos with Lego during quarantine and saved this for last. It was worth the wait. The beginning was a little bland and had me worried but then the details started kicking in and the huts themselves were so fun and clever. Am I wrong in thinking this is the only Lego set with a full bathroom, including a shower? Lego City must be STINK. Anyway, I added some extra minifigures and the truck with the caravan really added a lot to the aesthetic. I know it's silly but I think my favorite feature is the creek. It's just so cleverly done. I also adore the steps and the telescope and the dining area. If I had to complain, it would be that there is no practical way for them to get to the highest hut besides walking on those branches. I may try to build my own little walkway or something but that and the little space for the minifigures to walk up in the treehouses were my only real disappointment. Otherwise, I can't stop staring at this. I love it so much. Thank you for getting me through the last seven months, Lego! ... show more

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

Retired set on Lego.com
Style: Kit
Great set! This is retired by Lego and still cheaper than MSRP price. Idk how Amazon still ships and sells, but buy now if you want it for less than retail. Cant beat $216.99

This is amazing!
Style: Kit
This is a really wonderful set. I got it on sale for $175 (I've never seen it that low again). Gift for my 20-year old son, who built it in a few days. The detail is crazy and so many things move (doors, swing, winch). The roof of each room comes off so you can see what is inside. You can change the color of the leaves as the seasons change. It's beautiful and fun. We are displaying it in our living room because I just love it! ... show more
