fantastic building project
I still need to build it, but I'm sure it will be successful and enjoyable, and I will also have a lot of fun with my grandchildren.

All about this set
Build, display, and play with this intricately detailed, 3,036-piece LEGO® Ideas 21318 Tree House playset. This complex build is perfect for experienced LEGO builders and will be loved by the whole family. It features a landscape base and 3 LEGO tree house cabins – a main bedroom, bathroom, and kids’ room. The tree has interchangeable sets of green summer leaf elements and yellow and brown fall leaf elements – these, along with various plant elements on the base, are all made from sustainable, plant-based polyethylene plastic, and the treetop and cabin roofs are removable for easy access. The model is packed with play-inspiring features, including a buildable picnic table and seats, swing, bonfire, treasure map, and a hidden gem element to play out a treasure hunt, and a wind-up crane on the balcony of the bedroom cabin. This unique creative toy makes a great birthday gift and comes with mom, dad, and kids minifigures, plus a bird figure, to role-play fun family scenes. It also includes a booklet with building instructions and information about this LEGO Ideas set's fan creator and LEGO designer.
I've been wanting this tree house for awhile, unfortunately got it when prices have risen. This is a great build but the in the instructions are quite hard espy for the tree trunk,I found that most instructions are highlighted or blanked out but this just had arrows which was quite hard when working on brown on brown,also once the tree top and leaves are on its hard to access the huts to take the rooves off.also what is with the scissors under the parents bed??I love all the quirky little bits,it's fun to make all the huts,hardest bit is the trunk. Got it in my newly decorated bedroom.i bought the egg and fried egg from another store. I've been wanting this tree house for awhile, unfortunately got it when prices have risen.
