LEGO collectors, don't miss out on this incredible opportunity to grab a highly sought-after LEGO set at a steep discount.

It's worth noting that when this set was first released, it was priced at $200, but LEGO increased the price to $250 in 2022. This deal brings it below even its initial launch price, which is a rare occurrence for a set that has been officially retired.

If you've enjoyed the LEGO Bonsai kit, you'll find the Treehouse to be a scaled-up version of that experience. With 3,036 pieces, this set creates a stunning model that measures 14" x 10" x 9" and weighs over 8 pounds. Designed for LEGO enthusiasts aged 16 and above, the Treehouse is a complex build that goes beyond just a tree. It features a beautifully landscaped base complete with a picnic area and a buildable stream. The treehouse itself consists of three distinct cabins, each with removable roofs and detailed interiors. There's also a functional windup crane for lifting supplies to the treetops. To add to the realism, the set comes with both green and yellow leaves, allowing you to switch between different seasons. Moreover, in line with its environmental theme, all plant and tree elements are made from sustainable, plant-based plastic instead of traditional petroleum-based plastic.
This is a limited-time Amazon Lightning Deal, so it won't last long. It's already sold out at the LEGO Shop and is unlikely to return. The LEGO Ideas series stands out for its diverse designs, challenging builds, and impressive scale. The LEGO Treehouse, in particular, offers more interactivity than typical display sets, with accessible cabins, a working crane, and seasonal foliage. Even at full price, this set is highly recommended for LEGO enthusiasts.
