Last Chance: Save 30% on Discontinued LEGO Ideas Tree House 21318

Author : Michael May 13,2025

Attention all LEGO enthusiasts: This is your final opportunity to snag a fantastic deal on a highly sought-after retired LEGO set. Amazon is currently offering the LEGO Ideas Treehouse 21318 at a special price of $174.99, marking a 30% discount off its original $250 price tag. It's worth noting that this set was initially priced at $200 upon its release, but LEGO increased the prices of several sets, including this one, in 2022. This incredible deal brings the price below the launch price, which is exceptionally rare for a discontinued set.

If you're a fan of the popular LEGO Bonsai kit, imagine the Treehouse as its larger counterpart. This impressive 3,036-piece set measures 14" x 10" x 9" and weighs over 8 pounds, making it a complex build designed for an older audience (16+). At first glance, it may appear as just a majestic tree, but there's much more to discover. The fully landscaped base includes a complete picnic setup next to a buildable stream. The treehouse itself features three separate cabins, each with removable rooftops and fully decorated interiors. Additionally, there's a windup crane for hauling goods up to the treetop. You can choose between green and yellow leaves to reflect different seasons. In line with the set's eco-friendly theme, all plant and tree elements are crafted from renewable plant-based plastic rather than 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 is a personal favorite due to its diverse designs, complex builds, and impressive scale. The LEGO Treehouse stands out as more interactive than typical display LEGO sets, with accessible cabins, a functional crane, and interchangeable foliage. Even at full price, this set is highly recommended.
