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

Author : George May 22,2025

Attention all LEGO enthusiasts! This is your final opportunity to grab an incredible deal on a highly sought-after LEGO set that has officially been retired. Amazon is currently offering the LEGO Ideas Treehouse 21318 at a remarkable 30% discount, bringing the price down to $174.99 from its original $250 list price. It's worth noting that when this set was first released, it was priced at $200, but LEGO increased the prices of several sets, including this one, in 2022. This special offer not only brings the price below the initial launch cost but also marks a rare opportunity for a discontinued set.

If you enjoyed the LEGO Bonsai kit, the Treehouse can be thought of as its larger, more intricate counterpart. This set, comprising 3,036 pieces, stands at an impressive 14" x 10" x 9" and weighs over 8 pounds. Designed for builders aged 16 and above, this set goes beyond just a majestic tree. The fully landscaped base features a complete picnic setup alongside a buildable stream. The treehouse itself includes three separate cabins, each with removable rooftops and fully decorated interiors. Additionally, it comes with a windup crane for transporting goods to the treetop. The set includes both green and yellow leaves, allowing you to change the season at will. In line with the set's environmental theme, all plant and tree elements are made from renewable plant-based plastic, steering away from traditional petroleum-based materials.

This is a limited-time Amazon Lightning Deal, so it won't last long. It's already sold out at the LEGO Shop and unlikely to return. The LEGO Ideas series is cherished for its diverse designs, complex builds, and impressive scale. The Treehouse stands out as more interactive than other display-type LEGO sets, with accessible cabins, a functional crane, and seasonal foliage options. Even at its full retail price, this set would have been a top recommendation.
