LEGO enthusiasts, this is your final opportunity to snag a phenomenal deal on a retired LEGO set. Amazon is currently offering the LEGO Ideas Treehouse 21318 at a remarkable 30% off, priced at $174.99, down from its original $250. It's worth noting that this set launched at $200, but LEGO increased the price to $250 in 2022. This discount not only brings it below the initial launch price but also marks a rare opportunity for a discontinued set.

If you enjoyed the LEGO Bonsai kit, the Treehouse can be seen as its grander counterpart. Comprising 3,036 pieces, this set measures an impressive 14" x 10" x 9" and weighs over 8 pounds. Designed for builders aged 16 and up, it presents a complex yet rewarding build. At first glance, it's a majestic tree, but delve deeper, and you'll discover a fully landscaped base with a picnic setup beside a buildable stream. The treehouse features three separate cabins, each with removable rooftops and detailed interiors. Additionally, a windup crane is included for hauling goods to the treetop. The set comes with both green and yellow leaves, allowing you to switch between seasons. Embracing its 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 act fast as it won't last long. It's already sold out at the LEGO Shop and unlikely to return. The LEGO Ideas series is renowned for its diverse designs, intricate builds, and impressive scale. The Treehouse set stands out with its interactivity, offering accessible cabins, a functional crane, and seasonal foliage options. Even at full price, this set is highly recommended.
