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 steep discount of 30%, bringing the price down to $174.99 from its original list price of $250. It's worth noting that when this set was first released, it was priced at $200, but LEGO increased prices on various sets, including this one, in 2022. This incredible deal brings the price even lower than its initial launch cost, a rarity for a set that's no longer in production.

If you're a fan of the popular LEGO Bonsai kit, consider the Treehouse as its grander counterpart. With 3,036 pieces, this set creates an impressive model measuring 14" x 10" x 9" and weighing over 8 pounds. Designed for builders aged 16 and above, this complex build is more than just a majestic tree. The intricately landscaped base includes a complete picnic setup adjacent to a buildable stream. The treehouse itself features three separate cabins, each with removable rooftops and fully decorated interiors. There's also a windup crane for transporting goods to the treetop. The set comes with both green and yellow leaves, allowing you to switch between seasons. In alignment with 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 be available for long. It's already sold out at the LEGO Shop and is unlikely to return there. The LEGO Ideas lineup is renowned for its design variety, build complexity, and scale. The LEGO Treehouse stands out for its interactivity, with accessible cabins, a functional crane, and swappable foliage. Even at full price, this is a LEGO set I would highly recommend.
