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

May 13,2025 Author: Gabriella

LEGO enthusiasts, don't miss out on this fantastic opportunity to snag a highly sought-after retired set at a stellar discount. Amazon is currently offering the LEGO Ideas Treehouse 21318 for just $174.99, a whopping 30% off its original $250 list price. To put this into perspective, this set initially launched at $200, but LEGO increased its price in 2022. This deal not only brings it below the original launch price but also marks a rare chance to own a discontinued set at such a reduced cost.

30% Off LEGO Ideas Treehouse 21318 (Officially Retired)

Sale Price: $174.99 at Amazon

If you've enjoyed the LEGO Bonsai kit, the Treehouse can be seen as its grander counterpart. With a staggering 3,036 pieces, this set constructs into a 14" x 10" x 9" model that weighs over 8 pounds. Designed for builders aged 16 and up, this complex creation isn't just a tree—it's a detailed world. The base showcases a beautifully landscaped area complete with a picnic setup and a buildable stream. The treehouse itself features three distinct cabins, each with removable roofs and fully furnished interiors. A unique windup crane adds functionality by allowing you to hoist supplies to the treetop. Seasonal versatility is ensured with sets of both green and yellow leaves. In alignment with the set's environmental theme, all plant and tree elements are crafted from renewable plant-based plastic rather than petroleum-based alternatives.

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. As a fan of the LEGO Ideas series, I appreciate its diverse designs, challenging builds, and impressive scale. The Treehouse stands out for its interactivity, featuring accessible cabins, a working crane, and seasonal foliage swaps. Even at full price, this set would be a top recommendation.
