LEGO enthusiasts, this is your final opportunity to grab an exceptional retired LEGO set at a remarkable price. Amazon currently has the LEGO Ideas Treehouse 21318 on sale for $174.99—a 30% discount off its $250 retail price. Originally launched at $200, LEGO increased prices across multiple sets in 2022, making this deal even rarer as it now dips below the original launch price.
LEGO Ideas Treehouse 21318 – 30% Off (Retired Set)

WAS $249.99 NOW $174.99 (SAVE 30%) AT AMAZON
If you loved the LEGO Bonsai set, the Treehouse takes it to another level. This 3,036-piece set stands at an impressive 14" x 10" x 9" and weighs over 8 pounds, designed for builders aged 16+. Beyond its towering tree structure, discover intricate details like a landscaped base with a picnic area, a winding stream, and three fully furnished cabins with removable roofs. A functional crane adds playful utility, while interchangeable green and yellow leaves let you switch between seasons. True to its eco-conscious theme, all botanical elements are crafted from plant-based plastic rather than petroleum-derived materials.
This Amazon Lightning Deal won’t last long—the set is already sold out at LEGO’s official store. As a fan of the LEGO Ideas series, I appreciate its creative designs and challenging builds. The Treehouse stands out with interactive features like accessible cabins, a working crane, and seasonal customization. Even at full price, this set would earn my recommendation.
