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

by Aurora Nov 30,2025

LEGO collectors, here's your final opportunity to grab an amazing deal on an officially retired LEGO set. Amazon currently offers the LEGO Ideas Treehouse 21318 for $174.99 – a 30% discount from its $250 MSRP. While originally priced at $200 during launch, LEGO increased prices across several sets including this one in 2022. This deal brings it below even its introductory price, an exceptionally rare find for discontinued LEGO sets.

Imagine the popular LEGO Bonsai kit, but supersized – that's the Treehouse set. With 3,036 pieces, this massive construction measures 14" x 10" x 9" and weighs over 8 pounds. Designed for builders 16+, this complex set reveals hidden details beyond its impressive tree structure. The landscaped base features picnic seating beside a buildable stream, while the treehouse includes three detailed cabins with removable roofs and furnished interiors. A functioning windup crane and interchangeable foliage allow seasonal customization. Notably, all botanical elements use sustainable plant-based plastics instead of traditional petroleum-based materials.

This Amazon Lightning Deal won't last long. Having already sold out at LEGO's official shop, this marks one of few remaining opportunities to acquire it. The LEGO Ideas series consistently delivers unique designs with impressive scale and complexity. Unlike typical display sets, the Treehouse offers interactive elements including accessible cabins, operational crane mechanics, and customizable greenery. Even at full price, this exceptional build earns our highest recommendation.
