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

Calling all LEGO enthusiasts! Here’s your golden opportunity to own a sought-after set that has just been retired from the official LEGO lineup. Amazon is currently offering the iconic LEGO Ideas Treehouse 21318 for $174.99—a fantastic 30% discount compared to its original price of $250. Interestingly, this set launched at $200 but saw a price increase across multiple LEGO sets, including this one, back in 2022. This deal brings it even below the initial launch price, making it a rare find for a discontinued set.

If you're familiar with the LEGO Bonsai kit, picture the Treehouse as its larger-than-life counterpart. This intricate 3,036-piece set spans an impressive 14" x 10" x 9" and weighs over 8 pounds. Designed for seasoned builders aged 16+, it's more than just a tree—it’s a masterpiece featuring a fully landscaped base with a picnic setup beside a buildable stream. The treehouse itself consists of three cabins, each with removable rooftops and beautifully detailed interiors. There’s even a wind-up crane to hoist goods to the treetop. Choose between lush green or vibrant yellow foliage to suit the season. Sustainability meets creativity with plant-based materials replacing traditional plastics for the flora elements.

This is a limited-time Amazon Lightning Deal, so act fast! It’s already sold out at the LEGO Shop and unlikely to restock. The LEGO Ideas series stands out due to its creative designs, challenging builds, and impressive scale. Unlike static displays, the Treehouse offers interactivity through its accessible cabins, functional crane, and seasonal foliage options. Even at full price, this set would have been a must-have for any collector.
