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

Author : Emery May 29,2025

LEGO enthusiasts, here’s your final opportunity to grab a fantastic deal on a sought-after set that’s already been officially retired. Amazon is currently offering the LEGO Ideas Treehouse 21318 for $174.99, marking a 30% discount from its original price of $250. It’s worth noting that when this set launched, it was priced at $200, but LEGO increased prices across several sets, including this one, back in 2022. This current price brings it even lower than its initial launch cost—a rare occurrence for a discontinued set.

If you’re familiar with the popular LEGO Bonsai kit, think of the Treehouse as its grand cousin. This 3,036-piece set stands tall at 14” x 10” x 9” and weighs over 8 pounds. It’s a challenging yet rewarding build designed for an older audience (16+). At first glance, it appears to be a stunning tree, but there’s much more beneath the surface. The meticulously landscaped base features a complete picnic setup beside a buildable stream. The treehouse itself consists of three separate cabins, each with removable rooftops and beautifully detailed interiors. There’s even a wind-up crane for hauling goods to the treetop. Both green and yellow leaves are included to create either a lush summer or autumn vibe. Plus, the eco-conscious design uses plant-based plastic instead of petroleum-based materials, aligning perfectly with its natural theme.

This is a limited-time Amazon Lightning Deal, so it won’t last long. It’s already sold out at the LEGO Shop and unlikely to restock. The LEGO Ideas lineup is a personal favorite due to its creative designs, intricate builds, and impressive scale. The Treehouse offers interactivity beyond typical display models, featuring accessible cabins, a functional crane, and seasonal foliage options. Even at full price, this set would have been highly recommended.
