Tree House

The LEGO® Tree House (set 21318) is a 3,037-piece Ideas set released in 2019, featuring a landscape base supporting a tree with three cabins — main bedroom, bathroom, and kids' room. The tree carries interchangeable summer-green and autumn-yellow leaf elements (both molded from sustainable plant-based polyethylene), and the treetop and cabin roofs lift off for interior access. Play features include a buildable picnic table and seats, swing, bonfire, treasure map with a hidden gem element, and a wind-up crane on the bedroom balcony. Includes mom, dad, and two children minifigures plus a bird figure. The first LEGO set to incorporate sustainably sourced plant-based bricks.
