LEGO 21318 Ideas Tree House

Build a Forest Escape with the LEGO Tree House

Reconnect with nature in the most imaginative way possible with LEGO Tree House (21318), a beautifully detailed 3,036-piece set that’s as much fun to build as it is to display or play with. Designed for experienced builders and nature lovers alike, this LEGO Ideas set features three charming cabins nestled in a leafy canopy — a bedroom, bathroom, and kids’ room — all set on a lush landscape base. The set includes two interchangeable leaf designs, allowing you to swap between vibrant green summer foliage and warm autumn tones. With removable treetops and cabin roofs for easy access, plus clever touches like a swing, picnic table, bonfire, wind-up crane, and even a hidden gem for treasure hunts, this is a build packed with storytelling potential. Complete with a minifigure family and a bird, the LEGO Tree House brings the magic of outdoor adventure into your home.
