LEGO Ideas Tree House 21318 – 3036-Piece Tree House with 3 Cabins and Interchangeable Leaves

Overview

The LEGO Ideas Tree House 21318 is a richly detailed, 3036‑piece building set designed for adult builders and families who love immersive constructions. Part model, part display piece, it invites you to explore a towering tree home with three distinctive cabins, a playful landscape base, and a host of imaginative accessories. The tree top and cabin roofs come off for easy access, so you can inspect each nook, rearrange scenes, or simply admire the craftsmanship from every angle. The set blends tactile building with creative storytelling, making it a standout addition to any LEGO collection.

With more than 180 plant-based, polyethylene leaves and seasonally changing foliage, this kit offers a tactile, vibrant build that ripples with color through summer, autumn, and beyond. The leaf elements can switch between lush green for the warmer months and a warm yellow/brown palette for fall, giving you a dynamic centerpiece for display or play across the year. At over 14 inches tall and with a broad footprint, the Tree House presents a impressive presence on a shelf or a dedicated display table.
