Since LEGO has officially discontinued production, this might be your last chance to grab this collector's item at such an incredible value.
LEGO Ideas Treehouse 21318 (Retired) - 30% Discount
LEGO Ideas Tree House 21318
$249.99 $174.99 at Amazon (Save 30%)
The LEGO Ideas Treehouse is like an expanded version of the popular Bonsai set on a grander scale. With 3,036 pieces, this massive 14" x 10" x 9" build (weighing over 8 pounds) offers an engaging challenge for builders 16+. Beyond its impressive tree structure, discover three detailed cabins with removable roofs and fully furnished interiors. The scenic base includes a picnic area and constructed stream, complete with a functional wind-up crane. Choose between green or yellow foliage to represent different seasons. Environmentally conscious builders will appreciate that all botanical elements use sustainable plant-based plastic rather than traditional petroleum-based materials.
