Last year, the Lego Group started making flowers, trees, and shrubs out of plant-based polyethylene using sustainably sourced sugarcane. I can’t imagine a better use for all of those plant plastic p arts than this beautiful, 14-inch-tall Lego Ideas Treehouse set.


Lego Ideas is a program that allows fan designers to submit their own unique Lego builds for consideration as retail sets. Kevin Feeser from Nancy, France, submitt ed his idea for a Lego treehous e to the Lego Ideas website, more than 10,000 community members voted for it, and Lego officials picked it as the next Lego Ideas set to hit store shelves. It’s got a fancy box and everything.


One of the biggest Lego Ideas sets yet, the Treehouse set features more than 3,000 Lego elements and retails for $200. It’s 14 inches tall, 10 inches wid e, and 9 inches deep. The build consists of a base, the trunk, and some rickety stairs leading up to three cabins packed with little Lego details. It also comes with two sets of leaves for the top—green for summer, yellow and brown for fall.

The plant-based polyethylene leaves are the first steps in Lego’s plan to switch completely to sustainable materials by 2030. Fans should notice no difference between the look and feel of older plant elements and the new sustainable ones. They’re just better.

I’m running out of room for constructed Lego sets in my home, but this is the sort of epic build that might see a few of my older favorites broken down to make room.


I can almost smell the fresh plastic air.
