LEGO reveals 21318 Ideas Treehouse, featuring 3,000 pieces and foliage for 2 seasons [News]

Today LEGO is officially taking the wraps off the latest set originating from its crowd-sourcing platform, LEGO Ideas. 21318 Treehouse is the largest Ideas set yet, with a whopping 3,036 pieces. It stands more than 14 inches tall and features leaves in two colors to build either summer or fall versions. First announced last fall, the treehouse features three cabins and four minifigures. Be sure to check out our full, hands-on review of it that we published earlier today, and continue reading below to see all the official images and information.

Despite the enormous part count, the set will retail for US $199.99 CAN $269.99 | UK £179.99. It’s slated to be available in LEGO stores and the LEGO Shop Online tomorrow, July 24, though LEGO did accidentally sell the set briefly to very excited–and surprised–fans last week at San Diego Comic Con, before pulling it from shelves.

Set up as a fancy campground, this isn’t your average backyard treehouse. The massive tree contains three cabins, just like the original Ideas project by Kevin Feeser.

TreehouseWhile LEGO has adapted the design and spruced it up, it does retain the removable roofs, curving stairway, and rope bridge.

One of the most interesting aspects of the set, however, is LEGO’s decision to include two sets of leaves. While Kevin’s project used entirely green leaves, LEGO has included an entire second set of leaves in autumn colors, including flame-yellowish-orange leaves, which are a new color for that element.

The leaves themselves employ LEGO’s new plant-based plastic, as do many of the botanical elements around the base. In total, there are more than 180 such pieces in the set, the most included in any LEGO set yet. The top of the box has a key displaying precisely which elements use plant-based plastic. If you want to learn more, check our article on LEGO’s sustainable plant-based plastic.

Below the leaves, the cabins are fully decked out with details. The three rooms are the main bedroom, the bathroom, and the kids’ room.

A nuclear family of four minifigures are included, with a mother, father, son, and daughter, each dressed in rugged camping gear.

    It’s a nice looking set that I would like to buy but I cannot support this unethical green-washing by The LEGO Group!

    Traditional petroleum based LEGO is far greener than bioplastics surely!?

    Petroleum based LEGO locks up the carbon that would most likely otherwise be combusted as fuel.

    Plant based LEGO uses up valuable arable land that could be used to feed people. Hence it reduces the food supply while increasing the cost of the remaining food which in turns means it is the poorest who are worse affected by the reduced food supply.

    Another worry I have is that the new LEGO is not biodegradable so they are taking biomass out of the ecosystem and turning it in to a form where it cannot be recycled as biomass, hence degrading the resources available to the ecosphere.

    Am I missing something? How does this help the planet?

    “While LEGO has adapted the design and spruced it up”
    Spruced it up? Wow, just wow. I thought TBB was above bad puns, I guess I was wrong.
