Since the end of November 2020, the product listing for the 3,036-piece set has advised that while you could place an order, it likely wouldn’t ship until late April. That date has now been revised to March 31, 2021, meaning you can get your hands on it a little earlier than anticipated.
The second-biggest Ideas set to date – trumped only by 21323 Grand Piano, at 3,662 pieces – was originally rumoured to retire at the end of 2020. However, it’s believed that the LEGO Group made a very last-minute decision to continue production into 2021 – hence the delay for new orders.
During that time, though, it’s never been marked as ‘temporarily out of stock’ or ‘sold out’. That means it’s been a constant fixture on Brick Fanatics’ Top 20 LEGO Sets List, which tracks the latest and greatest LEGO sets currently available to order at LEGO.com – even if they are on back order, as the majority are at the moment.
Regardless of when exactly your copy of 21318 Tree House arrives, the end result is that you’ve got another chance to pick up the 2019 set if you hadn’t already. Shoppers in the US aren’t so lucky right now: Kevin Feeser’s successful project is currently marked as ‘temporarily out of stock’, with no indication as to when it will be available to order again.
