The second-largest LEGO Ideas set – trumped only by 21323 Grand Piano – has bounced between “available now” and “temporarily out of stock” since it arrived in 2019. And it’s now once more shifted to the latter status, at least on the UK version of LEGO.com.
Given the £179.99 set is rumoured to be approaching retirement, there’s a chance that it may not come back in stock at all. But if it does, you shouldn’t hang around: after all, it may be your last chance to pick it up.
In our review of 21318 Tree House, we concluded that it’s “packed with whimsical charm, looks excellent on display and is an awful lot of fun to build.” For those reasons, we’ve also picked it out as one of the best LEGO sets retiring in 2020 to buy for building.
