Trading 25% under its $250 retail price even after retiring — the market has had its say.
LEGO 21318 Tree House is worth about $187.21 sealed right now, based on 36 recent sealed sales. That's 25% below its $249.99 retail price. It came out in 2019 with 3,037 pieces and 4 minifigures. It was retired in Feb 2025. Over the last 83 days its typical asking price has fallen 4%, from $240.00 to $229.99. We last checked it 7 days ago.

Worth more in pieces?
Parting it out is worth about 92% more than selling it sealed — that gap is why this set gets broken.
Minifigure prices are real completed BrickLink sales. The parts figure is an estimate — the set’s own inventory at the catalogue average, not each piece priced individually. Treat it as a guide, and remember parting out is hours of work and many small sales.
eBay links are affiliate links — if you buy after clicking, we earn a small commission at no cost to you, and that is what pays for the site. BrickLink has no such programme, so those are plain links. Neither changes what we show or what we say about it.
How to read this. The value is the median of live sealed listings, after removing instructions, empty boxes, used sets, multi-set lots and implausible outliers. Real sale prices usually land below asking, so the buy-below figure is deliberately the conservative end of the range.
