21318 Treehouse is a 3,036 piece Ideas set released in 2019. This set, which was originally submitted by Kevin Feeser (a.k.a. KevinTreeHouse in October 2017), and was reworked to be an official LEGO set by LEGO Designer César Soares. While Feeser ’s project used entirely green leaves, LEGO has included an entire second set of leaves in autumn colors, including flame-yellowish-orange leaves

While the MSRP is $249.99, the current average price on the secondary markets is around $233. The set is estimated to retire sometime within early to mid 2024. Once retired, the expected annual growth will be close to 6% after the second year, which will value the set between $295 and $313 shortly after it is retired.
