“Overall the LEGO Ideas Tree House (21318) is a pretty decent set for the price point. It is a great display piece and there are a lot little details inside the cabins as well as on the tree itself and on the ground level.”

The Rambling Brick
“I cannot really fault any aspect. It is comparably priced with other sets of this size – helped by the lack of licensing I am sure. I recommend this set. Its beautiful to look at, and uses interesting techniques, and is a great source of brown, nougat and dark orange bricks... More and plates, as well as foliage elements.”

About Ideas

The LEGO Ideas theme, which started in 2008 as an offshoot of the Japanese website Cuusoo, then formally known as LEGO Cuusoo, is based around a website which allows users to submit ideas for LEGO products to be turned into potential sets available commercially. If fellow users in the LEGO Ideas community up vote the project to 10000 then LEGO Group has a committee which votes on whether to build the set and release it. If the project is approved and cleared for production, it is developed and later released as an official set under the "LEGO Ideas" banner and the original designer receives 1% of the royalties and a number of free sets. Typically, a few projects are approved a year and most are rejected due to various restrictions.
