Build a detailed tree house with LEGO Ideas. Features lush green leaves and brown tree trunk. Includes mini-figures and accessories. LEGO Tree House! We got about 1/3 way done then never got around to finishing it. You can see in the photos that the pieces we used are packaged in ziplocs and the rest are in their brand new packaging. I took extra care to be sure all pieces are included. The instruction booklet is in great condition and included. This is an expensive set brand new - currently $250 on Amazon.
