The instructions are good, but it got tricky when creating the 2nd level of the house. My 11yo daughter rec'd this set for Xmas. We got this set because she loves constructing houses out of different materials and we thought she might enjoy trying this out - which turned out to be true. She felt quite satisfied once she had completed the finished project.There are very few lego sets that appeal to older girls so I would really recommend this one! My childhood love for Legos, building things with my hands, and drawing out house floor plans all came together with this series.
