This play set is endless fun for my 6yr old daughter. She been having a ball with this play set since we got it. She loves that little shaded area, at the top of the slide, where she can hangout and draw on the chalk board wall. We are so happy that she has something to do in the backyard now. To build the play set, the wife and I put in a couple hours per day for 2 days straight (during the weekend). I say it took us in total about 8hr. This includes unpacking and identifying all the parts before we started. This play set can definitely be assembled by 1 person, but it just easier and quicker with 2 people. The coolest thing about the play set is there an app called BILT, that can be downloaded to the phone to assist with the assembly. The app itself is interactive with voice guidance and colorful 3D instruction. I am blow away by how detailed the instructional app is
