This thing is amazing! If you are decently handy and have a useless friend who can lift 35 pounds, and 2 cordless drills the basics will go together in 4-6 hours: the base, the swing-arm, the swings, slide and ladder and walls/window insets. That was a Sunday afternoon from lunch to dinner. 

Then you can add the accessories as time allows over the course of the next few days/weekends: add the kitchen in a free hour, Add the roof in another free hour, Etc.

Super study and ideal for kids less than 8. (There are 8-10 years who have been on it but it’s a little undersized for them). Even once the first part was assembled, we were able to lift it up and adjust the angle of the slide to our desire. Awesome set!
