It was simple to put up because we also use the app that they told us to use on the front of the box. The app gave us a 3D look of the doll house so we could make sure which way the parts went. It's a very huge doll house and my 4year old daughter loves it! P.S. One con I had was the garage door didn't close good enough so we had to saw some wood off to make it even but now it closes great
