"Bought this as a father daughter build. I am to old for Harry Potter but all three of my kids love it so that was my in. The second in was the sheer size of it! So my youngest and I got to build something she really liked and I was able to help her build the second largest set made. Build time was a good three days off and on. Extreme detail throughout and she plays with the completed castle as well. Lots of very unique details especially the way the stained glass was designed. It was an awesome time getting to build with her and having fun. Thanks LEGO!!"
