I'm still getting the hang of it too. I still have yet to figure out how to build some of these red stone contraptions people make. Four and a half years and I'm still learning how to build houses here LOL. Here it is I got my wife addicted to this game and now she is better at it then I am. I'm good at survival mode playing for adventure. She is good at creative mode building houses like your son is. She has built several houses like the one your son built. Her latest creation was modifying a desert pyramid into a fortress.
