My first world has a wooden house on the top of a mountain. Then it burnt down. So I rebuilt it with the same design as glass and my containers didn't burn. Only now it is stone.
Next world I have a mine entrance secured with cobblestone on all sides on the side of a rockface. Then it has a 45 degree slope with tracks for my minecarts to go up and down to the mine.
