This is a project that I had started, so here it is! And I did not put furniture in it, since I thought that the redstone should be the main, highlighted part. But feel free to use and customize my map, as long as you give me credit! As of that, I give CNB Minecraft credit for the double piston extender. I highly recommend CNB Minecraft for anything and everything related to redstone!
