Minecraft wiki entry for Hiding_chests, associated text: In the corner of your house, add a door. Be sure the handle faces AWAY from the corner, so when you open the door, the side where the door opens to is blocked. On that side, add your secret chest! You may want to make the doorway look like, for example, a furnace room, so when another player raids your house, they will open the door only to be faced with a stack of furnaces. As the door to the furnace room is opened, the chest will be hidden from view by the door itself!
