Article: Village houses can be made out of any material you want.  Not all materials require tools to harvest or mine, but tools make the process quicker.  Read "How to Make Tools in Minecraft" to learn more about how to craft tools.  The following are common materials, and how to gather them:   Dirt:  Dirt is found all over.  To gather dirt, simply attack with your hand (or a shovel) until the dirt block breaks apart and drops a small dirt block.  Walk over the small dirt block to collect it.   Wood planks:  To gather wood walk up to a tree and attack the trunk with your hands (or an axe) until the trunk blocks break apart and drop a small wood block.  Walk over the wood block to pick it up.  Then open the crafting menu and craft wood plank blocks from the wood.  Cobblestone:  Cobblestone is a bit sturdier (and more resistant to creeper explosions).  To mine cobblestone, you first need to craft a pickaxe and equip it.  Use the pickaxe to attack stone blocks inside caves or along the sides of mountains. Make sure the location you select is within the village.  The game calculates the center of the village as the average coordinates of all the doors in the village.  The outer parameter of the villages is either 32 blocks from the center or the furthest door, depending on which is greater. Use the materials you gather to build the outside of your house or structure.  It can be any shape you want as long as it has opaque blocks overhead to act as a roof.  It should be at least three blocks tall so that the villagers (and the player) have room to move around inside.  Leave a space that is 2 blocks high in the wall for the door. To build, place your building material in your hot bar at the bottom of your inventory.  Highlight the material in your hot bar to equip it.  Place the reticle in the center of the screen where you want to place a block of the material, then right-click (or press the left trigger button) to place a block.  Read "How to Build in Minecraft" to learn more about how to build. A crafting table is built using four wood plank blocks in the crafting menu.  After you build a crafting table, place it anywhere in the world. To craft a door, select the crafting table and place 6 wood plank blocks in the 3x3 grid in the crafting table.  Drag the door into your inventory. To place the door in your structure, place the reticle in the center of the screen at the base of the space you left for your door.  Then right-click (or press the left trigger button on your game controller) to place the door.  The more doors in a village, the more the villagers are likely to be willing to breed. Villagers can detect a door that is 16 blocks in either horizontal direction, and 3 blocks above, or 5 blocks below the ground level of the village.  A valid door must have more opaque overhead blocks within five blocks of one side of the door (inside) than on the other (outside).
