Minecraft wiki entry for Defeating_a_woodland_mansion, associated text: The woodland mansion is a nice looking structure. Turn the mansion into your base. Light it up and clear out all hostile mobs. Fix all creeper holes and fire damage. You can use the original rooms, or tear down the inner walls and build them how you want. You can take all the furniture to add your own. Make sure to change the wool beds in the bedrooms into real beds so you can sleep in them. Placing two beds next to each other makes a wide and good-looking bed. Add a kitchen, bathroom, better bedrooms, anything you want. You can even redesign the whole mansion, but it will take a long time to do so. Be careful if you want to redesign the sides of the roof to make it look nicer, as you can fall from up to twenty blocks and possibly die. Putting farms on top of the mansion's roof can be effective for food since sunlight helps crops grow faster. Don't worry about Illagers as long as you've explored all the rooms and killed all of them since they never respawn, unlike pillagers.
