How to build the Underground Bunker

  1. 1

    Dig

    Dig a 15 by 15 pit 7 blocks deep.

  2. 2

    Shell

    Line the pit with stone bricks: floor, walls and a ceiling 5 blocks above the floor. Replace the inner floor with polished andesite.

  3. 3

    Rooms

    Build an inner wall from front to back through the middle, then a wall across the east half to make two rooms. Open a 1 by 2 doorway in each.

  4. 4

    Entrance

    In one corner, put a ladder against the outer wall from the floor up through the ceiling to the surface, and edge the opening with cobblestone.

  5. 5

    Fit out

    Line the hall with barrels, add a crafting table, two furnaces and a chest to the workshop, and bookshelves and a chest to the study. Hang lanterns from the ceiling.

  6. 6

    Hide it

    Cover the ceiling with dirt and grass so only the ladder opening shows.

Builder tips

  • Bring a water bucket in case you dig into lava.
  • Put a trapdoor over the ladder hole to hide it.
  • Hanging lanterns keep the floor clear for storage.
