A hidden base dug into the ground. A ladder shaft leads down into a storage hall, with doorways into a workshop with furnaces and a study with bookshelves. Hanging lanterns light every room. The preview is shown with the roof removed.

## Materials

| Block | Count |
| --- | ---: |
| Stone Bricks | 576 |
| Polished Andesite | 169 |
| Barrel | 28 |
| Bookshelf | 6 |
| Ladder | 6 |
| Cobblestone | 5 |
| Lantern | 3 |
| Chest | 2 |
| Furnace | 2 |
| Crafting Table | 1 |

## Build steps

1. Dig: Dig a 15 by 15 pit 7 blocks deep.
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. 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. 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. 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. Hide it: Cover the ceiling with dirt and grass so only the ladder opening shows.

## 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.
