About Underground Base Schematics

An underground base is built into the ground or a hillside instead of on top of it. It is hidden from other players, safe from creepers outside and easy to expand by digging new rooms, which makes it a popular choice for survival worlds and multiplayer servers.

The extra step compared with a surface house is excavation. Check the dimensions to see how large an area you need to dig out, and use the 3D preview to see where the entrance meets the surface. Litematica's layer view is useful here: you can dig and build one level at a time, and see exactly where the walls and floors go.

Caves are dark, so hostile mobs spawn anywhere the block light level is 0, including inside a half-finished base. Light up the rooms as you dig them out. If you build very deep, below Y 0, avoid the deep dark: sculk shriekers there can summon the Warden.

Frequently asked questions

How do I build an underground base from a schematic?
Load the .litematic file in Litematica and place it where you want the base. Dig out the area the schematic shows, then use the layer view to build one level at a time. The materials list covers the blocks you place, not the blocks you dig out.
How do I stop mobs spawning in an underground base?
Hostile mobs spawn where the block light level is 0, so light up every room and corridor as you dig it, and seal off any connected caves. The spawn-proofing calculator helps you space your lights.
Can other players find an underground base?
It is much harder to spot than a surface build, but not invisible. A hidden entrance helps, and many of these schematics include one. Check the 3D preview to see how the entrance meets the surface.
