Building on Extreme Terrain and Tall Mountains

Understanding the New Height Range

The mod extends the world from Y -256 to Y 1664, giving you vastly more vertical space to build. Mountains now reach much higher than vanilla peaks, creating dramatic building sites with sweeping views.

Choosing Your Build Location

Scout mountain ranges and stony shores for natural cliff formations. The mod generates taller peaks with steeper slopes, so plan your base around existing terrain rather than fighting it. High elevations offer natural defense and spectacular vistas.

Consider building into cliff faces rather than on top—you can carve out rooms from stone and use the natural walls as structure.

Managing Construction at Height

Bring scaffolding or blocks for temporary platforms when building above Y 256. The thin air at extreme heights doesn't change gameplay, but falling is more dangerous. Use water buckets for safe descent during construction.

Take advantage of the larger biomes—you'll have consistent terrain around your build site without sudden biome changes interrupting your design.
