Omniaxis Construction Mod (1.21.11, 1.21.1) – Build Custom Walls with Vertical

September 5, 2026

Available for:

Omniaxis Construction Mod expands your building palette with sideways stairs, vertical slabs, and hundreds of block shapes. The mod introduces over 300 new stair variants crafted from standard building, colored, and natural blocks. Blocks keep their special traits, so ice stairs stay slippery and leaf stairs never decay. You can craft these pieces on regular crafting tables or shape them quickly with stonecutters.

Features:

Adds 311 standard stair variants crafted from building blocks, colored blocks, and natural materials.
Includes 56 custom sideways stair and 59 vertical slab variants remade from vanilla block types.
Preserves unique block properties so ice stairs remain slippery and soul sand stairs slow movement.
Keeps leaf and farmland stairs permanently stable so they never decay, dry out, or turn to dirt.
Wooden pieces naturally catch fire, burn away, and work as furnace fuel.
Stone variants require the correct pickaxe tier to break and harvest properly.
Sorts all added pieces into dedicated creative inventory tabs for quick access during building.
Offers quick crafting recipes through standard crafting tables and stonecutters.

How to Use:

Place regular stone stairs or slabs into a stonecutter to cut them into sideways stairs or vertical slabs.
Craft wooden and soft stairs, such as dirt or froglight variants, using standard crafting tables.
Open the creative inventory to find the Sideways Stairs, Vertical Slabs, and Vanilla+ Stairs tabs.
