Features

56 Custom Stair & 59 Vertical Slab Variants

Every single vanilla stair and slab type from Minecraft 1.21.x has been completely remade to support sideways and vertical placement!

Full Material Spectrum

Built with all standard materials including classic Wood variants (Oak, Spruce, Cherry, Bamboo, etc.), Stone & Brick types (Cobblestone, Deepslate, Quartz, Nether Bricks), and dynamic Copper blocks (including exposed, weathered, and oxidized variants).

Custom Creative Tabs

All new blocks are neatly organized inside their own dedicated tabs (Sideways Stairs and Vertical Slabs) in the Creative Inventory for fast and easy access while building.

Vanilla Fire & Tool Behavior

Wooden variants naturally catch fire and burn away, and act as a balanced fuel source in furnaces. Stone variants integrate flawlessly with pickaxe tier requirements, while stone and copper remain completely fireproof.

Crafting Guide

To keep your survival experience perfectly balanced, every single block can be crafted at a fair 1-to-1 ratio! You can craft 1 Sideways Stair or 1 Vertical Slab directly from its standard vanilla variant.

1. Stonecutter

The fastest way to get sideways stairs or vertical slabs is by using the standard vanilla Stonecutter. Just place any regular stone stair or slab inside to slice it into its custom counterpart!

2. Crafting Table

You can also easily convert blocks back and forth using standard crafting grids.
