Extra Concrete
Extra Concrete adds slabs, stairs and other concrete variants for the Forge and NeoForge loaders, covering the full set of concrete colors in Minecraft.
What it does
Extra Concrete gives each concrete color extra block shapes, including slabs and stairs, along with new blocks that extend the vanilla set. Crafting recipes for the new variants are added by the mod, so they can be made from ordinary materials without commands. Concrete slabs and stairs are usable as building parts in the same way as other decorative blocks.
Installation is needed on both sides: the server and every player must run the mod. Builds are published for Forge and NeoForge only, covering 1.20.1 and 1.21.1, with 0.1.0 for 1.20.1 and 0.1.1 for 1.21.1 as the latest files. The code is not open source, and the mod is released under All rights reserved.
Key features
Concrete slabs
Each concrete color gains a slab, so a single block can be used as a half-height step or a flat surface.
Concrete stairs
Stair shapes are added for the concrete colors, giving builders sloped edges without carving vanilla blocks.
New concrete blocks
Additional concrete block forms extend the vanilla set for building colored walls and floors.
Color support
The variants follow the existing concrete colors, so the new shapes match the palette players already use.

Use cases
Colored floors and walls
Slabs and stairs in matching colors let builders finish a floor or wall edge without mixing block sources.
Who it’s for: Builders who work with concrete colors and want slab and stair shapes for each one. Server owners can add it to a world that already uses concrete decoration.
