A building-focused Minecraft mod that adds functional vertical slabs for a wide variety of vanilla blocks.
Unlike normal slabs, which divide a block horizontally, this mod allows blocks to be placed as vertical halves, greatly expanding the possibilities for detailed building.
Use them for thin walls, pillars, window frames, decorations, detailed façades, and many other structures that are difficult to create with vanilla blocks alone.
The goal of this mod is not simply to make blocks look like vertical slabs. Wherever possible, vertical slabs retain the appearance, properties, sounds, interactions, and special behavior of their original vanilla blocks.
A large number of vanilla building, natural, decorative, and functional blocks are available as vertical slabs.
Where possible, the mod references Minecraft's existing block textures instead of duplicating them, helping vertical slabs remain visually consistent with vanilla Minecraft and compatible resource packs.
Support continues to expand as development progresses.
Vertical slabs can be placed on either half of a block space, allowing much more precise control when building.
Two compatible vertical halves can also occupy the same block space, allowing structures to be built naturally without requiring awkward workarounds.
Placement behavior is designed to feel as close to vanilla slab placement as possible.
Different placement modes are available to make building with vertical slabs easier.
These modes reduce the need to constantly switch blocks while constructing larger builds and provide more control over how slabs are positioned.
Supported slabs can be converted between their normal horizontal form and their vertical form.
This makes it easier to switch building styles without repeatedly crafting different variants.
Compatible stone-based vertical slabs can be crafted using the Stonecutter.
Stonecutter recipes are generally only added where the corresponding vanilla block already makes sense as a stonecutting material, keeping the system consistent with vanilla Minecraft.
Vertical slabs are not limited to decorative blocks.
Where technically possible, this mod attempts to reproduce the behavior of the original block even after it has been converted into a vertical slab.
Supported functionality includes features such as:
The long-term goal is for a vertical slab to behave as much like its full-block counterpart as reasonably possible.
Copper vertical slabs support Minecraft's copper mechanics where applicable.
This includes:
Some specialized copper blocks, including Redstone-related blocks such as Copper Bulbs, are also supported.
Vertical variants of transparent and translucent blocks are also included.
This includes blocks such as:
Rendering is adjusted where necessary to keep them looking as close as possible to their vanilla equivalents.
Certain vanilla blocks have visuals that cannot be reproduced correctly by simply cutting their model in half.
The mod therefore includes additional handling for blocks such as biome-colored blocks and blocks with different textures on individual faces.
Examples include:
This helps avoid the common problem of vertical slabs looking like simple stretched or incorrectly cropped versions of the original block.
Several functional vertical slabs interact with Redstone.
Depending on the original block, vertical versions may:
Support varies depending on the original Minecraft block and continues to improve with updates.
Just Enough Items (JEI) is supported but is not required.
When JEI is installed, vertical slabs can be searched more easily.
Search aliases are provided for terms such as:
vertical
vertical slab
縦
縦ハーフ
Additional aliases are included for supported languages where possible.
This allows players using different Minecraft languages to find the same blocks without needing to know their internal English names.
The mod provides a dedicated Creative Mode tab containing its vertical slabs.
Supported blocks may also appear alongside related vanilla blocks in appropriate Creative Mode categories.
The dedicated tab can be disabled through the mod configuration if you prefer a cleaner Creative inventory.
Several features can be adjusted through the mod configuration.
Depending on the version, configurable options may include:
※In the Fabric version, you can open the settings screen by pressing the F8 key.
Additional configuration options may be introduced in future updates.
The main goal of this mod is:
To make vanilla Minecraft blocks usable as vertical slabs without unnecessarily removing the features that make those blocks unique.
Rather than creating hundreds of purely decorative copies, the mod aims to preserve as much vanilla behavior as reasonably possible.
That includes block properties, Redstone behavior, sounds, lighting, particles, interactions, oxidation, biome coloring, and other special mechanics.

JEI is recommended for easier searching and recipe viewing, but it is not required for the mod to function.
This mod is actively developed.
Because Minecraft contains many blocks with unique rendering and gameplay behavior, some vertical slabs may still behave differently from their full-block counterparts.
New blocks, compatibility improvements, bug fixes, and additional vanilla behavior are planned for future updates.
