Vanilla Minecraft walls only snap together at 90-degree angles, which limits what builders can do with castles, curved pathways, and organic-looking structures. Diagonal Walls Mod removes that restriction by letting walls connect diagonally, opening up a whole new layer of architectural creativity. It also extends diagonal connections to fences and glass panes, so your builds stay visually cohesive. With over 2.2 million downloads and active updates through late 2025, it has become a staple in many builders' mod lists.
Key Features
- Diagonal wall connections — Walls now snap together at angles beyond the standard 90 degrees, enabling complex shapes like turrets, angled fortifications, and curved garden borders that were previously impossible.
- Fence and glass pane support — The diagonal behavior extends to fences and glass panes, so you can build matching diagonal fences alongside your walls without visual breaks or misaligned connections.
- Vertical connection control — Vertical connections are intentionally disabled, which creates natural gaps when stacking walls. This design choice allows for decorative openings and arrow slits in castle builds.

FAQ
Does Diagonal Walls Mod work with all wall types?
The mod applies diagonal connections to standard walls, fences, and glass panes. It should work with vanilla wall variants, though compatibility with walls added by other mods may vary.
Why are there gaps when I stack walls on top of each other?
This is intentional — vertical connections are disabled by design. The gaps can actually be used creatively for arrow slits, ventilation openings, or decorative patterns in castle walls.
Can I use Diagonal Walls on a multiplayer server?
The mod needs to be installed on both the server and all connecting clients for the diagonal connections to display and function correctly.
