How to Upgrade Building Blocks in 7 Days to Die

Building a strong base is essential in 7 Days to Die, and upgrading your building blocks is one of the best ways to increase durability and protection against zombie attacks. This guide will walk you through the complete process of crafting and upgrading building blocks from the basic plank stage all the way to forged steel—the strongest tier available.

Crafting Your First Building Blocks

To get started, you’ll need to craft building blocks. These are found under the Basics category in your crafting menu and require only 2 wood to craft. This makes them extremely affordable and easy to produce early in the game.

Once you have crafted your building blocks, you can place them by right-clicking in the game world. When a block is ready to be placed, it will appear white. If the block appears red or pink, this means it lacks proper support and cannot be placed. Ensure that any block you place is connected to an existing structure for stability.

The Upgrade System Explained

To upgrade your building blocks, you’ll need one of three tools:

Stone Axe

Claw Hammer

Nail Gun

You must also have the appropriate upgrade material in your inventory. The upgrade process requires multiple right-clicks on the block with your chosen tool until it transforms into the next tier.

Upgrade Progression: From Plank to Forged Steel

Stage 1: Wood (Plywood)

Your building blocks start as wooden planks. This is the base tier and provides minimal protection. To upgrade to the next stage, you simply need wood in your inventory—you should have plenty from basic resource gathering.

Stage 2: Cobblestone

After upgrading with wood, your next tier is cobblestone. You can obtain cobblestone by mining stone blocks in the world. With your tool equipped and cobblestone in your inventory, right-click the wood block multiple times until it transforms into cobblestone.

Stage 3: Concrete

Once your blocks are cobblestone, you can upgrade them further to concrete. This is a significant step up in durability. Keep your tool equipped and concrete in your inventory, then right-click multiple times to complete the upgrade.

Stage 4: Forged Steel (Final Tier)

The final and most durable upgrade tier is forged steel. To reach this stage, you’ll need steel bars (also called forged steel) in your inventory. With your tool equipped, right-click the concrete blocks multiple times to transform them into forged steel blocks. This is the highest tier available and offers maximum protection for your base.

Summary

Upgrading your building blocks in 7 Days to Die is a straightforward process that significantly improves your base’s durability. The progression chain is: Wood (Plywood) → Cobblestone → Concrete → Forged Steel. Ensure you have the correct tool (Stone Axe, Claw Hammer, or Nail Gun) and the upgrade material in your inventory, then right-click multiple times until the block transforms. Start with basic wood blocks and gradually upgrade to forged steel for the ultimate fortress protection against the undead hordes.
