Blocks and Upgrading

Blocks are the fundamental building units in 7 Days to Die, and nearly everything you construct is assembled from them. Upgrading blocks through material tiers is central to creating a base that can withstand tools, weather, and relentless zombie attacks.

What Blocks Are

Blocks come in many shapes and materials, from full cubes to wedges, ramps, pillars, and stairs. You place them from your inventory after crafting or gathering the necessary materials, then shape and rotate them to fit your design. Different block shapes let you create detailed structures, sloped roofs, and cover positions.

The Upgrade Path

Most structural blocks follow a progression of increasing strength and durability. A common path runs through these tiers:

• Wood frames: cheap, fast to place, and easy to shape, but weak.
• Wood: sturdier than frames and a reasonable early material.
• Cobblestone: a significant durability jump using crushed stone and clay.
• Concrete: strong and craftable once you have a cement mixer.
• Reinforced concrete: near the top tier, ideal for horde-night walls.
• Steel: the strongest common building material, requiring forged steel.

How Upgrading Works

You upgrade a block by hitting it with the correct tool while holding the required resource. Wood frames upgrade with a hammer and wood, while stone and higher tiers typically use a stone axe or nailgun with materials like cobblestone, concrete mix, or forged steel. Each upgrade increases the block's hit points substantially.

Repairing and Downgrading

Damaged blocks can be repaired with the same tool and material used to build them, restoring lost hit points. If a block takes enough damage, it downgrades to a weaker version rather than instantly breaking, giving you a chance to repair before it is destroyed.

Practical Tips

• Place cheap frames first to prototype a layout, then upgrade only what you keep.
• Prioritize upgrading exterior walls and horde-facing surfaces.
• Keep spare materials on hand during blood moons for rapid repairs.
• Higher tiers cost more resources, so balance ambition against your supply of stone, sand, and metal.
