7 Days to Die Base Building Guide — How to Build a Horde-Proof Base

Base Building Principles

Your base must survive wave after wave of zombies. Key principles:

1. Layer your defenses — traps outside, strong walls inside
2. Funnel zombies — force them through chokepoints where your traps/guns are most effective
3. Structural integrity — use reinforced materials, check HP with wrench
4. Vertical advantage — shooting down at zombies from height is much safer

Materials by Strength

Material	HP	Notes
Wood	250	Starter, easily destroyed
Cobblestone	2,000	Mid-game, good initial upgrade
Concrete	5,000	Strong, requires cement
Steel	10,000	End-game, best defense

Upgrade path: Wood → Cobblestone → Concrete → Steel

To upgrade: Hold a repair tool, right-click on a block to upgrade using materials.

Basic Horde Base Design

The Funnel Base

1. Build a rectangular base
2. Leave ONE entrance (funnel point)
3. Fill funnel with barbed wire + spike traps
4. Stand at end of funnel and shoot everything coming through

The Tower Base

1. Build a 5×5 tower, 6+ blocks tall
2. Zombie AI will try to break through the base, not climb
3. Shoot down from the top
4. Add hatches to prevent laddering

Trap Types

Trap	Damage	Notes
Wooden Spikes	Low (slows movement)	Cheap, good early
Iron Barbed Wire	Slows + DoT	Great in funnels
Electric Fence	High	Requires electric system
Dart Trap	Moderate	Automated, uses darts
Blade Trap	High	Great end-game trap

Placement: Place spike traps 5+ deep in your approach path. Zombies take damage the entire walk in.

Base Location

Good locations:

• Open field: 360° visibility, no ambush cover
• Elevated ground: Zombies struggle, you have height advantage
• Near water: Easy access for resource gathering

Avoid:

• Building in trader POI territory (they despawn your stuff)
• Low ground (flooding, poor sightlines)
• Dense forests (hard to spot approaching hordes)

Common Mistakes

• Upgrading inside before outside: Reinforce exterior first
• No escape route: Always have a secondary exit
• Single layer walls: Double-wall everything before Day 7
• Forgetting the roof: Zombies can break through from above too
