Clash of Clans’ Builder Base offers a unique layer of strategy, and Builder Hall 9 (BH9) represents the peak of both defensive and offensive gameplay. A well-crafted BH9 base uses the two-stage layout to slow down attackers, protect key structures, and secure victory in Versus Battles. This guide covers everything you need to know about designing a powerful Builder Hall 9 base, from layout principles and defensive priorities to trap placement and meta counters.

Understanding the Two-Stage Builder Hall 9 Base
At BH9, your base is divided into Stage 1 and Stage 2. Opponents must first clear Stage 1 before progressing to Stage 2, and the combined destruction percentage determines the winner. A strong Builder Hall 9 base balances both stages, ensuring each phase complements the other while exhausting enemy troops.
Key Objectives for a BH9 Base Design
- Delay and Distract: Slow attackers to maximize defensive damage.
- Counter Meta Strategies: Prepare for ground spam, air rushes, and hybrid attacks.
- Protect the Builder Hall: Keep the Builder Hall central and well-guarded.
- Trap Synergy: Place traps to disrupt troop paths and punish attackers.
Stage 1: The First Line of Defense in a Builder Hall 9 Base
Stage 1 is designed to weaken the enemy’s army and make Stage 2 harder to clear. A good BH9 base ensures attackers spend troops and abilities early.
Core Layout Principles
- Central Builder Hall: Protect the Builder Hall with high-HP structures like the O.T.T.O Hut and storages.
- Compartmentalization: Create 4–6 compartments to slow troops.
- Defensive Coverage: Overlap ranges of Lava Launcher, Mega Tesla, and Roaster for kill zones.
Defensive Prioritization
- Lava Launcher: Strong vs. ground spam—keep it central.
- Mega Tesla: Place where it can’t be easily sniped.
- Roaster: Perfect for stopping Baby Dragons or Night Witches.
- Crusher + Guard Post: Use Crushers in choke points, supported by Guard Post troops.
Trap Placement
- Push Traps to redirect into Crushers.
- Spring Traps along common troop paths.
- Mines and Mega Mines near air approaches or Battle Machine paths.
Stage 2: The Final Stand of a BH9 Base
If attackers clear Stage 1, Stage 2 must finish them off. This stage should protect remaining percentages and make 2-stars difficult.
Core Layout Principles
- Asymmetrical Design: Break attacker expectations with irregular walls.
- High-HP Buffers: Place storages around key defenses.
- Funneling Paths: Guide troops into traps and kill zones.
Defensive Prioritization
- Lava Launcher + Mega Tesla: Cover critical areas.
- Air Bombs + Firecrackers: Stop air-heavy attacks.
- Giant Cannon: Target the Battle Machine and tanks.
Trap Placement
- Push Traps to separate troops.
- Mines near air defenses.
- Mega Mines for late-stage pushes.
Countering Meta Attacks at Builder Hall 9
- Ground Spam (Raged Barbarians, Boxer Giants): Use Crushers, Spring Traps, and centralized Lava Launcher.
- Air Rush (Baby Dragons, Night Witches): Prioritize Roaster, Air Bombs, and Firecrackers.
- Hybrid Attacks (Battle Machine + Mix): Use Push Traps and Giant Cannon to separate and punish units.
Advanced Tips for a Strong Builder Hall 9 Base
- Test and adapt layouts with Friendly Challenges.
- Spread storages across both stages.
- Protect O.T.T.O Hut and Clock Tower as buffers.
- Mix trap placements to surprise attackers.
Common Mistakes in BH9 Base Building
- Overloading Stage 1: Leaves Stage 2 too weak.
- Predictable Traps: Make placements less obvious.
- Ignoring Air Defense: Air spam is common—always prepare.
- Weak Funnel Design: Ensure walls guide troops into kill zones.
What is the best Builder Hall 9 base layout?
The best Builder Hall 9 base layout balances defenses across both stages. Stage 1 should weaken the enemy with Crushers, Lava Launcher, and traps, while Stage 2 uses Mega Tesla, Roaster, and Giant Cannon to finish off the remaining troops.
How do I defend against air attacks in a BH9 base?
To stop Baby Dragons and Night Witches, position Air Bombs, Firecrackers, and the Roaster strategically in your BH9 base. Mines and Mega Mines also help eliminate swarms of air troops.
Should I focus more defenses in Stage 1 or Stage 2 of a Builder Hall 9 base?
Neither stage should be overloaded. Stage 1 should drain enemy resources, while Stage 2 acts as the finishing layer. A balanced Builder Hall 9 base splits defenses effectively to avoid weaknesses.
How often should I update my Builder Hall 9 base design?
Update your BH9 base whenever new attack strategies dominate the meta. Regularly test layouts in Friendly Challenges to find weaknesses and adjust trap placements.
Conclusion
A successful Builder Hall 9 base balances strong Stage 1 defenses with a resilient Stage 2 to counter any army composition. By optimizing trap synergy, defensive coverage, and resource distribution, you can build a BH9 base that frustrates attackers and wins Versus Battles. Keep testing, refining, and adapting to stay ahead of the meta. Feel free to copy this base layout,
