The CoC Builder Base is the second village in Clash of Clans, and learning how it works is one of the fastest ways to grow your account. This complete guide explains what the Builder Base is, how to unlock it, how to upgrade your Builder Hall, how Versus Battles work, and how to chase the prized free sixth builder. Whether you just hit the requirement or you returned to a long-dormant account, you will know exactly what to do next.
The Builder Base shares your account but almost nothing else with the Home Village. It has separate buildings, troops, defenses, and a separate gold and elixir economy, so progress here does not slow your main village down. Below we break everything into clear sections, each with a diagram.
What you need before starting
- Town Hall level 4 or higher in your Home Village.
- A short, one-time boat repair to open the new island.
- A few minutes a day for Versus Battles, which fuel almost all of your Builder Base growth.

Step 1: Understand what the Builder Base is
When you reach the requirement, a wrecked boat appears at the edge of your Home Village. Repairing it reveals a brand-new island known as the Builder Base. Think of it as a parallel village: it has its own Builder Hall (instead of a Town Hall), its own unique troops, and its own defenses and resources. Nothing you spend or earn here touches your main village, so you can experiment freely.

Step 2: Unlock the Builder Base by repairing the boat
Once your Town Hall is level 4 or higher, look for the broken boat near the shoreline of your Home Village. Tap it and choose Repair. The repair is quick and free, and as soon as it finishes you can sail across to the Builder Base. The Master Builder greets you and helps place your first Builder Hall.

Step 3: Build and upgrade your Builder Hall
The Builder Hall is the heart of this village, just as the Town Hall is for your main base. Its level decides which defenses, troops, traps, and storages you can build, and how many of each you may place. Keep the Builder Hall reasonably matched to your defenses rather than rushing it — a balanced base wins more Versus Battles, which in turn pays for the next upgrade.

Step 4: Win Versus Battles for trophies and loot
Versus Battles are the main game mode of the Builder Base. You attack an opponent's base while they attack a copy of yours, and the higher destruction percentage wins. Winning awards more trophies and, importantly, a daily win bonus of gold and elixir — usually your biggest single source of resources here. You can attack repeatedly, but the rich win bonus is limited to a few wins per day, so aim to actually win those.

Step 5: Work toward the 6th Builder (O.T.T.O)
The long-term goal of the Builder Base is the O.T.T.O Hut, which gives you a permanent, free sixth builder that helps in both villages. To earn it you complete a set of upgrade tasks — such as raising specific defenses and your Battle Machine to certain levels and reaching Builder Hall 9. It takes time, but a sixth builder lets you run two upgrades at once, so it pays off for the rest of your account's life.
Finish the O.T.T.O tasks to claim a permanent sixth builder.
Tips to progress faster
- Always claim your win bonus. The daily wins are worth far more loot than extra attacks, so prioritize securing them.
- Keep a builder busy. Idle builders are wasted time — queue an upgrade before you log off.
- Use the Clock Tower. Boost it to speed up everything in the Builder Base for a short window, ideally right before a big upgrade.
- Don't rush the Builder Hall. Upgrading defenses and troops alongside it keeps your win rate high and your loot flowing.
- Learn one solid attack. A reliable troop combination for your Builder Hall level wins more consistently than random pushes.
Troubleshooting
I can't find the boat
The boat only appears once your Home Village Town Hall is level 4 or higher. Check the outer edge of your village near the water; if your Town Hall is below level 4, upgrade it first.
My Versus Battles feel impossible
You may have rushed your Builder Hall ahead of your defenses, which raises the strength of opponents you face. Spend a few days upgrading defenses and troops to your current Builder Hall level before pushing trophies again.
The win bonus is greyed out
The large win bonus is limited per day and refreshes on a timer. Once you have used your daily wins, you can still attack for trophies, but the big loot reward returns after the reset.
Frequently asked questions
What level do you need to unlock the Builder Base?
Your Home Village Town Hall must be level 4 or higher. After that, repair the boat at the edge of your village to sail to the Builder Base.
Is the Builder Base separate from my main village?
Yes. It has its own buildings, troops, defenses, and resources. Spending or earning there does not affect your Home Village economy.
How do I get more loot in the Builder Base?
Win Versus Battles. Your daily win bonus of gold and elixir is the main resource source, so focus on securing those limited daily wins.
What is O.T.T.O and how do I unlock the 6th builder?
O.T.T.O is an extra builder you earn by completing Builder Base upgrade tasks, including reaching Builder Hall 9 and leveling specific buildings. Once unlocked, the sixth builder helps in both villages.
Should I rush my Builder Hall?
No. Keep defenses and troops near your Builder Hall level. A balanced base wins more battles and earns loot faster than a rushed one.
Final thoughts
The CoC Builder Base rewards steady, balanced play: unlock it by repairing the boat, grow your Builder Hall in step with your defenses, secure your daily Versus Battle wins, and chase the O.T.T.O sixth builder for a permanent boost. Stick to those fundamentals and your second village will quietly become one of the most valuable parts of your account. For official updates and patch notes, see the official Clash of Clans site.
