Updated for Town Hall 18 (October 2026).
The Builder Hall is the main building of the Builder Base, the same job the Town Hall does in your Home Village: its level decides what you can build and how far you can upgrade it. The highest level is Builder Hall 10, added with Builder Base 2.0 on May 15, 2023, and it is still the max in October 2026. Destroying it gives an attacker the first star on Stage 1 of a Builder Base battle.
What the Builder Hall does
- It caps the level and number of every other Builder Base building, trap and wall.
- It is the star building for Stage 1. Knocking it down earns the attacker 1 Bronze Star. From Builder Hall 6, Stage 2 has its own star building, O.T.T.O’s Outpost.
- It holds some Builder Gold and Builder Elixir of its own, from 50,000 of each at level 1 to 1,500,000 of each at levels 9 and 10.
- The Master Builder lives inside it. The Builder Base has no Builder’s Huts, so the Builder Hall is his home.
You reach the Builder Base by repairing the Boat on your Home Village shore, which a new account can do from Town Hall 6. You arrive at a wrecked Builder Hall 1 surrounded by ruined buildings and graves. The tutorial takes it to level 2 and repairs the buildings around it, apart from the Gem Mine, Clock Tower and the Battle Machine, which you repair later.
Builder Hall levels: cost, time and hitpoints
| Builder Hall | Hitpoints | Upgrade cost (Builder Gold) | Upgrade time | Builder Gold and Elixir it stores (each) |
|---|---|---|---|---|
| 1 | 650 | Ruin | None | 50,000 |
| 2 | 800 | 3,500 | 5s | 75,000 |
| 3 | 975 | 30,000 | 1h | 100,000 |
| 4 | 1,150 | 200,000 | 1d | 150,000 |
| 5 | 1,350 | 400,000 | 2d | 900,000 |
| 6 | 1,600 | 1,200,000 | 3d | 900,000 |
| 7 | 1,850 | 1,800,000 | 4d | 1,100,000 |
| 8 | 2,150 | 2,800,000 | 5d | 1,300,000 |
| 9 | 2,450 | 3,800,000 | 6d | 1,500,000 |
| 10 | 2,750 | 4,800,000 | 7d | 1,500,000 |
You cannot start the next Builder Hall upgrade until you have placed every building your current level allows. The Gem Mine, Clock Tower and Battle Machine are the exceptions, since repairing those is optional.
What each Builder Hall level unlocks
| Builder Hall | New buildings, defenses and traps |
|---|---|
| 1 | Ruined Cannon, Gold Mine, Elixir Collector, Army Camp, Builder Barracks and Star Laboratory (all repaired in the tutorial); 10 walls |
| 2 | Archer Tower, Double Cannon, Push Trap |
| 3 | Hidden Tesla, Firecrackers, Crusher, Gold Storage, Elixir Storage, Spring Trap, Mine; Gem Mine can be repaired |
| 4 | Guard Post, Air Bombs, Mega Mine; Clock Tower can be repaired |
| 5 | Multi Mortar; the Battle Machine can be repaired |
| 6 | Stage 2 opens: O.T.T.O’s Outpost, Reinforcement Camp, Healing Hut; Roaster |
| 7 | Giant Cannon |
| 8 | Mega Tesla, Battle Copter |
| 9 | Lava Launcher, B.O.B Control, second Reinforcement Camp |
| 10 | X-Bow, Electrofire Wizard; most buildings go to level 10 |
Most buildings and traps max out at the same level as your Builder Hall. The exceptions include the Builder Barracks (12 levels), the Healing Hut (6), the X-Bow and B.O.B Control (5 each), and the two hero machines (35).
Builder Hall 6 and the two-stage base
Builder Hall 6 is the big step. Up to level 5, the Builder Base is one small village. From Builder Hall 6, a cave on the west side opens onto a second stage with its own central building, O.T.T.O’s Outpost. Attacks become two rounds: the attacker clears Stage 1 for up to 3 Bronze Stars, and surviving troops move on to Stage 2 for up to 3 Silver Stars, for a maximum of 6 stars and 200%.
Each stage has a limit on how many defenses, traps and walls it can hold. At Builder Hall 10 that is 14 defenses, 12 traps and 100 walls per stage. You choose which defenses go where; storages and other non-defense buildings have fixed spots on each stage. O.T.T.O’s Outpost is not counted as a defense and always sits on Stage 2. The Builder Base 2.0 guide covers the stage system and the star rewards in full.
Builders in the Builder Base
- The Master Builder works from the start.
- O.T.T.O becomes a permanent second builder when you reach Builder Hall 6.
- Since May 26, 2026, B.O.T.O’s Shack adds one more Builder Base builder. It appears from Builder Hall 2, costs 1,000 Gems, and can only be built once you have all five Home Village Builder’s Huts.
- B.O.B is the robot you unlock through B.O.B Control at Builder Hall 9, but he works in the Home Village as its sixth builder, not on the Builder Base.
Where to place the Builder Hall
Put it in the middle of Stage 1 with your strongest defenses around it. Stars count before destruction percentage, and a player who reaches the Builder Hall will usually have passed 50% on the way, which hands them two stars. Its high hitpoints buy your defenses extra shots, so make sure several of them cover it.
A Crusher next to it punishes ground troops that walk in, but back it up with longer-range defenses so ranged troops cannot pick the Crusher off from outside its reach. Do not bother hiding the Hall in a walled corner: attackers can still drop troops right next to it.
An anti-three-star Stage 1 is also worth a try. If the attacker never clears Stage 1, there is no Stage 2 fight at all, and you keep more Builder Elixir from the defense.
Should you rush the Builder Hall?
Usually not. Upgrade everything you can before the next Builder Hall. A rushed Hall leaves you with low-level troops and defenses that take a long time to catch up, and attacking with weak troops gets harder at every level. The one good reason to push ahead is B.O.B: his tasks at Builder Hall 9 unlock a permanent sixth builder for your Home Village.
