BH1 is where every Builder Base starts, so it has no cost.

Where the Time Goes

The first three upgrades, BH2 to BH4, take 1 day 1 hour 5 seconds in total. After that, each Builder Hall takes one day longer than the one before.

BH2 and BH3: minutes, not days

BH2 costs 3,500 Builder Gold and finishes in 5 seconds. BH3 costs 30,000 and takes 1 hour.

BH4 to BH7: the steady climb

1 to 4 days each and 3,600,000 Builder Gold together. This is where the Builder Base starts to need real farming.

BH8 to BH10: 18 days and 11.4 million Gold

The last three halls cost 2,800,000, 3,800,000 and 4,800,000 Builder Gold, about three quarters of the whole total.

Upgrade Work Added at Each Builder Hall

Each row shows only the new upgrade work a Builder Hall level opens: the buildings, traps, walls and Star Laboratory levels added at that tier. Rows are not running totals. To max a base from scratch, add every row up to your Builder Hall; the last row adds all tiers together.

From BH7, walls can be paid with Builder Gold or Builder Elixir. Data from the Clash of Clans Fandom wiki, checked 31 October 2026.

Builder Base Update History

  • May 2017: the Builder Base launches with the Builder Hall and the Master Builder.
  • May 2023: Supercell announces Builder Base 2.0 and Builder Hall 10, with the X-Bow and the Electrofire Wizard (BH10 costs 4.8 million Builder Gold and 7 days).
  • 31 October 2026: this page published, with every Builder Hall level checked against the Clash of Clans Fandom wiki.

Planning Builder Hall Upgrades

  • Max the base before the next hall. A new Builder Hall only raises caps; the real cost is in the buildings it unlocks.
  • Keep the Master Builder busy. From BH4 every hall takes days, so start it right after a long batch of defenses finishes.
  • Plan Builder Elixir separately. The hall uses Builder Gold, while troops and the Star Laboratory use Builder Elixir, so you can run both at once.
  • Each hall raises the hero caps too. BH5 repairs the Battle Machine and BH8 unlocks the Battle Copter; both reach level 35 at BH10.
  • Use walls to burn spare loot. From BH7, walls take either resource, a good way to use storage that would otherwise overflow.

On my Builder Base, Dark Knight (ID #82GY00YYQ): the Builder Hall is at BH10, but the base isn't finished yet. The Battle Copter is at level 22, 13 levels from max, and these are still below max: 4 Firecrackers, 1 Gold Mine, 3 Mega Mines, 3 Mines (two at level 9, one at level 5), 4 Spring Traps and 4 Push Traps. With 13 Battle Copter levels to go, that's what I'll upgrade next.
