Updated for Town Hall 18 (October 2026).
The Workshop is the Home Village army building that builds Siege Machines, the vehicles that carry your Clan Castle troops into a base. It unlocks at Town Hall 12, and each upgrade adds a new Siege Machine. Level 9, released on April 27, 2026, is the current max: it needs Town Hall 17 and unlocks the Sky Wagon, the ninth Siege Machine.
What the Workshop does
Siege Machines are built here for free and instantly, the same way troops and spells are now. You choose which machine to bring when you plan your army, and you can only deploy one per battle. When you deploy it, your Clan Castle troops ride inside and come out when the machine is destroyed or reaches its goal, so the machine decides where your reinforcements enter the fight.
A few rules worth knowing:
- The Workshop keeps building while it’s being upgraded, with no penalty.
- Losing your Workshop on defense doesn’t touch your built machines.
- Siege Machine levels are researched in the Laboratory with Elixir, not in the Workshop.
- Clanmates can donate Siege Machines to you once your Clan Castle is level 6 or higher, which lets players below Town Hall 12 use them too.
Workshop levels and the Siege Machine each unlocks
The Workshop is a 4×4 building and you get one. Capacity is how many machines it can hold ready at once.
| Level | Unlocks | Capacity | Hitpoints | Cost (Elixir) | Upgrade time | Town Hall needed |
|---|---|---|---|---|---|---|
| 1 | Wall Wrecker | 1 | 1,000 | 2,400,000 | 2d | 12 |
| 2 | Battle Blimp | 2 | 1,100 | 3,700,000 | 3d | 12 |
| 3 | Stone Slammer | 3 | 1,200 | 5,000,000 | 3d 12h | 12 |
| 4 | Siege Barracks | 3 | 1,300 | 8,700,000 | 4d | 13 |
| 5 | Log Launcher | 3 | 1,400 | 9,000,000 | 5d | 13 |
| 6 | Flame Flinger | 3 | 1,500 | 10,000,000 | 5d 12h | 14 |
| 7 | Battle Drill | 3 | 1,600 | 11,000,000 | 6d | 15 |
| 8 | Troop Launcher | 3 | 1,700 | 13,000,000 | 7d | 16 |
| 9 | Sky Wagon | 3 | 1,800 | 26,000,000 | 13d 12h | 17 |
Base costs and times, before Gold Pass discounts. Town Hall 18 has no new Workshop level; the max stays at 9.
Which Siege Machine to pick
Each machine delivers your Clan Castle troops in its own way, so the right pick depends on the army behind it. They split into three groups.
Machines that head for the Town Hall:
- Wall Wrecker drives along the ground toward the Town Hall, breaking Walls and buildings in its way.
- Battle Blimp flies straight at the Town Hall and drops bombs on the way, so it suits air armies or a planned Clan Castle drop in the core.
- Log Launcher also rolls toward the Town Hall, firing a log every three seconds that travels up to 20 tiles or until it has hit four buildings.
Machines that hunt defenses:
- Stone Slammer flies from defense to defense, hitting like a very tough Balloon with wide splash. It fits Lava Hound and Balloon attacks.
- Flame Flinger stays back and lobs fire at defenses from range, leaving burning ground that keeps dealing damage.
- Battle Drill burrows under Walls to a defense, stuns defenses around it when it surfaces, then digs on to the next one.
- Sky Wagon flies toward defenses and launches up to six barrels, each holding Minions, a Balloon, a Baby Dragon and a Clan Castle troop. It works best behind your air troops.
Machines that add troops where you choose:
- Siege Barracks parachutes in, then spawns P.E.K.K.As and Wizards at your researched levels before releasing your Clan Castle troops.
- Troop Launcher can’t move. It fires barrels of Barbarians, Archers, Giants, Wall Breakers and one Clan Castle troop at spots where your army is already fighting.
Since you bring a machine to nearly every war attack, research the one your main army uses before the others.
