Pick a machine and set its current and target level; the Elixir and Laboratory time update straight away. To plan several machines, open Advanced and add each one to the research queue.
Elixir and Laboratory time to take each machine from level 1 to its current max level, before boosts, with the Workshop level and Town Hall that unlock it.
| Machine | Workshop | Unlock | Max level | Elixir, level 1 to max | Lab time |

Data from the Clash of Clans Wiki Workshop and machine tables, cross-checked on 30 October 2026.
The Workshop is upgraded by a builder, not the Laboratory. Each level adds one machine, so the building costs 88,800,000 Elixir and 49 days 12 hours in total across its nine levels.
| Workshop | Needs | Unlocks | Elixir | Build time |
|---|---|---|---|---|
| Workshop 1 | TH12 | Wall Wrecker | 2,400,000 | 2d |
| Workshop 2 | TH12 | Battle Blimp | 3,700,000 | 3d |
| Workshop 3 | TH12 | Stone Slammer | 5,000,000 | 3d 12h |
| Workshop 4 | TH13 | Siege Barracks | 8,700,000 | 4d |
| Workshop 5 | TH13 | Log Launcher | 9,000,000 | 5d |
| Workshop 6 | TH14 | Flame Flinger | 10,000,000 | 5d 12h |
| Workshop 7 | TH15 | Battle Drill | 11,000,000 | 6d |
| Workshop 8 | TH16 | Troop Launcher | 13,000,000 | 7d |
| Workshop 9 | TH17 | Sky Wagon | 26,000,000 | 13d 12h |
Workshop 9 alone costs 26,000,000 Elixir and 13 days 12 hours, twice the Elixir of Workshop 8.
The Sky Wagon is the latest addition to the Workshop and the only one locked behind Workshop 9 at Town Hall 17. It has just three research levels, but every one of them costs more than any level of the older machines except their final ones.
| Sky Wagon level | Elixir | Lab time | Laboratory | Town Hall |
|---|---|---|---|---|
| 1 (Workshop 9 unlock) | 26,000,000 (building) | 13d 12h (builder) | — | TH17 |
| 2 | 22,000,000 | 10d | 15 | TH17 |
| 3 | 26,000,000 | 13d 12h | 16 | TH18 |
| 4 (max) | 29,000,000 | 16d | 16 | TH18 |
All Laboratory research shares one queue and, for Elixir research, one storage. Siege Machines are the smallest of the three Elixir research lists:
| Research | Elixir, level 1 to max | Lab time |
|---|---|---|
| 19 Elixir troops | 1,532,595,000 | about 1,478 days (all 32 troops) |
| 10 Elixir spells | 586,975,000 | about 684 days (all 18 spells) |
| 9 Siege Machines | 490,700,000 | 315 days 12 hours |
Most machines' last level needs Laboratory 16, so the final levels usually wait until Town Hall 18.
My game progress (MoonLight ID #9280QPL8G): I play mostly ground attacks, so Siege Barracks goes into nearly every army. It is one level short of max, but it sits at the bottom of my upgrade list because my clanmates can always fill my Clan Castle with a maxed one. My advice: upgrade the Workshop or unlock a new machine only when no one in your clan donates them. Until then, and especially at Town Hall 10 or 11 when you can't build them yourself, put your Elixir into the main troops of your primary and secondary armies.
Siege Barracks has 5 upgrades, level 1 to 6: 61,500,000 Elixir and 41 days of Laboratory time without boosts. Level 6 alone costs 27,000,000 Elixir and takes 15 days.
Sky Wagon: 77,000,000 Elixir and 39 days 12 hours for just 3 paid levels after it unlocks at level 1. Its last level costs 29,000,000 Elixir.
Elixir. Every Siege Machine level and every Workshop level is paid with Elixir.
No. The Workshop level only unlocks each machine. Higher machine levels are researched in the Laboratory.
Wall Wrecker, Battle Blimp and Stone Slammer at TH12, Siege Barracks and Log Launcher at TH13, Flame Flinger at TH14, Battle Drill at TH15, Troop Launcher at TH16 and Sky Wagon at TH17.
