How production buildings work

Production buildings turn raw tiles and input goods into trade goods on your estate. Unlock them at the right town level with research points, place and connect them to the warehouse, build, then run production. Workers carry output when storage is full.

From unlock to delivery

Six steps every production building follows on your estate.

  1. 1Unlock

    Each building needs the matching town level (same rule as goods on the database cards) plus research points in the tech tree before you can place it.

  2. 2Place on map

    Pick a valid spot on your estate grid. Building size and terrain must fit. Use the layout builder to plan ahead.

  3. 3Road to warehouse

    Connect the building to the harbour warehouse with roads. Construction cannot start until the route is complete.

  4. 4Construct

    Assign a worker to build. When the timer finishes, the building is ready for production.

  5. 5Produce

    Assign a worker whose profession matches the building. Production begins once the worker is on the job.

  6. 6Deliver output

    When output storage is full, the worker walks goods along your roads. Where they go depends on building type (see How workers move goods below).

How workers move goods

Workers travel along roads to the nearest valid destination. Shorter chains and good placement mean less time carrying goods and more time producing.

Raw material buildings

The worker keeps gathering or producing until output storage is full, then delivers along roads to the warehouse, or directly to a downstream building that needs that good if it is closer than the warehouse.

Craft and processing buildings

If another worker is already bringing inputs, this worker stays put and focuses on output. If not, they fetch inputs themselves from the nearest raw-material building with stock, or from the warehouse if that is closer. Once output storage is full, they carry finished goods the same way: to the warehouse, or directly to a downstream building that needs them if it is closer than the warehouse.

Idle and rest bonus

Workers idle when they cannot work: no inputs available, a full warehouse, or nowhere to deliver. While idle, rest bonus accumulates for up to 24 hours. When work resumes, production runs 50% faster until that stored bonus is used up. For example, if the warehouse is full the worker waits; once you move goods out and they can deliver again, they start working with the rest bonus active.

Plan road length and building order in the layout builder. For profession match and traits, see the workers guide.

Worker production speed

Profession match sets how fast a worker produces while at the building. The percentages below apply to production speed, not to walking or carrying.

Wrong profession

100%

Base speed. Worker can still operate the building

Pioneer or same profession

150%

Correct profession line, but not the building specialist and not yet trained to 200%

Specialist or trained to 200%

200%

Building specialist, pioneer trained at the Academy, or same-profession worker trained at the library (Town Library)

Specialist trained in Academy

250%

Building specialist after Academy training

Beyond profession match

The tiers above set your baseline. Plan and use manifest cards wisely. Combine them with well-trained workers and every other active bonus when timing matters.

  • Manifest cardsTimed production boosts across many card types and tier combinations
  • Auction personalities24-hour guild buffs from historical personality auctions
  • Mayor bonus10% or 20% on selected goods for 48 hours
  • Rest bonus+50% output while stored idle time is spent working

Line up manifests with your best workers and every bonus that is active. Use the production calculator to model the combined stack.

Academy

Train a worker for +50% on their current tier. A pioneer can reach 200%; a building specialist can reach 250%.

Town Library

Pair two workers from the same profession but different specializations to gain skill: 150% becomes 200%. Matching the same specialization only earns research points.

Library pairing

Hemp planter + orange planter → skill progress toward 200%. Hemp planter + lumberjack forester → research points only.

Use the production calculator for output estimates.

Gold upgrades

Spend gold on each building to raise production speed, add worker slots, extend building radius, increase output capacity, and reduce input goods ratios.

  • Production level

    100% → 300%

    Twenty levels at +10% each. Level 1 is base speed; level 20 is triple output.

  • Worker slots

    1 → 2 → 3

    More slots let more workers operate the same building at once.

  • Building radius

    Up to 6 tiles

    Plantations, tree harvesters, and farms let workers assign gather tiles farther from the building.

  • Output capacity

    1 → 8 batches

    How much a worker holds before walking to the warehouse. Tech tree unlocks raise the cap; this building upgrade sets the batch size per trip.

  • Input goods

    Max → min

    Craft buildings need more inputs at low upgrade level and less at max. Building cards show max → min per input good.
