| Building name | Effect | Cost | Building time turns | Description | City level required |
|---|---|---|---|---|---|
| Merchant's Wharf | Increase trade and enables 1 trade fleet | 1600 | 3 | When a port is first established, it is typically little more than a series of wharves to dock at. A Merchant’s Wharf however is built with loading and unloading cargo in mind. Equipped with a large yet simplistic crane and swing bar, its creators had the foresight to take the time out of a captains stay at the docks, allowing for a slight increase in trade throughput. | Minor City |
| Warehouse | Increase trade and enables 2 trade fleets | 3200 | 5 | As an ever-increasing amount of merchants seek to send wares across the water rather than on the back of a mule, the need for storage down at the docks also increases. The construction of a Warehouse ensures that goods can either be left ready to load, or unloaded without its land-carrier having to simply wait for the cargo ships to roll in. | Large City |
| Naval Drydock | Increase trade and enables 3 trade fleets | 6400 | 6 | Some coastal cities become true trade hubs, with several merchant fleets vying to engage the limited dock space themselves. For the governor of such a city, establishing Docklands is well worth the investment. Massive wooden wharves are built out into the bay, with smaller jetties coming off those to provide enough moorings to satisfy virtually all comers. | Huge City |
