Anno 1404 Wiki
Can be enlarged by building Storehouses and by upgrading Market buildings.

The Storage capacity of your islands allows you to keep a buffer of Goods, which is helpful for construction, when waiting for a ship to arrive on a trading route, or to give more time to expand production when the demand for Goods increases. Reaching maximum Storage capacity for a Good is almost always sub-optimal, since it stalls production while the maintenance of the buildings remains the same. In this case it might be good to increase Storage capacity of your island.

The game offers two ways to increase Storage capacity. The first is by building and upgrading Trade buildings (Warehouses and Market buildings). This generally offers a gradual increase of Storage capacity appropriate for each stage of the game. When this storage becomes too limited, however, more dedicated Storage buildings can be built.

Without Items:

  • Market buildings are very cost-inefficient when used purely to expand storage.
  • Small and Large storehouses perform similarly. They have a low space efficiency, however, making them unsuitable for reaching maximum Storage capacity. 2 Large storehouses take as much space as 3 Small ones.
  • Historic warehouses are costly and slow to build, but provide the most well-balanced storage increase.

With Items:

  • +10 20xtext-bottom or less: Small storehouses are superior to large ones as they have less maintenance per ton (0.60 gold/ton vs. 0.75 gold/ton), but historic warehouses remain cheapest in the long run (0.5 gold/ton). (Capacity increasing items have no effect on Historic warehouses.)
  • +15 20xtext-bottom or more: Small storehouses are the best choice as they have equal or lower maintenance per ton of all storage buildings and are the cheapest to build. With a +15 increase item, a small storehouse costs 0.5 gold/ton versus 0.67 gold/ton for a large storehouse and 0.5 gold/ton for Historic warehouses. Two +10 items would make Small storehouses 0.43 gold/ton and large storehouses 0.60 per ton.

Still, you may want to reserve your Item slots for other items, making Historic warehouses your best choice. A good productivity-increasing item can make you far more gold per minute than a small-storehouse approach can save you.

Tip: The maximum Storage capacity for an island is Storage capacity 999, which usually means building 3 Historic warehouses (Storage capacity 900), assuming 100 tons of additional storage from a Warehouse (40-60 tons) and around 8 Market buildings.

The Provision house is a curiosity: With the Venice add-on installed, it provides 10 tons of storage space. It also doesn't have any maintenance costs while not producing provisions (its maintenance is 15 gold/minute for the 24 seconds it takes to make a provision package). This makes it the cheapest possible storage space relative to maintenance, but it costs so much to build that probably few use it for storage alone.
