Unique Factories were added by the Industries expansion DLC, and being unique buildings, only one of each may be built in a city. While unique, these factories are not a part of the Unique Buildings category.
All Unique Factories produce Luxury Goods from Special Goods which cannot be imported – you must use Processing Buildings to manufacture them within your city.
Special goods are made by the Industry Area processing buildings.
There is one Unique Factory for each industry type that can be built without having any other industry type. All other Unique Factories require at least two industries to function.
*The Soft Paper Factory has an 8x16 cutout on the road side of the building. It only requires 16 cells by the road.
Special Goods Requirements
In addition to the various Special Goods required, note that some of the Unique Factories also use "Crops", a Raw Resource.
Production Rate and Economics
The production rate of every unique factory is affected by a slider that goes from 50% to 150%. The production rate is then multiplied by the Industry Budget based on the equation of budget efficiency. The upkeep of the unique factories are also affected by the production slider and Industry Budget but it is not affected by the budget efficiency.
Using the Furniture Factory as an example at 150% production rate and 150% industry budget:
1,000 units / 1 ton of Luxury Goods can be exported or sold to commercial shops for ₡1,000. This means that running the industry budget at 150% can greatly increase your profits if most of your income comes from Unique Factories as the income gained from selling the goods greatly exceed the increase in upkeep. If you have the Campus DLC, constructing a School of Science in a University Campus Area will further increase the amount of money gained from selling Luxury Goods by a large amount.
The Shipyard has a unique mechanic among the Unique Factories. It only creates cruise ships that logically cannot be sold to commercial shops as it is too big to fit in one and is too expensive for the average person to buy. Instead; when the Luxury Goods storage of the shipyard becomes full, the cruise ship will immediately be exported without needing trucks or vans to ship it.
