Building

 is a mechanic in The Three Brothers DLC which takes place in the city of New Sirocco. Building requires starting the A Fallen City quest. As you progress through the Sirocco quest line you will unlock more advanced buildings, and you will be permitted to place more buildings as well.

Blueprints
Blueprints can be purchased for a few silver from Josef Dumas, though the player will only be able to purchase Blueprints which they have unlocked so far.

To construct Buildings, use the Blueprint to start deploying it. Find stable ground and notice the deployed Building indicator turn blue, this means you can place the Building here.

When a building is undergoing construction, a Ledger will appear at the front describing the state and requirements for building to commence. The building process usually takes multiple phases to fully complete, and players must restart the building process through the Ledger for each phase.

To use an Upgrade, it is the same process as deploying a Building, except you must deploy it on top of an already constructed Building which corresponds to the Upgrade.

Resources
By speaking to Dorion Dumas, players can manage their, and  supplies by providing  (through Silver or Gold Ingots). As the city becomes more advanced, many buildings will passively generate resources for the player as well.


 * are equal in value to silver, and players are also able to exchange a Gold Ingot for 100 funds as well. Funds are used both for construction and for upkeep costs.
 * and are only required for construction and upgrades, there are no buildings which require them as upkeep costs.
 * is only used for upkeep costs.

You only need Resources for as long as you are still building your city, after that there is no downside to ignoring them all. You are not able to withdraw funds or any other resource from the coffers.

General Tips

 * Do not rush into building too quickly, you are limited both in Resources and by a cap on each building type. Build only what you need to and can afford to.
 * It is recommended to build the City Hall near the entrance to the city, as the important NPCs will be found here.
 * Put low priority buildings (Houses and Resource Collection) somewhere out of the way, not near the entrance. You don't need to visit these once they are constructed.

List of Buildings
In addition to the potential Buildings players can construct, the city comes with a Stockpile.

Blueprints can be purchased from Josef Dumas.

Housing
Each house adds +1 Housing to your City, allowing you to construct more advanced Buildings.

Players can build up to 5 Houses, however maximum Housing value can exceed 5 as certain Buildings grant bonus Housing.

Resource Collection
Resource Collection buildings will passively gather Stone, Timber and Food for your City.

Players can build 1 of each Resource Collection building.

Specialized
Players can choose up to 6 Specialized buildings to place in their City (or more realistically, a City Hall and 5 of the other 8 possible buildings).

Specialized Upgrades
For specialized buildings, you can only pick one of the two available upgrades. Some upgrades require a certain faction.
