In Hearts of Iron IV, building slots are essential for constructing factories, barracks, and other crucial buildings. However, not all players know how to unlock additional building slots or increase the existing ones. In this article, we'll explore various methods to acquire more building slots, including console cheats, national focuses, and industry techs.

Console Cheats

For those who want a quick fix, there are several console commands that can unlock extra building slots. However, please note that these commands are not officially supported by the game developers, and using them may affect gameplay balance or stability.

• regionwideindustrialintegration – This command unlocks an event that grants additional building slots for a region.
• unlockbuildingslot – This command unlocks an extra building slot in a specific state or region. However, the exact syntax for this command is not publicly known, and it may require some trial-and-error experimentation.

National Focuses

Hearts of Iron IV features various national focuses that can grant additional building slots. These focuses often come with other benefits, such as increased industrial output or improved military capabilities.

• Communal Property Act – This focus in the communist tree for the USA grants a decision to add one extra building slot.
• Industrial Effort II – This national focus increases building slots and factory construction in Italy.

Industry Techs

Researching industry techs is another way to increase building slots. Each level of industry tech grants 20% more building slots, up to a maximum of four additional slots.

• Region Wide Industrial Integration – This event, available through the regionwideindustrialintegration console command, increases building slots and industrial output for an entire region.

USA National Focus

For players who prefer a more official approach, the USA has a national focus called "Communal Property Act" in the communist tree. This focus grants a decision to add one extra building slot, providing a more balanced way to increase construction capabilities.

Other Methods

While not officially supported by console commands or national focuses, some players have discovered other methods to unlock additional building slots. These include:

• Building multiple factories in the same region to increase industrial output and subsequently unlock more building slots.
• Constructing regional infrastructure projects, such as railroads or canals, which can grant extra building slots.

Unlocking more building slots in Hearts of Iron IV requires a combination of strategic planning, research, and possibly some experimentation with console commands. Whether you prefer the official routes or unofficial methods, there are many ways to increase your construction capabilities and achieve your goals in this complex game.
