Building Expansion Mod

This mod is not compatible with most other mods because it modifies many state traits to add mines, which conflict with a lot of other mods.

No conflicts (verified):

• Morgenröte – Dawn of Flavor

Construction is one of the most important aspects of Victoria 3, but the Construction Sector lacks depth, offering only wood, iron, and steel as building materials. Additionally, there is no gradual transition between construction methods.

Between 1836 and 1936, the use of aggregate materials such as stone, gravel, clay, and limestone became widespread, yet the base game does not include them. This mod introduces these materials, creating a smoother technological progression and new ways to advance construction.

• Adds depth without disrupting the core mechanics of the game.
• Enhances construction progression by adding intermediate materials.
• Improves construction efficiency by reducing reliance on wood, iron, and steel.
• Creates new jobs with Aggregate Mines and Construction Factories.

This mod does not alter the core gameplay but introduces new mechanics specific to the construction sector.

Aggregate mines have been placed in historically plausible locations. Balancing may be required, and feedback is welcome.

• Aggregate Mine – A processing plant that crushes stone, gravel, clay, and limestone into aggregates used for construction.
• (NOT ADDED) Construction Materials Factory – Processes raw aggregate into refined building materials for more advanced construction.

• Aggregate – Raw materials such as stone, gravel, clay, and limestone used in the Construction Sector and Construction Materials Factory.
• (NOT ADDED) Building Materials – Refined materials that improve construction efficiency and support infrastructure development.

• Building Material Utilization – A new category of construction production methods.
• 27 new production methods added for Aggregate Mines and Construction Factories.

• Aggregate mines have been strategically placed across the map.
• Some Aggregate Mine locations have been given a 25% throughput bonus through updated state traits.

• Rotary Kiln Processing – Unlocks improved production of cement, lime, and aggregates.
• Industrial Construction Methods – Increases efficiency by integrating new material processing into construction.

This mod is designed to improve realism and gameplay while keeping the core experience of Victoria 3 intact, challenging, and fun.
