Multiple Floors System for Retail Stores
This DLC adds a multiple floors system for retail stores. Adding a floor increases the number of products a store can sell, expanding its retail capacity.
How To Enable The Multiple Floors SystemAdding a floor
Find the New Floor icon
It sits underneath the 3×3 layout area.

Confirm the cost
Clicking [New Floor] shows what the floor will cost before you commit.

Use the new space
The floor is added with its own fresh 3×3 grid for new functional units. A store can be expanded to a maximum of 3 floors.
Operating overhead rises in direct proportion to the number of floors. Only expand where consumer demand for your products justifies it.
