Buildings

Housing Buildings
Produce coins and add to the population. Housing provides a steady source of coins. You can collect coins from housing when the timer reaches zero. After collecting, the timer will reset. Housing will provide dwellings for your residents, thus increasing the population. If the population exceeds the limit, you won't be able to build housing anymore.
