If a building has spots available to mint you can do so by opening the mint page from the property menu. The current cost
of minting a unit is
0.05 ETH. The availability of minting is determined by the city progression factor and the
inherent height of the building. You can view the Attributes section of a property to learn more about available spaces and
Minting is currently exclusive to Building owners as all current available placements are privately owned.
