Fixed Building Types
These buildings come with the map and cannot be bought.
Bank
The bank is the Building that saves money for you while you have the game closed. Upgrading it increases the time allowed for it to save money. The game upgrade Day Trading will also increase this amount.
Town Hall
The Building itself holds no function other than being a shortcut you can tap to get to the upgrade screen. It also functions as the icon of the game.
Garage
The garage is where you unlock cars. It also has the most amount of vehicle types per vehicle division.
Airport
This is where planes are purchased. Mid game, the second best earner of the vehicle types. But the tier 8 upgrade where planes get a large boost per active unit will make it the highest earning one.
Docks
Where boats are purchased. Boats are the largest earning active reward vehicle. Especially in bux where normal rewards give 10 and large rewards give a whopping 100 bux.
