In your city
The Office Tower unlocks in the Modern Age. With its workers in place it makes 270 gold per minute. It employs 14 workers.
Upgrades
Once it is finished, tap it and choose Upgrade to raise it a level, up to level 3. You pay up front; the work then takes a while, shown by the same bar as construction, and the Office Tower keeps working at its old level meanwhile. From level 2 it wears its level on an enamel house-number plate. How upgrades work.
