Buildings

Buildings are bought in the Shop. Pick one, place it on a free spot, and pay its price. Then a free Builder builds it, which takes some time. You can finish it now with Gems. If you cancel, you get half the price back.

Upgrading works the same way: it costs Cash, Oil or Uranium, needs a free Builder and takes time. Walls and decorations are built at once. Your Headquarters level decides how many of each building you can have and how high you can upgrade them.
