Why do build costs vary so much between countries?
+
Three things dominate: labour cost, how much of the material basket is imported, and the code requirements the building must satisfy. Bulgaria sits at index 48 against the United States at 100, which is why the figures above differ from what you'd see quoted for the same building elsewhere.
