About $920–$1,955 per m² ($85–$182 per ft²) for this building type at a standard finish. Per-m² rates rise with storey height (frame, cores and cranage) and with specification, and fall on simple single-storey plans.

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. Ireland sits at index 115 against the United States at 100, which is why the figures above differ from what you'd see quoted for the same building elsewhere.
