This page prices an office building — three floors of open-plan office, RC frame, suspended ceilings, HVAC and lift allowance — at 2400 m² of gross floor area, then breaks the cost down element by element so you can see where the money actually goes. Costs are quoted in USD for comparability; the local currency in Benin is XOF (CFA), and a bill of quantities generated from your own drawings is priced in XOF using the DQE / DPGF standard.

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. Benin sits at index 26 against the United States at 100, which is why the figures above differ from what you'd see quoted for the same building elsewhere.
