Kwaku Gima has spent almost fifteen years building his family a house, and it’s still not finished. The floor hasn’t been plastered smooth and the kitchen cabinets are yet to be fitted. Last year the 47 year old high school teacher in Ghana got a mortgage from a co-operative society to build a home he expects to be complete within nine months.

The difference? Gima built his first house the traditional African way: One stage at a time, over many years whenever he could spare something from his paycheck.
