People improve their own houses after being given assurances that they will not be evicted - and are sometimes given legal ownership of the land. Tend to improve house in a piecemeal way, improving mud walls to brick, adding rooms and floors. Eventually bus operators and rubbish collectors will start services and the area changes from a poor, illegal settlement to a legal medium quality area.
