When you spend 9million on a 15million naira project because of greed or low budget, luckily no life was lost, this should be an eye-opener to people whose houses are poorly constructed, at least, even a tenant should be worried about his or her safety - cracks on the wall, water leakage from the wall, straircase tilting, foundation sinking, pillar cracks, et cetera. Government should create a body to check these things out, also over-population in these residences also is a major factor, places like Lagos were cheap houses are gotten only in poor settlements, then a house that is supposed to take nothing less than 50 occupants is being occupied by 101 persons, how then will it not fail and collapse?
