For us who worked on these projects from 1977 onward, the main objective was to demonstrate that formal housing projects could be affordable to low income households (our target was between the 20th and 35 percentile) if urban minimum regulatory standards were revised. Our hope was that minimum housing standards would be revised after it was shown that they did not result in slums. Everybody agreed at the time that the end result was desirable but the minimum housing standards were never revised, therefore preventing private developers to build sites and service projects. Only the government was allowed to build under these standards. The failure was not the projects themselves, but the inability to obtain a revision of the absurd minimum housing standards.
