THE MINIMUM SHELTER APPROACH CAN PRODUCE HOUSING WHICH THE POOR CAN AFFORD. FCH International, Inc. 1972. A subsidiary of the Foundation for Cooperative Housing (now called the CHF – Cooperative Housing Foundation).
An early report prepared for USAID, which proposes a "minimum shelter" form of housing. “This can be .. provided in many ways. One is a "shell” house consisting of only a roof and a floor; another is a "core" house, which is an enclosed structure that includes basic fixtures. It can be completed and expanded by the occupant himself as his income permits. Another alternative for a very poor family isthe "site and service” approach. Here the bare plot and minimum services, such as water and waste disposal, are provided and the resident develops the type of shelter he can afford himself.
There are two elements that set the "minimum shelter” model apart from other models. It provides a unit that is designated to match the ability to pay. In the traditional approach to housing planners have designed a house and then estimated how many people could afford it. The minimum shelter approach works differently. Here, an architect begins with the fact that a family perhaps could afford six to ten dollars a month for shelter; he is then faced with designing a housing solution that will be possible within that monthly payment constraint.
The second way that this model differs from the traditional is that it provides a range of shelter solutions that can be produced by the occupant himself, , with a minimum of outside help, once the framework has been established. Thus, occupants can build up an equity of independence and freedom from constant government assistance. The minimum shelter approach has already been tested with [US]AID and FCH help in Panama and experience shows that tenants do not let their plots remain barren for very long. They make continual improvements on their dwelling units,bringing them up to a standard level on their own, over a period of time.”
EXTENDING THEMSELVES. User-initiated transformations of government-built housing in developing countries. Graham Tripple. Liverpool University Press. 2000.
Mr. Tribble uses the term ‘transformations’ for the modification and expansion of the housing, and the people ‘transformers’. He surveys in depth government housing projects in four countries: Mirpur, Dhaka; Medinet Nasr in Cairo and Workers’ City in Helwan, Egypt; Asawasi and Suntresco, Kumasi, Ghana; and Mbare and Highfield in Harare, Zimbabwe.

TIME BUILDS! (El Tiempo Construye!). EquipoArquitectura (Fernando Garcia-Huidobro, Diego Torres Torriti, Nicolás Tugas). Editorial Gustavo Gili, 2008. One of the few detailed studies of the Experimental Housing Project (PREVI) in Lima, Peru, which was a result of the 1967 international competition for low income housing sponsored by UN Development Program and the Banco de la Vivienda of Peru. The top architects of that time – and many are still prominent today – designed proposals for low-density, progressive housing neighborhoods in a context of limited resources and urgent urbanization. Aldo van Eyck, Charles Correa, James Stirling, Christopher Alexander, Atelier 5, Fumihiko Maki, Candilis, Josic and Woods, among others participated. Selected units were built in a prototype neighborhood and this book revisits the results after 40 years.
