In How Buildings Learn: What happens after they're built, Stewart Brand states that “The flow of money through a building acts to organize the building.” [1] In Sub-Saharan Africa, low income households face challenges with this flow of money due to lack of access to the type of mortgage finance that is the norm for middle and upper class households in other parts of the world. Money for home construction tends to be accessed in relatively small quantities compared to the task at hand, often over a period that can be measured in years. The result is a home that is built incrementally. Incremental construction becomes an exercise in prioritizing the flow of money across what Brand calls the Six S’s: Site, Structure, Skin, Services, Space Plan and Stuff. Services and Space Plan naturally fall after site and structure as priorities, but often surprisingly fall after skin as well.
Services typically include water, electricity or gas connections to a building. Because of climate considerations and the relative cost of various building materials, the most common construction material in Africa is some kind of brick or block. [2] This means that the services must be added through and on top of a block wall. Cladding over the block is extremely uncommon in low income households, with a plaster and paint being the most common interior skin, if there is one at all. Conduits are frequently placed into channels carved into the wall and covered with plaster with the exception of the socket outlets. There is not, however, a significant taboo against having visible conduits in low income households. It is not uncommon to add them directly over the skin instead of the skin being added after the services to hide them.
Housing Microfinance loans for services can link to water and sanitation efforts in upgrading informal settlements. Clients may use a housing microfinance loan to connect to potable water, sewage or a septic tank. The housing microfinance program in which I currently work is in an urban setting and electricity connections are a popular loan use. Loans for electricity connections tend to be taken by households that have reached some level of satisfaction with the structure and skin of their home. These loans are sometimes associated with home-based businesses that may use a refrigerator, freezer, electric sewing machine or other gadget. It is interesting that the “stuff” that uses the electricity is often acquired before the service is connected to the house, having been used in rented accommodation, kept in another person’s house, or used with car batteries that are periodically sent out for charging.
The Space Plan includes non-load bearing walls, ceilings and doors and windows. Because it is very common for low income households in Africa to move into a house before it has all (or sometimes even any) of its doors and windows, these become a common use for housing microfinance loans. In our MAKAZI BORA home improvement loan program in Dar es Salaam, Tanzania, doors and windows may be the most common house component sought, sometimes on their own but often as part of applications for roofing, or other improvements. Some loans have been used for improving existing windows with screens (to keep out mosquitoes) or bars (to keep out other unwanted visitors). Clients with very low incomes have purchased and installed second-hand windows and doors to shut their houses, while clients with slightly higher incomes have used the opportunity of a housing microfinance loan to purchase doors and windows of higher quality and durability.
Ceilings have also been a popular loan use. Like electricity connections, these tend to be for clients who have basically satisfied the rest of their housing priorities as they have worked through their incremental building process. Loans for ceilings are sometimes for relatively wealthier clients, but sometimes simply for clients who are further along in their process as they continue to build and organize their houses according to their own image of what their home should be.
Housing microfinance can be made flexible enough to assist people at all stages of their housing process as they acquire, add, or modify site, structure, skin, services and space. Access to housing finance increases the velocity at which a low income household is able to develop and organize its home. The more flexible a housing microfinance product is, the more utilitarian value it will have for dwellers in their housing process and the greater the potential demand for the product. Although this is a hypothesis to be explored more in-depth at another time, the very awareness of the ability to access affordable housing finance may assist a household in organizing and planning its journey through the 6 S’s.
