The gradual densification of settlements, although providing for many more inhabitants, requires time, a luxury not available when confronted with areas such as Diepsloot. Simultaneously, the existing settlement infrastructure and social amenities are often overburdened by the increased occupation density.

Back-yard dwellings are gradually being recognised as having the potential to impact positively on the housing backlog not only due to minimal cost to the state, but also in that they cater for non-qualifiers. The row-house type, promoted as the alternative to the RDP, starts out with higher initial densities, but has limited growth potential over time since tenants need to pass through the main house to access their accommodation. Units with passages on one side or access lanes at the back of stands may alleviate this to a degree.

Whilst BNG principles have been developed to render houses ‘safe’ as collateral for bank loans current densities are not particularly efficient in the use of land and infrastructure. The banks and the state furthermore frown upon self-constructed additions in their prejudice and lazy thinking towards the informal city, effectively blocking whatever potential the may reside here.
