The highly dense and rapid pace of construction in the Basti has led to inappropriate construction methods and poor light, ventilation and sanitation within homes. Several homes in the Basti have been built using poor construction techniques and material.

Following several queries on repair and retrofitting, the housing improvement programme focused on demonstrating methods for structural retrofitting and training of residents on good construction practices. Through a cost-sharing system with residents, AKTC intervened in several houses to carry out structural and design repairs as well as the retrofitting of homes. Residents were not only considered as beneficiaries of the scheme, they were also involved as active actors of the implementation phase. Not only they all participated financially, but they were also sometimes in charge of ensuring the completion of the works.
