Abstract

The housing deficit in Nigeria of 17million units is at alarming point with her continuous growing population of 2.64% annual average increase without adequate housing provision to meet the demands. The result of this is increase in congestion and slums rate i.e. Meanwhile, affordable housing provision through earth blocks would have reduce the limitation set by high cost of conventional sandcrete blocks. This paper presents the data on availability of the earth materials across the country, the significant cost reduction that can be achieved through the use of earth materials and its inflationary stability. Descriptive survey was employed for this study while comparative cost analysis was carried out to ascertain cost difference between earth block and convectional blocks. Results were presented in tables and charts. Findings revealed that earth materials are available in all the part of the country with largest deposit in south east and least in the south-south states. The cost analysis carried out on the convectional blocks and stabilized earth block affirmed that earth blocks are cheaper alternatives to convectional blocks with N98.03 cost difference, giving a 46% reduction in the total production cost. Finding revealed further that earth block has 60% economic stability. That is, has lesser fluctuation effect. Earth blocks is thus recommended for achieving sustainable and cost affordable housing delivery in Nigeria thereby solving deficiency in the system
