EVALUATION OF CRITICAL SUCCESS FACTORS FOR SUSTAINABLE HOUSING DELIVERY IN LAGOS STATE, NIGERIA

Abstract

Housing is a global phenomenon and a fundamental ingredient of human societies. It is not just a roof over one’s head, but also a crucial element in achieving integrated physical and economic development, natural disaster mitigation, employment generation, wealth creation and sustainable development. Despite the varied housing policies guiding the Nigerian housing provision, its delivery is yet to level up with the global acceptable sustainability requirements. Previous studies revealed that developing countries are yet to unravel and embrace the tenets of sustainable housing delivery. This study evaluated the Critical Success Factors (CSFs) for sustainable housing delivery in Lagos, Nigeria. The study adopted general survey and AHP survey for the analysis. The target population for the study are the Registered Real Estate Developers who are practicing in Lagos. Data were collected with the aid of structured questionnaire administered on the 91 Real Estate Developers in Lagos. The data collected were analyzed using both descriptive /inferential statistics (Weighted mean and factor analysis) and Multi Criteria decision technique (Analytic Hierarchy Process Survey). The findings from the study showed that the developers are very much aware of the economic dimension of sustainable housing delivery while their awareness level on environmental and social dimension is quite low. The ranking and normalisation analysis showed that there are 18 critical barriers to sustainable housing out of which deficiency in government motivations for sustainable housing, non-existence of sustainability enforcement and absence of information on sustainable building technologies database were the topmost three that were critical. The factor analysis showed that the underlying barriers groupings of the 18 critical barriersare: Technology and cost barrier, knowledge and awareness barrier, policy implementation barrier, client barrier and economic barrier. The mean ranking showed that significant benefits inherent in sustainable housing delivery in the study area include quality of lives improvement ranked 1st (mean =4.25), setting standard for future design ranked 2nd (mean=4.11), and reduction in cost of maintenance ranked 3rd (mean =3.99) . The result of the factor analysis of the benefits showed the underlying grouping of the 22 benefits which are satisfaction related benefits, housing promotion related benefits, cost minimization related benefits, economical promotion and environmental development .Findings from the AHP survey revealed that government funding towards sustainable housing, access to low-interest housing loan, mandating affordable housing development, ensuring community participation during housing delivery, the involvement of housing stakeholders, ensuring the security of life and properties, use of sustainable materials, adaptable housing design and befitting land use are the significant CSFs required for enhancing sustainable housing delivery. Based on the findings of AHP, a model of the significant CSFs was developed to promote sustainable housing delivery in Lagos, Nigeria. Based on the findings of the study, a framework was developed to promote balanced built environment which was validated by industrial practitioners and built environment academic staff to confirm its credibility and reliability. The study concluded that the identified CSFs are very crucial for sustainability housing delivery attainment in the built environment. Recommendations are that the stakeholders involved in housing provisions should put in place effort to ensure that the constraints to sustainable housing delivery are averted through the integration of the CSFs for sustainable housing delivery, adoption of the developed model and framework as they are critical in achieving a sustainable housing and a balanced built environment.
