Real Estate Developers Insight on the Critical Barriers to Sustainable Housing Delivery

Abstract

Abstract Sustainability has been advocated in the housing sector in developing nations but its adoption is hampered with myriads of barriers. This study investigates the critical impediments to sustainable housing delivery. To achieve this, 18 commonly used barriers in existing literature were selected for investigation in this study. Structured questionnaires were administered to 91 housing developers within metropolitan Lagos, Nigeria and analyzed using both weighted mean and factor analysis. The ranking and normalization analysis showed that out of these investigated barriers, deficiency in government motivations for sustainable housing, non-existence of sustainability enforcement and the absence of information on the sustainable building technologies database were the topmost three critical challenges to sustainable housing delivery. The factor analysis also showed that the underlying factor groupings of the critical barriers can be classified into technology and cost, knowledge and awareness, policy implementation, client and economic related barriers. These research findings have added to the sustainable housing literature within the context of Nigeria. They also create a reliable blueprint which would assist all stakeholders in taking the sustainable approach to ameliorate these impediments, thus promoting sustainability attainment in housing delivery.
