dc.description.abstractSustainable housing delivery is a huge challenge in developing countries in view of the rapid urbanization, which has led to tremendous increase in population. Onsite and offsite construction methods have been identified as means of procuring houses sustainably. The aim of this study is to assess various onsite and offsite construction methods for appropriate housing delivery. The objectives of the study are to assess the adoption of onsite and offsite construction methods; to examine factors that influence the choice of construction methods in construction organizations; and to determine the sustainability of onsite and offsite methods. The research design used was survey design, and questionnaires were used to collect data. The population of the study include Architects, Builders, Civil Engineers and Quantity Surveyors who are duly registered with their various professional bodies. The sampling frame for the study was the 56 registered construction organizations with the Lagos State Ministry of Housing. Frequency, percentage and mean were used to analyze the data. The study found out that there are eight onsite and offsite construction methods used for housing delivery out of which block/brick mortar is the most adopted method. High profitability is the most influencing factor for choice of any construction methods. It is concluded that although there are several methods for procuring houses, cost and not necessarily sustainability, is still the major determinant of adopted methods, which implies that block/brick method enhances profit margin. It is recommended that constructional professionals should increase the usage of other construction methods that are more sustainable, in lieu of block/brick method. This can be achieved through training by construction organizations and institutions. Professionals should also endeavor not to be too profit-inclined in the selection of their construction methods. This can be realized by Government encouraging professionals who engages sustainable methods, through providing fiscal incentives in the form of tax reliefs in acquisition of building permits and certificate for Completion and Fitness for Habitation.
