Project Abstract

Abstract
The cost of building materials plays a crucial role in housing development projects in Nigeria. This research project aims to investigate the effect of building material costs on housing development in the Nigerian context. The study will focus on various aspects such as the impact of fluctuating material prices on project budgets, the relationship between material costs and housing affordability, and the strategies employed by developers to mitigate the effects of rising material prices. In Nigeria, the construction industry faces challenges related to the availability and affordability of building materials. Fluctuations in material prices can significantly impact the overall cost of housing projects, leading to delays, budget overruns, and reduced affordability for potential homeowners. Understanding the dynamics of building material costs and their implications for housing development is essential for policymakers, developers, and other stakeholders in the construction sector. The research will utilize a mixed-methods approach, combining quantitative analysis of material cost trends with qualitative data from interviews and surveys with developers, contractors, and policymakers. By examining historical data on material prices and analyzing current market trends, the study aims to identify key factors driving cost fluctuations and their impact on housing development projects. The findings of this research are expected to provide valuable insights into the challenges posed by building material costs in the Nigerian housing sector. By highlighting the implications of material price fluctuations on project feasibility, affordability, and sustainability, the study will contribute to the development of strategies to address these challenges effectively. Recommendations based on the research findings can inform policy decisions, project planning, and investment strategies in the construction industry. Ultimately, this research project seeks to enhance understanding of the dynamics between building material costs and housing development in Nigeria. By shedding light on the factors influencing material prices and their effects on project outcomes, the study aims to support the development of a more sustainable and resilient housing sector. Addressing the challenges posed by material costs is essential for ensuring the continued growth and affordability of housing in Nigeria, ultimately benefiting both developers and prospective homeowners.

Project Overview

INTRODUCTION

1.1   BACKGROUND TO THE STUDY

Researchers in building sector have indicated that between 50 to 60 per cent of the total construction input goes into building materials. As a result, there is an urgent need to address the high cost of these products which is said to have slowed down the growth of the building and construction sector in Nigeria.Building materials constitute the largest single input in housing construction. While Adedeji(2010) observed that about sixty (60) per cent of the total housing expenditure goes for the purchase of building materials, Arayela(2005) averred that the cost of building materials constitute about 65 percent of the construction cost.

Ogunsemi (2010) opined that building materials formthe main factors that restricts the supply of housing andascertained that they account for between 50-60 percentof the cost of buildings. Thus, Adedeji (2002) rightly observed that one main barrier to the realization of effective housing in Nigeria as revealed in successive government efforts has been the cost of housing in the country. He argued that in the early periods, shelter in Nigeria was easily affordable as building materials were sourced from the immediate environment at affordable costs. Technology also was readily available withcommensurate simple techniques. But contact with the outside world through interregional and international training of professionals in foreign countries as occasioned by colonization, brought changes to tastes and hence outlook to house forms. These changes rendered the undeveloped local building materials inadequate while there was an increased demand for exotic ones. Accordingly, Arayela (2002) posited that the modern building industry lays much emphasis on sophisticated building materials and techniques that are expensive and energy consuming. Though, housing delivery efforts have evidently been inhibited by prohibitive costs of building materials,this problem cannot be reasonably and reliably overcome by merely resorting to the use of locally available materials without due considerations to the applicable initiative, the cost of processing and sustainability of the local materials. One of the most important components of asustainable building is the material efficiency. Correct selection of building materials can be performed by taking into account their complete life span and by choosing products with the minimal environmental impacts. For instance, González and Navarro (2006) estimated that the selection of building materials with low environmental impacts can reduce carbon dioxide (CO2) emissions by up to 30%. The use of renewable and recycled sources is widely encouraged as the life-cycle of a building and its elements can be closed (Chwieduk, 2003). The major factor that greatly affectthe selection of building materials are their costs and social requirements such as thermal comfort, good mechanical properties (strength and durability), aesthetic characteristics and an ability to construct quickly. Ideally, the combination of all environmental, economic and social factors can give a clear description of a material, and thus helps in a decision making process regarding the cost of the materials suitable for buildings (Abeysundara, et, al.,2009) . Nigerians would continue to pay more for accommodation in major cities until the cost of building materials is subsidized through probably through tax reduction. The instability in the price of building materials was posited as a direct result of high taxes which in turn impacts on the cost of accommodation in major cities across the country.According to Arayela (2002), many completed housing estates had remained unoccupied because of the high rental and sale prices attached to them as against the meager income of the average Nigerian workers. He also added that if government can revitalise our industrial base, the cost of building materials will come down and many more people would be able to build houses.He therefore  urged the Federal Government to provide tax relief for local manufacturers and importers of building materials in order to reduce the high cost of accommodation in major cities.
