ABSTRACT
This study was intended to examine the effect
of building material cost on housing development in Nigeria.
This study was guided by the following objectives; To
determine the factors responsible for high cost of building materials in
Nigeria, To proffer solutions that will reduce the cost of building material to
ensure adequate housing development in Nigeria.
The study employed the survey and explanatory
design; questionnaires and interview in addition to library research were
applied in order to collect data. Primary data sources were used and data was
analyzed using the correlation statistical tool at 5% level of significance
which was presented in frequency tables and percentage. The respondents under
the study were 50 civil
engineers and quantity surveyors in Imo State. The study
findings revealed that The cost of building materials is on
the high side. The cost of building materials has everything to do housing
development in Nigeria. Housing development can influence the economy of
Nigeria.
The results of this study will sensitize the
policy makers and the government on the need to make and implement policies
that will reduce the cost of building materials in Nigeria thereby encouraging
massive housing development all over the country.

CHAPTER ONE
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.
