With the ever-rising population index around the world, the need to provide suitable
accommodation to meet this demand can’t be over-emphasized. Hence, the need to
explore the utilization of locally available building materials, which can accommodate all
economic classes, because of its potentiality of being cheap. In developing countries, this
can help in mitigating the housing deficit. It as well as a promise of simpler building
techniques, which will invariably encourage self-built houses, another advantage to
mitigating the housing deficit.

PROBLEMS
Housing deficit is a major
problem plaguing Nigeria,
amongst other nations in the
world. The need to find a
solution to this problem
becomes imperative, because
the life dependence of people
largely connected to it.

WHY IBADAN???
Proximity to Lagos
The new railway Line
Availability of resource
Availability of Land.

AFFORDABLE HOUSING
Affordability in housing is mostly measured by the cost of the
available houses in relation to the income rate of the potential
subscriber. The margin between the income of the larger percent of
the citizenry and housing cost is so high that the low-income earners
are eliminated from the market by default. The increasingly high cost
of building materials, the inflation rate of the economy, ludicrous
profit demanded by developers and contractors, amongst many
others, are major contributors to the unaffordability of houses in
Nigeria, Bello (2008).

LATERITE CLAY
They are formed from weathered rocks, from the effect
of rainfall and sunshine, majorly found in tropical
regions. Iron, Aluminum, Manganese, and Titanium
oxides are the major constituents of laterite. These
types of bricks are formed from the composition of
lateritic soil clay and clay-sand mixtures with an
aggregate of 60% sand (weight) and 40%clay (weight).
The process of water curing is used in drying it.
11

Dry stack masonry reduces
the overall cost of
construction by about 27%
less. (Ngowu, 2005). This is a
process where the bricks are
stacked without the use of a
binder (mortar). It is one of
the recent forms of laying
the bricks, from about two
decades ago. The reach of its
application is well over 40
countries around the world,
because of its effectiveness;
economically cheaper, faster
construction period, and
engagement of lower-skilled
labor, amongst others.

DESIGN PROPOSAL
The introduction of the railway system between Lagos and Ibadan is a
positive change that promises a leap in development. The major
manifesto of this scheme is, ‘’work in Lagos while living in Ibadan’’.
Lagos being the most populated city in Nigeria, according to the world
population review, 2020 needs to be decongested. The population is
straining the available infrastructure available in the state. The
introduction of this scheme by the federal government seems like a
plausible solution to overpopulation. Ibadan has a city that will
benefit from this migration economically and socially, bringing a
change in its demography and the possible attraction of investors.
14

SOLUTION
According to research, it is observed that the housing deficit in
Nigeria is mostly attributed to affordability. In the world bank
publication of 2020, it was stated 79.3% of the citizenry occupying
the multidimensional poverty headcount ratio. The need to start
building infrastructures that are pro-poor can’t be overemphasized.
The introduction of vernacular modernism, which explores the use of
traditional natural materials becomes a feasible option.
Clay (laterite) being a popular sourced material in Ibadan, can be
harvested to provide cheaper, sustainable, affordable, and ecofriendly
housing for the middle and lower citizenry.
Their sizes vary, usually the discretion of the manufacturers or the intended
use. Mostly it is always in 40x50x100mm.

‣ Revision of land tenure policies
‣ Recognition and support from government
‣ Partnership
‣ Accessibility to mortgage
‣ Provision of infrastructures

CONCLUSION
It is rather apparent that sustainability and
affordable housing goes hand in hand. Solving the
immediate needs of the housing deficit doesn’t stop
there, rather it's paying attention to the need of the
future without impeding. It is of great importance
to pay attention to factors such as stakeholders,
design, social needs, and the environment when
discussing affordable housing because they
determine the success and sustainability of the
project.
Although sustainable housing doesn’t necessarily
mean it is affordable, one can design affordable
housing meeting the sustainable tiers in respect to
the social, economic, political, and environmental
needs of man.
