1)Soil Type
Two
plots of land side by side may have wide differing soil bearing
capacities. In fact, for the same building project, you will be
surprised that one requires raft foundation while the next plot requires
pile foundation. Cheap land doesn’t mean cheap construction. When
choosing your land, go along with an engineer to advice you on its
physical properties. Considering that raft foundation could cost
you 4 million naira while pile foundation could cost 14 million naira
for the same project, you may end up saving a whooping 10million naira
by making the right foundation.

2)Design Approach
If
you want to reduce the cost of construction, it starts with the design.
To spend less follow the 3S: Follow the Standards, keep it Simple, and
minimise the Space. Two people could build 5 bedroom duplexes with
similar layout with one party spending N28million while the other spends
N18million. How?
o Ensure rooms which require plumbing are kept close together to minimise the length of pipes you will need. o Use standard window sizes and simple roof structure as these sizes are readily available and much cheaper. o Use a simple building design layout be easy for contractor and labours to understand and work. o
Allow some rooms to share bathrooms. Keep the number of bathrooms to a
minimum as they are one of the most expensive floor areas in a house per
meter square. Even in expensive 2/3-bedroom suites in Dubai and
other service apartments, it is not uncommon to find the master bedroom
ensuite while all the other rooms including the living room share the
second bathroom and toilet which is so strategically located.

3)Think in Moderate Sizes
Focus
on what you need when building. Globally, the average size of homes are
shrinking fast so there is no need having rooms you will only make use
of once in a year.
In construction, more square footage equals
more money. For instance a 12 x12 feet room(3.6 x 3.6 meters) has total
area of 12.96m2 while 10 x 10 feet (3 x 3 meters) has 9m2. If your house
consisted of 10 of such rooms that literally means for every 10 million
naira you spend on a room of 12 x12 feet room (3.6 x 3.6 meters), you
could have spent just 7.5 million naira if the room size was 10 x10 feet
room(3 x 3 meters).
Why is this so? because that extra 3.96m2
(12.96m2 - 9m2) that comes with the 12 x12 feet room(3.6 x 3.6 meters)
means 25% extra on foundation footing, blockwall, wall paint, floor
tiles. This also means more furniture and interior decoration items to
fill up the space, bigger AC capacity and more lightings, bigger
generator KVA and more fuel demand.
So think about your project's
size and ask yourself if you need that Olympic sized sitting room. Go
ahead and reduce the space for the entrance hall, dining room, second
living room.

4) Experienced Professionals Good
design professionals may cost some extra money, but their input helps
in reducing the overall cost drastically. You need engineers who know
that since the walls are designed as non-load bearing you could use 6
inches for internal walls and save about 20% on cost of blockwall. You
need architects who can design a house that doesn’t have the fanciful
columns, facade and roofs but still achieves a design that is simple to
construct and exceptional in appeal. This comes with experience acquired
over time.

5)Materials Quality and Quantity Endeavour
to purchase construction materials like cement, sand, granite, wood and
reinforcement bars yourself as most many Nigerian contractors tend to
add excess mark-up. Once you get the quote from the Quantity Surveyor do
your findings on where you can get the products.
If you find
going to your building site overwhelming, you can check sites like
cribpark.com where they give the prices of these items for each unique
location. Discuss with the contractor so you will know when the items
would be required, and in which sequence they should be delivered. Your
contractor will help you plan your materials inventory properly as all
materials cannot be supplied at the same time due to space constraints
and security challenges
If you are delegating the materials
purchase to suppliers, don’t go just go on a whim with either the first
estimate or the lowest estimate. Make informed decisions to get the best
quality and required quantity of materials your building needs.

By
following the above listed and proven tips, over time during the
construction stages, you will realize that you have saved a good money
much less than you planned. This is where you need to be disciplined.
The temptation is to spend the money so far saved on aesthetics things
like chandeliers, floor tiles and more. Remember your aim is to save
money, not to redistribute it on other aspects. Don’t go visiting luxury
building materials stores where you won’t be able to resist the urge to
overspend. Be focused and stick to plan.
Remember! If you don’t own a house, you don’t have a permanent address. The best legacies are the ones we build
Best wishes!
