In Nigeria, most people consider fencing their property a priority. Apart from helping to secure your property from the menace of omo onile, a fence also serves as a boundary, provides a level of security and it also adds aesthetic value to your property. You also get more privacy in a fenced apartment. Whether you’re cooking, eating, bathing or just sitting outside your property, you’re sure no one is peeking.
Types of Fences in Nigeria
Wrought Iron fence: this is mostly used for the fencing of estate entrances. This type of fencing provides aesthetic appeal but requires regular maintenance.
Wood Fence: this type of fence is common in North America. However, home owners in Nigeria use this type of fence to separate the main building from back yard farms or poultry. It can be a cheap option depending on the height and type of wood.
Aluminium fencing: this type of fencing isn’t common in Nigeria and for obvious reasons. It is not as “strong” in terms of security. It is usually used as a temporary option before a “real fence” is installed.
Chain link / Wire mesh: this type of fencing is commonly used to make barriers in parks and across the roads in Nigeria. It is very durable and low maintenance option.
Electric Fencing: this type of fencing is used in places that require high level of security. It is commonly used by the elites in Nigeria
Bamboo: this type of fencing is gradually becoming a trend across developed nations of the world. Bamboo fencing is very durable and offers total privacy (although, it will still take a while before it gets accepted over here)
In this guide you’ll learn how to calculate the number of blocks needed for a fence in Nigeria. Although there are different types of fences,the most commonly used type in Nigeria is the concrete fence. This guide will be based on the number of blocks needed to build a concrete fence in Nigeria.
Cost of Fencing a plot of land in Nigeria
A standard plot in Nigeria measures 120 feet by 60 feet. Therefore, we’ll be using this measurement to determine the number of blocks needed for a plot in Nigeria. However, if you have 2 plots of land, all you have to do is multiply the final results in this guide by two. If you have 3 plots of land, multiply the final answer by three. However, if your land is half plot, just divide the final results in this guide by half.
This guide contains basic principles of mathematics: addition, multiplication and conversion. Even if you hate mathematics, the guide is pretty easy to follow.
Plot of Land
Firstly, we’ll calculate the perimeter of the land and convert to inches
Since the standard measurement of a plot is 120ftX60ft, this means:
Length = 120ft, the length has two sides ; ( 120×2 = 240)
Therefore length of both sides (total length) = 240ft
Breadth = 60ft, the breadth also has two sides; (60×2=120)
Breadth of both sides (total breadth) = 120ft
From basic mathematics, Perimeter = length + breadth
Perimeter of the plot = 240+120=360ft
To convert to inches, we use the standard unit of conversion
1ft = 12 inches
Therefore 360ft = (360×12) = 4320 inches.
This means, the total length of a plot of land measuring (120ft x 60ft) is 4320 inches
There are two standard types of blocks in Nigeria, 9 inches block and 6 inches block. But, don’t be fooled by the names, both the 9 inches and 6 inches block measures 18 inches in length.
Now, we’ve gotten the measurement of the land and block
To get the number of blocks that will go round the whole plot, we’ll divide the land by the block
i.e 4320/18 = 240 blocks
This means 240blocks will go round a plot of (120ft x 60ft). However, to raise the fence to the desired height, we’ll have to multiply by the number of coaches.
Most home owners usually prefer a fence that’s about 7 feet tall. A 7 feet fence equals 9 coaches.
Therefore, to get the total number of fences for 9 coaches, we’ll multiply the number of coaches by the number of blocks that’ll go round the plot.
This is 240 x 9 = 2160 blocks
How many bags of cement to build a fence in Nigeria
The standard calculation of cement to blocks is: one bag of cement to 70 blocks ( please note that the number of blocks can be less that this if you’re using hollow blocks)
Therefore, for 2160 blocks, you’ll need 2160/70 = 30.86 bags of cement or approximately 31 bags of cement.
Other costs include
Digging of the fence foundation – N20,000 – N30,000 ( depending on your location)
A truck of granite – N120,000 ( for wall foundation)
Cost of labour: depending on the area and your negotiating power , it can between N40-N50 per block for bricklayers and N20 –N30 per block for labourers
Cost of plastering fence in Nigeria
To plaster a fence in Nigeria, you’ll need 2 truck load of Plaster sand.A truckload varies between N25 -N35,000 (depending on your area)
About 20 bags of cement(Elephant/Bua) for the interior,and about 10 more for the exterior. (depending on design )
