The cost of constructing a perimeter wall in Kenya depends on the quality of materials used and the height of the wall.To construct a perimeter wall in Kenya is not cheap, for a 50 by 100 plot, you will spend Ksh 400,000 to Ksh 600,000.To construct a perimeter wall on 100 by 100 plot, you will spend Ksh 600,000 to Ksh 900,000 depending on the height of the wall and quality of materials used.
Here is how you can calculate the number of stones needed for erecting perimeter wall for a plot of 100×100
Foundation stones:
To calculate the amount of foundation stones needed, you will need to find the perimeter of the plot. In this case, it would be:
100+100+100+100 = 400 feet
Assuming you want to lay 3 courses of foundation stones, you will need:
400 feet x 3 = 1200 feet of foundation stones
Walling stones:
To calculate the amount of walling stones needed, you will again need to find the perimeter of the plot:
100+100+100+100 = 400 feet
Assuming you want the wall to be 10 courses high, you will need:
400 feet x 10 = 4000 feet of walling stones
To determine the number of machine-cut stones needed, you will need to divide the total length of walling stones by the length of one machine cut stone which is 1.3 feet. Then:
4000 feet ÷ 1.3 feet = 3076 machine-cut stones
You may need to subtract a certain number of stones to account for the gate and columns, depending on the design of your fence and wall.
So, for a 100×100 plot, you would need approximately 1200 feet of foundation stones and 3076 machine-cut stones (minus the amount needed for the gate and columns, let’s say 200pcs) for a 10-course perimeter wall.
The perimeter wall needs a gate, will cost you Ksh 70,000 to Ksh 250,000 to construct a gate. You also need to do finishing which costs Ksh 100,000 to Ksh 200,000.
The cost for paying fundi is Ksh 80,000 to Ksh 200,000 depending on the size of the wall. A 50 by 100 wall requires 60 to 80 bags of cement and 100 by 100 wall require 100 to 150 bags of cement.
For a 50 by 100 plot, you will spend Ksh 150,000 to Ksh 300,000 on stones. To buy stones for 100 by 100 plot, you will spend Ksh 250,000 to Ksh 400,000.
You also need steel bars which will costs Ksh 100,000 to Ksh 200,000 depending on the size of the wall.
So,if you are planning to construct a perimeter wall for 50 by 100 plot, you must have a capital of Ksh 400,000 to Ksh 600,000.To build a perimeter wall on 100 by 100 plot, you will spend Ksh 600,000 to Ksh 900,000.To construct a perimeter wall on half an acre plot, you will spend Ksh 700,000 to Ksh 1.4 million. Constructing a perimeter wall on 1 acre piece of land, you will spend Ksh 1 million to Ksh 2 million.
