How To Calculate The Numbers Of Blocks And Cements Needed To Build Your House.
Building a house is the dream of most Nigerians both home and abroad, and one of the fundamental challenges majority of these people are faced with is planning ahead and knowing the quantity of various materials that would be needed to put their dream house to reality. This thread would be dedicated to treating extensively a DIY approach on HOW TO CALCULATE THE NUMBERS OF BLOCKS AND CEMENTS NEEDED TO BUILD YOUR HOUSE.

This DIY(Do It Yourself) approach is not aimed at stopping you from hiring a professional to have a perfect work done, but just to give you an insight on how individual professionals arrives at concluding numbers of quantity of materials required or requested for. This will also help you to know when a particular Engineer, Architect, Builder, Manson, etc are been realistic and not only trying to rip you off your hard earn money.
NB: This is just an eyes opening thread. You might eventually need the help of a professional at the long run for more complex aspects that can’t be treated on this thread.
The First section would be dealing with the block aspect and the numbers of contribution from people and their interest would show how soon the cement aspect would be treated.
We have different types of blocks in vogue in Nigeria and in diverse sizes. We have the solid block (no hole in-between) and we equally have the hollow blocks(the common type you get from block industries in Nigeria with holes in between).
They come in various sizes, 4” or 4inches, 6” or 6inches, 9” or 9inches. We would be treating extensively the 6inches and 9inches because they are in vogue and are majorly used as partitioning walls and external walls respectively. This thread won’t be breaking down the use or importance of individual types of block and sizes but only aimed at addressing quantity.
What does 9”, 6”, and 4” means?
The only physical difference seen in the above sizes of blocks is in their thickness. From experience, the 4”, 6”, and 9” blocks have the same height, and same length.
