How To Calculate Number Of Blocks For A House

How To Calculate Number Of Blocks Needed For Your House

Estimating the number of blocks for your new house can be challenging, while it must not with this easy method.

Estimates from masons normally do not match the level of work to be done and sometimes the blocks requested are significantly more than the level of work.

This easy method proves to be a means for even lay people to determine the number of blocks needed to complete any number of rooms or any type or form of building design or building plan.

If this approach is followed appropriately, the number of blocks that would be left after the completion of work will be less than twenty (20) blocks.

The things and/or figures you need to estimate the number of blocks needed for your building are

1. a sketch of your building on paper or on a floor. Others who have building plans drafted for them could equally use that.

2. an estimated dimension or length of all sides of the sketch or building plan

3. the length of one block that you wish to use for the building, since there are different lengths of blocks available. However, for ease of calculation, people can use the standard 0.45 meter block which is converted to 1.48 feet.

This simple estimation of blocks aims at finding how many blocks would be needed to be laid around and in-between to cover the total perimeter or total distance along the building walls’ pathway. Since a building takes sixteen (16) courses (that is 16 blocks lying on top of each other for the building’s height), when an individual is able to determine the number of blocks needed to be laid around and in-between the building’s pathway, the same total number of blocks to be laid around and in-between for one course to be estimated will be multiplied by sixteen (16 courses).

To find the total blocks to lay around the building walls’ pathway

1. add all the length of every side of the building sketch or building plan, including the in-between lengths, and take note of the unit you have measured and add the total length. For example, for two rooms with dimensions of 14ft by 13ft, we would have a total building walls pathway of 14ft + 14ft + 14ft + 14ft + 13ft + 13ft + 13ft = 95ft

2. Divide the total perimeter or total building walls pathway by the length of the block you want to use. In the absence of any particular block, divide by 0.45m if you have added the total length in meters or divide by 1.48ft if you have added the total building walls pathway in feet. On this calculation, that will be 95ft √∑ 1.48ft = 64.19 blocks. This example implies that the building will need 64.19 blocks to lay one course around and in-between the building pathways.

3. In order to calculate the total blocks needed, you must multiply the figure that is gotten at point two (2) by 16 courses. In this case, 64.19 blocks x 16 = 1027 blocks. The total blocks needed, therefore, is 1,027 blocks.

4. This calculation does not subtract spaces of doors and windows from the total figure arrived at point three (3) because such number of blocks for windows and doors is considered as the percentage of blocks that would be broken during work.
