How Many Cinder Blocks to Build a 1500 sq ft House?
Building a house is an exciting project. Everyone has their own dream house in their mind. Some people like to build a house with Cinder Blocks. However, it is an interesting project but it requires advance planning.
If you’re planning to build a 1500 sq ft house, the key question is how many cinder blocks to build a 1500 sq ft house? Don’t worry, we have got you covered in this planning. This article will guide you on how many cinder blocks you need. Calculate the number of cinder blocks for the floor and walls separately. In this way, you can manage your project more efficiently.
What are Cinder Blocks?
Cinder blocks are also known as concrete masonry units (CMUs). These are rectangular blocks made from concrete and ash. They are generally used in construction because they are strong and durable. Cinder blocks are lightweight compared to normal concrete blocks. This makes them easier to use.
They are available in different sizes and shapes. These blocks can be applied to walls, foundations, and different structures. Cinder blocks additionally provide excellent insulation. It keeps homes warm in winter and cold in summer season. Overall, they’re a famous preference for many building tasks.
Size of Cinder Blocks
Cinder blocks normally measure 16 inches long, 8 inches high, and 8 inches deep (16″ x 8″ x 8″). However, there are different types that exist. Such as half blocks (8″ x 8″ x 8″). It’s important to note that sizes depend upon the requirements.
The cost of one cinder block of size (16″ x 8″ x 8″), ranges from $1.50 and $3.00. This cost can increase according to the size and thickness of the block.
Determining The Number Of Cinder Blocks To Build A 1500 Sq Ft House
Determining the exact amount of required cinder blocks is difficult. The amount can increase anytime because of any unexpected use or damage. You can also use some best Quantity Takeoff Software. This software helps you calculate the amount and costs of material needed.
But if you just need a rough estimate, following are some steps to help you calculate the number of cinder blocks needed for your house.
- Measure the dimensions of one cinder block.
- Calculate its surface area.
- Calculate the total surface area of the house.
- Divide the total surface area of the house by the surface area of one cinder block to determine how many blocks are required.
- Add an extra portion of cinder blocks for wastage and miscalculations.
- Also, consider if you want extra thickness for the walls. This will require more cinder blocks.
- Now you can calculate how many cinder blocks you need to build a 1500 sq ft house.
Calculating Cinder Blocks For The Floor
- Determine the size of the cinder blocks you need.
- Measure the surface area of the floor area.
- Calculate the area covered by one block.
- Divide the total floor area by the calculated area per block to find the total block area required.
- Add an extra percentage for any wastage or breakage.
- Round up the result to the nearest whole number.
- Buy extra blocks for unexpected need.
Calculating Cinder Blocks For The Walls
- Assuming an average wall height of 8 feet and a standard wall thickness of 8 inches, the calculations will take place like this:
- Calculate the total area of the walls
- Calculate the area covered by one block.
- Divide the total surface area of the walls by the area of one block to get the number of blocks.
- To determine the number of cinder blocks for a 1500 sq ft house, multiply the number of blocks above by 1500
- (Number of blocks) = 1500 x (Total wall area) / (Area of a single block)
Approximately, you would need 9,000 to 12,000 cinder blocks to build a 1500 sq ft house.
Remember that this is just a rough estimation. The total number of blocks can increase with the following factors.
- Ceiling height
- Wall thickness
- Doorways
- Windows
- Structural support
Cinder-Block Wall Finishing
