How Many Concrete Blocks Do I Need for Shed Foundation? (Solved)

One of the most important parts of a shed is its foundation.

You cannot skimp on this.

This is why you will want to ask, how many concrete blocks do I need for the shed foundation?

It’s recommended to use 40 blocks for an 8×10 shed, 64 blocks for a 10×14 shed, and 80 blocks for a 12×20 shed. To get things right, always plan the layout and measure the concrete blocks. Once done, lay down the blocks and never cut down on the stability of the base.
