Nice little project. Top comment has a criticism that seems to make a lot of horse sense about the cinder block being installed on its side rather than with “holes up.” Another mentioned putting gravel under the block rather than compacted dirt for better drain off and less chance for settling.

The whole project seems to have been done without any thought to water drainage. Idk why you'd want a garage without a concrete pad tbh anyways.

Putting the blocks sideways puts the bottom of the block in tension. Over time this will crack and the small center will be the only thing supporting the column, this will create a hinge in the base of the column. Next time it's loaded fully it will collapse. This is not speculation, it's math.

The exact criticism I was mentioning. Totally makes sense.

I heard 24" on center and stopped watching.

The reasoning is when calculating for deflection (bending due to load), unbraced length is taken to the forth power.

16 4 =65536 24 4 =331776

The difference in deflection can be roughly estimated relative to eachother.

331776/65536= 5.0625

The deflection on a plywood sheathing between studs is 5 times higher for 24" o/c vs 16" o/c.

I just don't see how that loss in rigidity is worth the maybe $800 in lumber savings over the lifetime of the shed.
