Our backyard currently has a large section that currently occupied with garden beds. I want to remove some of them and put a shed on it where the sidewalk goes to for an office/guest space.

It’s currently covered in stone, but actually has a concrete slab underneath the stone.

How should I prep the area since the shed will be smaller than the concrete footprint? Should I go on the rocks or just straight on the concrete slab?

Very new to this, so feel free to answer like I know nothing about sheds, ventilation, etc.

Thanks!
