We will be building a walkout single story home. We have a deck on our main level with stairs down to the bottom level and back yard -- pretty typical.

Just curious what you all put under your deck? I've seen some that put concrete under it or pea rock and just put storage bins for balls, sports equipment, etc.. I've seen one family that put the kid's sandbox under there.

Pictures? We are considering actually enclosing this space to put the lawnmower and stuff so our garage is more usable for cars, but unsure if this is wise.

Thanks!
