@Clunk: Unfortunately it's a limitation of the shader I used for these. I didn't want them to have a weird concrete base, and the shader to avoid that doesn't support snow sadly.

I have several of your container stack sets, both this style (useable storage) and the plopable decoration building type. In Snowfall only snow sits on top of the 'Large container stack building' types, not on top of these, e.g. 'Container storage large stack 2A' has no snow. So they look a bit odd and mis-matched when situated close by or next to each other. Other than that - I like them a lot!
