Foundation question

Next project for me is an 8X10' shed in the northeast. We get freezing temps, but I don't intend on frost-protecting the foundation, and it's not needed by code, either.

I've read of various foundations. I'm putting on a slight slope. I want to build this:

If the link doesn't work it's a box made of PT 4X4's and within it's filled with gravel and then the shed put on that gravel. It looks nice and a big bonus is no time spent dealing with weeds creeping under the shed.

What I want to do, however, is build that box but instead of filling with gravel and putting the shed on that simply placing the shed directly on the edges of the box, thereby ignoring the entire gravel situation. What's the drawback of that? It would save me a little space (room is tight) and obviously no need for gravel. I had planned on creating a very tiny berm at the uppermost part of the grade to direct water around the side of the box. There would thus be an air space underneath the shed without ventilation (but everything is PT anyway).

Also, I think this approach might let me not have to bother with landscape spikes as no lateral force whatsoever will be pushing on the box.

I think the link you provided assumes you would use the gravel base for the floor of the shed.
You'll likely have moisture problems without any ventilation under a wood shed floor although a layer of plastic on the ground might help. Wait and see what the others will say.

Can you use the cinderblocks and 4 X 4's for your base? This keeps our floor of the shed off the ground enough. We built our shed using one side of our detached garage as one wall. I don't know about freezing temperatures. We also put in a window with a screen - small size - but to ventilate it. We have extreme heat here and having that small window has been great. Shed was built eight years ago and still in great condition. So the foundation of our shed is make of wood.

I did not look at your link. I have no experience, but wanted to share ideas in case it makes you think of something that you had not before. Good Luck.
