Can you elevate a slab on grade foundation?

I'm building a home up north in Parry Sound, Ontario next year. I'd like a slab foundation raised three feet above the ground level. I'd like to have a wrap around porch.  So aesthetically I think it looks better than being on ground level. As well because of snow accumulation. 

My question is what would be the best way of constructing such a foundation? Or if it's even possible? I'd like the insulated slab on grade foundation idea but just wondering if elevating it 3ft. is possible? or is going with an ICF foundation, going down below frost level (4ft. Up north) a better route? Or do you suggest something altogether different? 

Keeping in mind I'm trying to build as Passive House as possible. 

Thanks

Raoul
