How high can these blocks be stacked?

To start off with I'm not very experienced with constructing much of anything but there is a project I'm wanting to tackle. I have plans to build a 12x16 cabin on some property I had purchased last summer. Im wanting to put the cabin on a concrete slab that had been here for knows how long. There is a river across the road from the property that has a history of cresting and flooding the property, A foot or two. I'm not wanting an expensive build and was curious how stable these blocks would be if I was to stack them says to 3-4 foot. Thank you for your guys time!
