Looking for advice on constructing ISBU in Bradford, NY!

Hello everyone! I'm still fairly new to this site, so forgive me if I am somehow in violation of a rule.

My fiance and I recently bought 3 acres in NY. The area in which our land resides, luckily isn't zoned at all! I can literally build whatever I want however I still must follow NY State building codes if I see fit to call the property my residence. There are certainly a lot more than I care to suffer through. Thus bringing me to my post!

About the only thing that I was able to find relevant to my situation was that I need 6 inch walls. Now I understand that if I don't call it my home, and give it some other name such as a garage or similar, I won't have to abide by these rules however, I think that because of where I'm at geographically, it might make sense to build to spec so that I'm not hating myself every year when winter rolls through.

So, I'm open to suggestions, preference to those with experience building in the area already however I'm open to anything!

Thanks!!!

Lets see you are building with shipping containers for stuctural walls, they can be stacked 7 level each filled with goods/cars/etc.
After that you need insulation. Stray bale or try some of that R20 spray on insulation on the outside, its expensive though.
On the inside you could use some more or something cheaper or no insulation.

You could also build a wrap around porch/sunroom/greenhouse for heating(winter) and cooling(summer).
If you go with the greenhouse just be mindful of the humidity.

If you are going to put the ISBU on slap it would be nice if it was extra big.
And the shipping guys could just drop them off on it and then you would only have to move them a few inches to align.

When you cut out the windows, doorway and archway(living/dining room) you are going to have to use a milling drillbit vs a saw or something
