Not an expert on pole barns but IIRC the poles a sunk far enough so that
they provide the lateral shear strength. That means they have to go in
3' to 5' depending on how big your building is. Plus you may need to
pour a concrete 'collar' around each pole.

A good gravel base will work fine until you get enough extra $$$ to pour
the floor later. Make sure that you grade things, set the collars, set
the driveway, etc so that it all works out right for the later concrete.

There are lots of suppliers that will create a plan, sell the materials,
and deliever to your site. In the midwest Menards is one of the bigger
suppliers, each of their stores has a kiosk and computer to let you
design what you need.

For residiential area buildings, be sure to look into some of the
various colors. Pay the extra few bucks to get something other than pure
white. You will also want to design something with soffets and other
trim to make it match the house.

myself. has to have gravel as I am on a limited budget. Will be
adjacent to my house.

What is the cheapest way to go about this and make it look nice?

Is it ok to use 4x6x12 posts 2 feet in the ground?
