I am restoring the barn to as much original as possible. The foundation will meet local codes either way I build it. I just thought that the pilar style would provide more strength even though I would not technically need it. It also would allow me to secure the posts will huricane straps in the concrete. They recommend 3" of clearance from the wall edge.

As far as the "Dutch" style barn goes I am not 100% sure. The barn is 52 x 40 and has rows of queen posts. Even though these barns seemed to be common in New England in a much earlier time this barn seems to have the same design but was probably built in the early 1900's. I live near Lynden WA which is a Dutch community so I assumed that maybe it was. If I am wrong or if there is a way to clearly identify please let me know.
