Oh, the barn condition is not perfect by any means. To save it would mean a number of repairs, though not impossible. You see the light in the corner? That corner is missing. The post is gone. Not sure what happened. about 1/3 of the floor you see is bad. Some damage on ends of some posts below and lower portion of siding. This barn is well ventilated currently. It would take a fair amount of work to repair, but as I said, could be done. It does have a very nice feel to it though the head room on the second floor needs to be increased. I'm 5'9 and someone 6 foot would some close to bumping their head on the tie beams. The first floor is dirt/mud floor where animals were once kept. Any post near the ground have some degree of damage or rot. As to their decision to take it down, well they decided that and we have no say in it. At least the materials will be reused and not wasted, unlike our very large family barn that had massive 20Xsomething 50 foot beams that sat out back and rotted after the barn was taken down. That was when I was 13. Had we only known better...
That is correct that I did not give enough information to determine if 6X6 pine were sufficient for a specific application, but I was just asking if they were commonly used in general. Of course for a specific application you'd have to calculate the load on a floor and how close you'd have to space them to acheive deflection within acceptable limits and bending stress with appropriate margin of safety(built into the loading actually).
