There are two columns in a hut that is 4,5x4,3 meters, there is a beam on top that goes from inside of one wall to column that im planning on replacing because of its age and second beam that is about one meter wide that goes from the column to another wall. The problem is the second column looks like it is supposed to hold the roof (roof is very thin therefore light) but it was probably placed so the wall between those columns wouldn't fall (wall was made out of windows and some sort of cement that was attached to these columns by nails)
