My barn (glorified shed)

Well there's ur problem!

I used a lolly col in each corner to lift the barn

One of the old posts that used to support the center

Shows the garage door elevated off the ground

 I built four large beams to go under the ceiling joists and the top plate of each wall.  I then lifted the large beams with adjustable lolly columns.  Next step is to fix up the foundation adding some height so the wood is not so close to the ground.  Then I'll add a pressure treated sill.  Once that is done I'll replace the old posts in the center with permanent steel lolly columns.
