You need a column where beams meet perpendicularly. So, on the lower level, you need a colum where the beam at the west of the entry runs into the beams running east/west along the common area. I hope that makes sense. Also, I don't think you need a beam on the upper level east end of the common area since the joists are running the same way. But you DO need a column at each end of the upper level beams. Cantilevered beams aren't allowed.
