Structurally, I hate to add columns in my work space. Either support the loft with clear span beams or hang it from the rafters.Remember the posts that are supporting the mezzanine floor joist should sit directly on top of 4x4 post. No "thru bolting" of joists to posts !! These post really should rest on top of a full depth "foundation" not just on top of the floor ! Your life depends on this !!!
Just like build a deck that people are going to be standing on.

As far as what to put in the loft, we don't know the OP's passions. TV? Wet bar with beer on tap? Model railroad? Knitting?![]()
