    A little more info needed

    Is there going to be a load on top of this span?If so,how much weight.

    How long is the loft,I see 16'6" wide.

    What is below this span,is that the wall you spoke of?

    you'll need a microlamb beam, you'll need to call a homecenter and get in touch with a structural engineer to tell you the size beam you'll need. My guess is a double 2x 16 by the length you need
