I have home with living space on the 1st and 2nd floor and walkout basement. I am planning on renovated the basement into a family room, but I have 4 lolly columns, 2 of which I would like to remove to open up the space of 20' span. My question is what size laminated beam would I have to install to carry the load of the 1st and 2nd floor or living space with a 20' span?
