Though I've read through other threads and enjoy the content!Consult a structural engineer or a competent contractor to assess whether this setup is technically sound and will prevent drooping or bouncy floors. They will be able to evaluate the load-bearing capacity of the 4x6 joists, their connection to the 2x6 top plates, the use of LVL beams, and the inclusion of steel I beams for increased rigidity.
I am building a second floor to a barn that I have and I'd like to span 16' with 4x6 joists. I am wondering if this is doable. They will be rough sawn true 4x6.
The space is a 30'x16' room and I'm trying to avoid having to use center posts. The 4x6 joists will be tied into and sitting upon 2x6 top plates. The 30' will be split equally into two separate rooms and I'm going to use a large LVL in the wall space between the rooms (as in the LVL will span the 16' halfway through the 30'). I also thought that I could incorporate 3x5 steel I beams into the joists for added rigidity (and box them in with rough sawn lumber).
What I'm wondering is if this is safe, will they sag, springy floor? I am going to put 2x6 tongue and groove flooring on top. The reason for the short 6" heigh is a space shortage above.
I appreciate any and all insight.

First, thank you for creating this detailed post on your build of the universal cottage! It has really inspired us and answered a lot of questions. We are looking to build the same house but just extend the length to 36ft. We will be building in Maine so the climate will be similar to yours. I think the main differences we are going to make is using roof trusses 7:10 pitch and Ijoist floors. I'm considering 16 oc framing instead of 24 oc. I see a lot of mixed reviews on 24 oc framing (straightening the walls is harder, walls shake when doors are closed, etc).
I'm just curious how your house is holding up. Is there anything you would have liked to have done differently during the original build? Have you encountered any moisture issues? Any recommendations you would make to someone who wants to build this same house?
