Hello. I am in the process of designing a timber frame shop with a house above. I am wanting the shop to have as much open space as possible with as little posts as possible. I would like to have a min. 32' clear span but am wondering how to do this. I know I need to consult an engineer which I will, but would like to see if anyone has any good ideas. Am I pretty much limited to truss floor joist or tji...?
Thank you for your time,

Nathanael
