I went with 2' centers 2x6 (its mostly rough cut white oak) on the little room next to the shop. 10'x16' joist run the short way, fully supported by the pad of the shop on one end, joist hangers, sistered joists on the front, back and 2 centered joists where the posts go down through. Both ends uses pt 6x6, the end twards the wood shed has 2 6x6 sistered since it's supporting the roof of the room+ the main 4x12 beam for the wood shed side. The middle posts in the room side are pt4x6. Outer 6x6's sit on 12" concrete pillars 4' in the ground, center 4x6 sit on 8" concrete pillars 4' in the ground. 1
Topped with 1" white oak boards. Plenty enough for any weight I can throw in a "man cave" room.
