This barn was built with Rough-Cut Oak wall frame on top of concrete foundation/slab. Floor joists were hung between LVL beams and walls using ledger boards and joist hangers. Loft has 24" knee-wall to provide extra headroom inside of loft. Roof 2x8 rafters on this barn are spaced 24" o.c. and supported by double 2x12 knee-wall headers. Loft supporting clear-span beams are held in place by specially designed steel brackets.
We now have architectural plan available for this barn built with regular conventional framing (2x6 stud wall on top of poured concrete foundation). See BP16 Barn Plan
