Geez - my first post was rather non-descript - I may have been drinking decaf.

The idea is to build a traditional timberframe building without the posts, braces or anything else below the plate. Instead of the frame relying on the posts to stay standing, I'd like the roof system to bear on the exterior concrete walls.

It would be nice to place an 8" timber directly on top of an 8'ICF (timber visible inside and out) but I would rather move the timbers inward to allow for insulation. I'm just curious how far 'in' you could move before you'd require a post to hold the thing up....
