Do you guys have any pictures of what you are talking about. I'd like to understand but am having a little hard time picturing by the description. I am particularly interested because I plan on building my own timberframe withing the next couple years and am planning it now. I am not planning to have a basement so I am trying to figure out what type of foundation I need for my frame. Initially I was thinking on a slab, but then how do you route plumbing and electrical and heat/AC? I'm now thinking that a crawlspace is needed. Any opinions or pics? I think this relates to the mounting of the posts in that it raises the question of how the pluming, electrical and AC/Heat will be handled. thank you, Brad
