Thanks Christopher,do you suggest only white oak because white oak is quite expensive and it seems that we dont plant it much anymore due to its slow growing nature. Also my sills need to to be quite long which seems more difficult to obtain for white oak as opposed to pine. Where are you located in relation to me in Ulster county because I am looking to find an engineer that I could consult with about a Dutch barn on lime mortared foundation I plan to put up in Saugerties,NY(just East of Woodstock, with slightly less ridiculous building codes). I have some design questions regarding a few adjustments to the traditional New World Dutch barn(anchor beam) design. Based on reducing the proportional dimensions of the usual 45-50 feet width to 30-36 wide bents. I will eventually like to have an engineer approve my finished frame plans that I plan to draw myself. Does that sound absurd?? Perhaps there is a way we could get in contact and I could better explain my situation. Thanks again tb
