Hello,

I am with Tim...The first thing I thought when I read the configuration was "Dutch Barn" and I am unclear about why you would need such a huge timber anyway? Traditional barns seldom have such clear spans until you get into "truss designs" (which are very rare) and/or "bull beam" barns which are only slightly less common (not many) to vintage Dutch Barns.

On specially projects like this one can "site select" enough trees this size to achieve that span, but I would say a PE stamp is in the future for such design and would rather suggest not "reinventing wheels" and sticking with "traditional barn formats" and layouts...Like a Dutch Barn which often had 16/12 or 12/12 pitched roofs historically.

Feel free to drop me an email or call if you would like to talk more about these vernacular styles...

Regards,

j
