The middle third would've included a loft storage area.
Opening up the interior necessarily involves the type of truss we employ. If possible, I'd love to avoid the standard truss, with its horizontal bottom chord. After some text conversation with my designer/builder John Hockman about it, it looks like parallel chord trusses like those in the photo below (not my studio in progress) would be the most ideal to conform to those wishes.
Speaking of "peace out", I really ought to do the same.
