Exterior
I'm not totally sure about all of this yet. I just ordered the roof which will be light gray and have standing seams that run vertically. The same roof will be on the small bay window and garage. The company is called Fabral, and basically we gave them the exact measurements and they will make the metal roof for us.
I also decided I want the corrugated metal in the dark gray to run as a panel top to bottom by the loft windows on both sides. The cedar shingles will sit above the frieze board and be the material on the bay window.
As for the material for the majority of the house, I am not positive what I'll do yet. I like the board and batten look but I'm not sure whether a stained wood or solid color will look best. Whatever I decide, I will also cover the garage in.
Although this picture is from the interior, it shows that the 1-inch rigid insulation that we adhered to the inside of the Zipboard and then spray foamed the edges was just about right for the thickness of the board and batten material so as not to reach the interior. However, as you can see, the heat of the nails driven with the nail gun melted the insulation around each nail. Yowza!
