The panels and trim are both fiber-cement but the Hardie battens are a different color than the Nichiha panels. It will be much more subtle after it's painted.
Note the lower batten that is in-line with the bottom of the metal siding. The siding on the kitchen cantilever is nicely aligned with the metal siding along the deck. This also happens to be the height of the railing that will be installed on the porch. A modern/minimalist design doesn't have any ornamentation (or gingerbread) to break up the structure so small details are a big factor in the overall appearance. Alignment and proportion are key elements in Modern design.
Kudos to Chuck, Tracey and all the craftsmen making the details come out right.
I'm getting kind of attached to that big red dumpster. Maybe we'll keep it as a permanent lawn ornament.
