If money were no object... This open railing + screening combination looks sharp. Love the minimally obstructed views of the yard from inside the house. The mini-trellis would have to be carefully designed so as not to look top-heavy over such a "light" railing. I have a photo of similar screen set vertically, w/vertical metal ballusters in the railing, equally nice. I think this railing would work fine w/orthagonal lattice below, too.
Tangential....one idea for the side fence, if there is to be a fence (vs plants).
