I love the renders in the initial post of this thread by Urban Dave.
Does anyone know if Urban Dave's renders are conceptual @ this stage. Most if not all of them do so, really. Urban Dave, do you know?
I also love Jean Nouvel's earlier works especially his usage of expansive glass with intricate motifs. One being of his Arab World Institute, on Paris's Left Bank completed in 1987
