A spiral staircase seems to rise out of the pool and a rooftop-deck glass floor seems to float above the ground at this contemporary villa among the Bali rice fields. Its angular steel and glass lines are softened by wood-paneled ceilings—and by the staircase curve as it leads toward 360-degree views. In 10 minutes you can be ordering a coffee or on the massage table at a spa in Seminyak Square.
