An incredible combination of curving lines and circles in this ultramodern design makes for an interesting floor plan. The dramatic use of balconies and overlooks highlights a first-floor gathering room, with a fireplace, open to the study and a formal dining room. A kitchen with a circular breakfast room continues the gracious use of curves. A goblet-shaped bedroom on this floor has a balcony and a full bath. Reached by a curved stair, the upper level is dominated by the master suite. A lower-level activities room with a bar and fireplace, and an exercise room with an attached sauna, hot tub and bath overlook the lower terrace. Take special note of the generous use of skylights throughout.
