This bulbous structure isn't even 40 years old yet, but it's already been designated an historic monument by the French Ministry of Culture. Designed by organic architect Antti Lovag,
the home features panoramic views of the Mediterranean Sea and celestial views at night. A garden at the center of the home features a waterfall and stream with palm trees and exotic vegetation. Inside, space-saving furniture, cupboards, and shelving are built into the home. Believe it or not, this is not a unique property; Lovag has designed three others—including one for fashion designer Pierre Cardin—along the same coast.
