Six Senses Southern Dunes, The Red Sea

Foster + Partners shaped the buildings here to mirror the dunes themselves, low and curved, so the resort seems to rise out of the desert rather than land on it. Six Senses Southern Dunes is a remote luxury resort on Saudi Arabia's Red Sea coast, running on solar power with its own water plant. Private pool villas open onto unbroken desert, the spa fills two floors with hammam and hydrotherapy, and the cooking school leans into regional flavors.
