After putting the finishing touches on the Sheikh Zayed Grand Mosque in Abu Dhabi, architect Olivier Sednaoui met antiques collector and interior designer Amr Khalil at a party and was tasked with designing a mansion full of life, home to myriad stages for entertaining guests and acting as the perfect springboard for exploring the best of El Gouna. Looking to a handful of European landmarks for inspiration — from Saint Mark’s Basilica of Venice to the Minoan murals of Santorini and Barcelona’s Palace of Catalan Music — he set about to transfix the attention of the onlooker through a palette of rich materials and an imaginative use of light and shadow within a classical, rational-style building.
