From West Palm Beach, where she oversees her design studio, to Key Largo, interior designer Gil Walsh understands the South Florida sensibility like few other aesthetes. For one Ocean Reef project, the dining area features cylindrical brass chandeliers from Solesdi that spill rings of LED illumination over a custom, crackled glass-topped table. Beyond Florida’s magical light, Walsh’s inspirations include Lake Como, Provence, her Martha’s Vineyard showplace—and Oscar de la Renta.
