Inside, an extraordinary palette of natural stone, warm wood, expansive glass, architectural lighting, and hand-applied Venetian plaster across the walls and ceilings creates an atmosphere of understated sophistication. Among the home’s most distinctive features is a more than 20-foot natural travertine wall wrapping an entire corner of the residence, bringing remarkable scale and texture to the interior. The chef’s kitchen features expansive Calacatta stone surfaces, custom cabinetry, integrated appliances, and a substantial waterfall island designed for both everyday living and entertaining. Expansive glass opens the principal living spaces to generous covered terraces, a pool and spa, and multiple outdoor gathering areas overlooking the waterfront.
