About This Home

For the one seeking a feeling that is almost impossible to describe. There are oceanfront residences. And then there are those that simply cannot be matched. Occupying an entire floor at Le Sanctuaire, this extraordinary penthouse is one of only four residences and one of South Florida's rarest private offerings. Reimagined by the building's original developer and fully restored in 2024, every detail reflects a standard of craftsmanship defined not by trend, but by permanence. Arrive by private elevator to a vantage point rivaled only by being at sea. Simply: 180 degrees of uninterrupted Atlantic Ocean, framed by Maxi-View SSG floor to ceiling impact glass. From sunrise onward, the ocean becomes part of the architecture. Stained white oak ceilings, sculptural Calacatta marble, backlit natural crystal quartz, and a bespoke chef's kitchen establish an atmosphere of quiet distinction. The oceanfront primary suite is a private sanctuary of its own, with a boutique-inspired dressing room and a spa-like Dolomite marble bath centered around a freestanding soaking tub and illuminated, book-matched Australis marble. Beyond the glass, expansive terraces, a motorized pergola, private Jacuzzi, dedicated cabana, and lock-and-leave service create an experience that feels less like a penthouse and more like a private estate suspended above the Atlantic. One floor. Only four residences. An entire horizon. Some luxuries can be acquired. Others may never exist again.
