The luxury residential experience reaches soaring heights inside the Penthouse at Toscana's South Tower, an 18-story waterfront treasure in Highland Beach. This is a bespoke double-penthouse residence delivered as a single expansive unit. The sprawling residence dazzles with sophisticated, thoughtfully rendered interior vignettes courtesy of Judy Howard of J/Howard Designs. Look no further than the dramatic foyer that unfolds as the doors of your private elevator open, an elegant sea of travertine marble flooring inlaid with green Persian onyx, complemented high above by a circular ceiling recess from which an imported Italian chandelier hangs. It's the first glimpse into a lifestyle that artfully balances comfort, creativity and sophistication amid the splendor of an oceanfront backdrop. Indeed, natural light fills spaces throughout the penthouse, including a chef's kitchen with custom cabinetry, top-of-the-line appliances, a wine cooler and an elongated island that's perfect for entertaining.( The mammoth primary bedroom, with a sitting area near the window, further capitalizes on the views thanks to a cozy balcony overlooking the Atlantic. The first of two master bathrooms includes a large, walk-in shower designed with cocoa onyx; the second master bathroom features an inviting soaking tub with an east-facing view and another spacious walk-in shower. (In addition, the penthouse sports a media room, a billiards room, an office, a custom-designed bar, Lutron smart lighting throughout and two additional guest suites.( The South Tower at Toscana also provides its share of special amenities, among them: valet parking, an exercise room, a cigar room and card room, a resort-style pool and sauna, tennis courts, a barbecue area, and a separate beach club directly on the ocean.
