Pre-Construction. To be built. Pre-Construction. To be built. This is the residence that shattered Tampa Bay's condo record: a $13.2 million duplex sky penthouse crowning the very top of the first Roche Bobois-branded residential tower in the United States. Spanning two floors at the building's southeast corner, Sky Penthouse 1 unfolds across 4,840 square feet of interior space and 1,770 square feet of exterior living across three private terraces, for 6,610 square feet in total. An internal grand staircase rises through a double-height foyer into the Great Room, a 27-foot double-height space wrapped in floor-to-ceiling glass on three exposures: east, south and west, with 12- to 13-foot ceilings carrying throughout the rest of the residence. The kitchen is appointed with premium cabinetry, precision millwork and state-of-the-art appliances, finished with custom stone countertops and designer lighting throughout. It's the only kitchen in the building with a walk-in pantry, opening onto the eat-in dining area and Great Room beyond for easy entertaining. A separate family room and den provide space for a bar, an 8-person gaming table, and a TV lounge. This stunning residence features five bedrooms, five and a half baths. Every bedroom is a full en suite with a private bathroom and walk-in closet. The primary suite occupies the entire second level, nearly 1,000 square feet including its own 170-square-foot private terrace. Residents of the tower have access to a heated, saltwater resort-style pool with a zero-edge design that appears to spill toward the skyline, its floor finished in hand-laid mosaic tile, the only pool of its kind in Florida. A sun shelf and dedicated swim lane sit alongside a glass-edge spa cantilevered over the Art Plaza below. The pool deck adds private cabanas, a fireside lounge and dedicated summer kitchens for entertaining. A private wellness suite offers hot and cold plunge, a dry sauna and treatment rooms, alongside a fitness studio with sunrise-facing cardio/yoga space. An intimate Owner's Lounge connects directly to the tower's restaurant, and residents enjoy 24-hour concierge, dedicated vehicle concierge and cold-storage package service. Delivering 2029, this duplex penthouse stands as the definitive residence in downtown St. Petersburg's Innovation District.
