Pre-Construction. To be built. Pre-Construction. To be built. Penthouse living, perfectly scaled. Penthouse 3 occupies the northeast corner of Level 28 - the highest residential floor of the Roche Bobois St. Pete Tower, the first Roche Bobois-branded residential tower in the United States. Three bedrooms and three full baths span 1,763 square feet of interior living, extended by 323 square feet of private terraces - including a dramatic 43-foot terrace running the length of the living and dining rooms, where sunrise over Tampa Bay gives way to the sparkle of the downtown skyline at night. Interiors carry the Roche Bobois Paris signature: 11-foot ceilings, floor-to-ceiling impact glass, and a designer kitchen with integrated appliances. The 5th-floor amenity deck spans 20,000+ SF of resort living - heated saltwater zero-edge pool finished in artist-designed mosaic, a glass-edge spa cantilevered over the Art Plaza, hot and cold plunges, dry sauna, and private massage rooms (a couples massage is one concierge call away), a fitness center with sunrise cardio, cabanas, fireside lounge, and twin summer kitchens. Residents enjoy 24-hour concierge, a dedicated vehicle concierge, and an owners-only lounge with private terrace linked under cover to the tower's restaurant space. With a rental program allowing up to 12 leases per year (30-day minimum), Penthouse 3 rewards its owner from day one. The Joy of Living Differently - at the top.
