Where Two Penthouses Become One Beachfront Estate in the Sky. At the top of the exclusive Colonial Club in Coquina Sands, two penthouse residences have been united to create an extraordinary Gulf-front estate spanning 3,518 square feet. Set within one of Naples’ most intimate beachfront buildings, with sweeping views of the Gulf and a setting that is nearly impossible to replicate. The seamless combination of two penthouses—601 and 602—delivers approximately 3,500+ square feet of refined beachfront living, blending the scale of a private residence with the ease and security of condominium ownership. Residence 601 offers approximately 1,760 square feet under air plus a covered balcony, distinguished by its coveted end-unit position and additional windows that fill the home with natural light. Designed with timeless modern wood cabinetry and a neutral palette, this residence includes three bedrooms and two bathrooms with walk-in showers and understated finishes, creating a calm and inviting environment suited for both everyday living and entertaining. Residence 602 presents a beautifully reimagined residence with approximately 1,758 square feet of thoughtfully designed living space. The home features top-of-the-line appliances, quartz countertops, all-white custom cabinetry, and elegant designer lighting throughout. Spa-inspired bathrooms evoke the look of a Carrara marble finish, while the layout includes a spacious primary suite and a flexible office that may serve as an additional bedroom. Together, a rare dual-penthouse configuration that lives like a single-family beachfront home in the sky. The combined layout includes four bedrooms plus a den, two expansive living areas, multiple dining spaces, and two glass-enclosed lanais that frame sweeping Gulf views and unforgettable sunsets from multiple vantage points. Set within the intimate Colonial Club, a boutique Gulf-front building of only 18 residences, owners enjoy a quiet, private atmosphere enhanced by full-time on-site management and a community of seasonal residents who value discretion and relaxed beachfront living. Ideally located near Lowdermilk Beach, Fifth Avenue South, Third Street South, Miracle Mile, and the newly opened Naples Beach Club at the Four Seasons, the residence is also positioned within Naples’ emerging luxury corridor, where new landmark developments continue to elevate the coastal lifestyle experience.
