Dock approved. Located within a gated estate on the private island of Sea Island, secured by 24-hour security, “Villa Measured,” Cottage 509 sits on an exceptionally private .86-acre deep-water homesite—one of the largest and most secluded marsh and riverfront parcels on the island. Long, uninterrupted water views unfold in multiple directions, while the estate’s setting and natural buffers create a level of privacy that is increasingly difficult to replicate. The approved dock further enhances the property's lifestyle, offering direct access to the river while preserving the property's quiet, protected character. Designed with intention and restraint, Villa Measured achieves a rare balance—architecturally significant yet comfortably livable, substantial without excess. Inspired by the Musée Rodin in Paris, this Neoclassical residence was constructed on 35–50-foot pilings with load-bearing masonry walls, Ludowici terracotta roof tiles, precast concrete floor panels, stone balusters, and Medici yellow stucco. An aggregate stone and concrete drive leads to the residence and its three-car garage, reinforcing both arrival and functionality. Inside, a terra-cotta tiled foyer framed by limestone columns creates a direct sightline through the home to the marsh and river beyond. Twelve-foot ceilings, Ron Batton custom millwork, copper detailing, and full lightning protection reflect the depth of craftsmanship throughout. Living spaces flow seamlessly indoors and out. Upper and lower loggias overlook a vanishing-edge pool and spa, offering multiple vantage points to enjoy the surrounding landscape. Formal living and dining rooms open to a great room connected to the kitchen and vaulted breakfast room, creating a layout that supports both everyday living and entertaining. Four fireplaces—three interior and one wood-burning fireplace in the loggia—anchor gathering spaces, while two custom fire sculptures by London artist Cathy Burkman add warmth, light, and subtle movement. The south primary wing provides privacy within the home, featuring a dedicated study, dual dressing rooms, an exercise room, and double doors opening to a limestone terrace overlooking the marsh. The second level includes five bedrooms and two limestone terraces separated by the Marsh Room, along with approximately 1,100 square feet of additional guest accommodations accessible from both the main and second floors. A tennis rebound court and a finished floor elevation of 16½ feet complete the estate. With gated access, 24-hour security, a rare .86-acre deep-water setting, an approved dock, and a residence scaled for elegant daily living, Villa Measured stands among the most private and thoughtfully proportioned estates on Sea Island.
