It features an advanced rainwater collection system and stays naturally cool with roof outlets and north-facing walls. Awarded historic designation in 2011, this waterfront retreat masterfully blends Seibert’s vision with modern, design-forward living, all in harmony with its lush subtropical setting. Set on nearly an acre with 135 feet along Heron Lagoon, the 4,006-square-foot home was meticulously renovated to enhance flow and entertaining. The minimalist yet inviting interior features large-format white tile floors, abundant skylights and seamless transitions between spaces. Clean lines, natural light and a strong connection to the outdoors define the living experience. The gallery-style foyer serves as a striking entry and an elegant space to showcase the home’s architecture and proficiency. Large solid wood and frosted glass sliding doors reveal a versatile space, currently a lounge but easily converted to an office or private guest room with its walk-in closet, floor-to-ceiling windows, built-in bookcase and separate entrance from the front door. Just beyond the private room and through the gallery, the home unfolds into the expansive family living area. The seating area, great room, and thoughtfully reimagined kitchen are designed for aesthetic appeal and everyday function. Outfitted with a Samsung induction cooktop, built-in oven and refrigerator, as well as an LG microwave, the kitchen’s minimalist composition is enhanced by a walk-in pantry featuring quartz countertops and concealed appliances, creating a seamless, gallery-like feel. A dramatic tiled counter-to-ceiling backsplash encloses an oversized picture view of nature, connecting interior life to the outdoors and beyond. The Florida room, wrapped in retractable glass, offers the ultimate flexibility—fully enclosed for intimate dinners or opened wide for breezy indoor-outdoor entertaining. The primary suite provides a tranquil sanctuary with designated seating, sleeping and dressing areas. The en-suite bath combines clean-lined surfaces with warm wood accents, stone countertops, a soaking tub, and a walk-in shower, creating a spa-like ambiance. Three well-appointed guest bedrooms include two with private courtyards, one features an en-suite bath, while the other two share a beautifully designed full bath. Designed for entertaining, the home’s open gathering spaces flow seamlessly to a striking outdoor setting with a covered kitchen, bar seating, grill, beverage area, spacious lounge and dining zones, and an open-air space for yoga, meditation or evening soirées. True to its roots in the Sarasota School’s philosophy, the feeling of being outside when inside the home is seamless. Native landscaping, shell-inlaid hardscape, and a one-of-a-kind Ipe wood treehouse are thoughtfully designed to withstand the test of time. In the gated Sanderling Club—a private enclave with 24-hour security, a private beach and marina access—The Ness House is a celebration of art, architecture and the Florida lifestyle at its most refined.
