Nestled on an extraordinarily private 2.33-acre estate in the coveted Winterthur community, this architectural jewel is discreetly positioned in the heart of Sandy Springs--offering a rare convergence of provenance, design pedigree, and resort-caliber grounds. Originally conceived as the personal residence of renowned architect Robert Green, protege and direct understudy of Frank Lloyd Wright, the home has been masterfully reimagined under the direction of acclaimed architect Rodolfo Castro--preserving its midcentury integrity while elevating it to a standard of modern luxury. A gated approach and a long and meandering newly constructed driveway set the tone for the arrival experience, framed by extensive, thoughtfully executed landscape and hardscape design by Bellwether Landscapes. The grounds are nothing short of extraordinary--featuring newly installed stone walls, expansive patios, a courtyard terrace with a statement fireplace, an extended level lawn, and a breathtaking 75-foot heated lap pool that anchors the outdoor living experience. Upon entry through striking steel and glass doors, interiors are immediately illuminated by an oversized skylight, casting natural light across the home's refined architectural lines. The fully renovated kitchen is appointed with custom solid walnut cabinetry, Calacatta Gold countertops, and a suite of professional-grade appliances. Seamlessly integrated, the kitchen flows into an inviting breakfast room, a fireside keeping room, and an adjoining office. Four generously proportioned bedrooms reside on the main floor, each served by two impeccably renovated full baths. A dramatic stair hall descends to the terrace level, where the home's architectural character is on full display. Here, original wood paneling has been meticulously preserved, showcased in a vintage wet bar, a raised living area, and a striking sunken family room centered around a stone fireplace with a built-in sectional--an iconic midcentury design moment. The terrace level also hosts a richly paneled fireside den, ideal as a private study or retreat, complete with a newly installed sauna. Tucked away for ultimate privacy, the primary suite is a true sanctuary--featuring dual walk-in closets and a spa-caliber bath with dual vanities, a freestanding soaking tub, and a frameless glass shower, all executed with a refined, contemporary sensibility. Every principal room along the rear elevation opens to the exceptional outdoor environment, blurring the line between interior and exterior living. Expansive patios provide ample space for dining and lounging, while the manicured lawn offers a rare, usable expanse ideal for recreation. With five bedrooms, three full and one half baths, approximately 4,500 square feet, and a three-car garage, this residence represents a once-in-a-generation opportunity to own one of metro Atlanta's most architecturally significant midcentury homes--thoughtfully restored, meticulously curated, and impossibly private.
