Tranquil & Private Nature Sanctuary 4.85 Acres with a midcentury modern main house and spacious carriage house. A rare and extraordinary opportunity to own an exceptional estate in the heart of NW Greenwich, featuring TWO FULLY RENOVATED HOMES on a serene private lane off the prestigious John Street. With breathtaking park-like grounds, year-round flowing water, orchards, a stocked fishing pond, and direct trail access to the Greenwich GRTA Riding Trails & Greenwich Audubon, this property is a world unto itself — yet minutes from NYC, Downtown Greenwich, Westchester Airport, CT Merrit prkwy & NY Routes 684 and 35. *MAIN HOUSE | 7,700 SqFt | 6 Bedrooms | 4.5 Baths* Modern Architectural Masterpiece designed by a renowned architect Warren Plattner, the founder of 'sensuous modernism'. Enjoy grand entertaining, multigenerational living, and everyday comfort. The open-concept layout features dramatic floor-to-ceiling marble and stone fireplaces, enormous windows overlooking the stunning grounds, and bedroom wings thoughtfully positioned across two floors — each with its own Kitchen and Family Room. The top-floor Primary Suite Wing is a retreat unto itself, featuring a private sitting room, dual bay windows, custom built-in closets, and spa bath with a large sauna, jetted tub, and a dramatic backlit Cristallo marble and onyx rainfall shower with body jets — all finished in warm golden honey onyx. A makeup and hairdressing alcove plus dressing closets completes the suite. An additional bedroom suite sits on the opposite top-floor wing with generous bay, fireplace, enormous bay windows and gorgeous eastern morning light. On the first floor, TWO BEDROOM WINGS offer flexibility and privacy. The west wing has three bedrooms, a small office, and two bedrooms with sliders opening directly to a Rose Garden Bluestone Terrace overlooking the pond. The south wing features two oversized bedrooms — fall asleep to the gentle sound of waterfalls from the stream below — plus a large Rec Room and direct access to the apple and pear orchards. Each first-floor wing has its own marble bathroom. The 5,500 SqFt Pool Deck is nothing short of spectacular, with a full Serving Kitchen, Living Room Cabana, and fruit orchards on both sides — including peach, cherry, apple, and pear — plus a terrific hill for sledding and snowboarding. The property also features a gazebo overlooking the stocked fishing pond, three bridges over the stream, a newly redone shed, and ample space for horses. The rear of the property connects directly to riding and walking trails. Systems throughout are new and efficient: 6 HVAC zones via new heat pump systems, 3 new water heaters & smart thermostats. **SECOND HOME (Carriage House) | 3,600 SqFt | 3 Bedrooms | 2 Baths | Six-Car Heated Garage** Privately positioned for maximum separation from the main house, this stunning carriage house offers an open-concept second floor flooded with natural light. Layout includes a dining room, living room, full kitchen, and a Primary Bedroom Suite with a gorgeous bath. A large Ipê wood deck overlooks the western side of the property — perfect for sunset views and stargazing. The third floor adds two additional bedrooms, a family room, and a marble bathroom. One garage bay offers direct interior access to the carriage house, which also has its own full laundry room & ample storage. A newly installed multi-zoned heat pump system plus oil hot water heat serves the second floor and garages. *Excellent Investment Property* Permits for Accessory Dwelling Units (ADUs) have not been granted in Greenwich since 1985 — making a legal two-home estate like this extraordinarily rare and highly valuable. Both the Main House and Carriage House have substantial rental history, offering compelling income potential. Plus multigenerational flexibility & expansion opportunity. *Qualified buyers only.
