ADDITIONAL INFORMATION

A rare and magnificent architectural offering designed by award-winning architect Paul Haigh, where sophisticated simplicity meets the quiet poetry of Bauhaus influence. Set along the serene Mianus River, this home is a masterful composition of nature, light, and form-where every space is intentionally designed to engage with its surroundings. From the moment you enter the oversized foyer crowned by a striking cupola, there is an immediate sense of volume, light, and quiet drama. This architectural introduction unfolds into a home that is both expansive and deeply connected to nature. Walls of glass frame ever-changing river views, while the great room-with its soaring vaulted ceiling, white brick fireplace, and curated built-ins-offers a balance of openness and intimacy. Light moves effortlessly throughout the day, casting warmth across rich hardwood floors and transforming each window into a living work of art. The kitchen is refined and purposeful, with clean lines, natural materials, and a generous central island-all surrounded by soft, ambient light. It is a space equally suited for quiet mornings or gathering with ease. Just beyond, a screened-in porch floats above the river, offering a serene vantage point for coffee at sunrise or long, lingering evenings immersed in the sounds of nature. There are four bedrooms and baths, each thoughtfully composed with a palette of stone, glass, and warm earth tones. The primary suite offers a peaceful retreat with tranquil water views, while the primary bath becomes an architectural sanctuary, featuring a vaulted ceiling, deep soaking tub, glass-enclosed shower, and dual vanities-designed to evoke a spa-like experience of calm and restoration. The lower level continues the home's connection to light and landscape, with oversized windows, a fireplace, and direct access to an expansive flagstone terrace. An original kitchen and abundant storage provide exceptional flexibility, making this level ideal for an in-law suite, guest quarters, or extended living space. Outdoors, the property unfolds organically toward the river. Stone pathways wind through layered plantings and natural landscaping, revealing intimate seating areas and quiet moments at every turn. At the water's edge, a private dock and kayak invite a lifestyle rarely found-morning paddles, afternoon reflections, and evenings defined by stillness and beauty. This is more than a home-it is a living, breathing work of art. A place where architecture and nature exist in perfect harmony, offering a lifestyle of rare tranquility and timeless design.

ADDITIONAL INFORMATION

Chalet d'Amour You've never seen a house like this. An architecturally crafted contemporary on 2.32 private acres across from Mianus River Park. Soaring vaulted ceilings, two stone fireplaces, walls of glass, and light that pours in from every angle. A first-floor primary suite with cathedral ceiling, dual baths, dual walk-in closets, and a grand whirlpool tub beneath peaked windows. Three more bedrooms upstairs, all en suite -- one with a sauna shower. Five full baths and a half bath throughout. Open kitchen flows to living and dining. An expansive deck overlooks a completely private backyard -- and the front yard is just as secluded. Full basement. Three-car garage. Room to do anything. North Mianus, Eastern, Greenwich High. With sky in every direction, you'd swear you were some you were somewhere in the Alps -- not minutes to town and train. You may never see a house like this again. In all of 2025, not a single home in Greenwich with 2+ acres, 3,500+ square feet, post-1985 construction, and no wetland sold for less than $3.6 million. The median was $6.5 million. At $2.75M, you're still $850,000 below that floor -- enough to redo the kitchen, the roof, the deck, whatever you want, and still pay less than anyone else did in 2025. A love letter written in stone, glass, and light -- yours to make perfect.
