Chalet d'Amour You've never seen a house like this. An architecturally crafted contemporary on 2.32 private acres. Soaring vaulted ceilings, two stone fireplaces, walls of glass, and light that pours in from every angle. First floor primary suite with cathedral ceiling, dual baths, dual walk-in closets and a grand whirlpool tub beneath peaked windows. Three more bedrooms up, all en suite, one with a sauna shower. Open kitchen flows to living and dining. Expansive deck overlooking a completely private yard. Full basement. Three-car garage. North Mianus, Eastern, Greenwich High. With sky in every direction, you'd swear 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+ acre 3500+ square feet, post-1985 construction, and no wet land sold for less than $3.6 million. The median was $6.5 million. A love letter written in stone, glass, and light -- priced like nothing else in its class.
