About This Home

681 River Road

Chalet d'Amour At $2.65M, you're buying the land. The house comes free. Every comparable Greenwich lot -- same town, same schools, 2+ acres -- is offered for more than this asking price, with no house on it at all. So the 3,826 sq ft, architect-designed contemporary that comes with this land? Effectively free. And the floor under that number is something you can verify yourself in five minutes. Run these filters on Zillow: single-family houses, 3,500+ sq ft, 2+ acres, built 1985 or later, sold in the last 12 months. Fifty-five homes. Not one sold below $3.6 million. The median was roughly $7.5 million. (Zillow flags one apparent exception, 43 Hunting Ridge Rd -- but it has just 3,262 sq ft above grade, the rest finished basement, and sits on regulated wetlands.) You're at $2.65M - -- roughly a third of the median, and nearly a million below the cheapest comparable sale in a year. And this is no teardown. Across from Mianus River Park, Chalet d'Amour is an architecturally crafted contemporary unlike anything else on the market: soaring vaulted ceilings, two dramatic stone fireplaces, walls of glass, and light pouring in from every direction. The first-floor primary suite features cathedral ceilings, dual baths, dual walk-in closets, and a grand whirlpool tub beneath peaked windows. Upstairs are three additional en-suite bedrooms, including one with a sauna shower. Five full baths and one half bath throughout. The open kitchen flows into expansive living and dining spaces. A massive deck overlooks a completely private backyard, while the front approach is equally secluded by trees and sky. 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 from town, train, and downtown Greenwich. A rare case where the land alone justifies the price -- and the house is the part you'll fall in love with. Come see it before someone else does the math.
