Description
Chalet d'Amour This home is priced at least a cool $1 million below the floor for comparable Greenwich houses - and below what the empty land alone would cost. So the 3,826-square-foot, architect-designed contemporary? Effectively free. Both claims are easy to check. The land: every comparable Greenwich lot - same town, same schools, two-plus acres - is offered for more than the asking price here, with no house on it at all. The sales: 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, and the median was roughly $7.5 million. (Zillow flags one apparent exception, 43 Hunting Ridge Rd, but it has only 3,262 sq ft above grade - the rest is finished basement - and sits on regulated wetlands.) This home sits at least a cool $1 million below that floor, and roughly a third of the median. 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, three more en-suite bedrooms - one with a steam shower - plus generous closets throughout. Five full baths and one half bath in all. 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, a three-car garage, and a full unfinished attic - storage and room to expand throughout. 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.
