About This Home

20 Marianne Road

New construction and ready for 2026! On a coveted Darien cul-de-sac, this modern colonial boasts 6500sf of elegance and comfort. Step through the welcoming foyer, complete with a coat room and powder room, and into a spacious, light-flooded living room, perfect for gatherings that stretch into the evening. The custom kitchen is a true centerpiece, with a grand stone island, Thermador appliances, an oversized range, and abundant cabinetry. Surrounded by windows, the sunlit breakfast room flows effortlessly to the kitchen/great room, where a gas fireplace and beamed ceiling create warmth and character and flow out to an huge deck overlooking 1.2 private acres. A first-floor office with full bath offers flexibility for work, guests, or a quiet retreat. Everyday ease continues with a mudroom, half bath with stunning, floating quartz vanity, and an attached two-car garage. Upstairs, the primary suite is a serene escape with vaulted ceilings, a walk-in closet, and a private balcony overlooking the lush and private yard. Three additional en-suite bedrooms each feature custom walk-in closets, blending function with elegance. The partially finished third floor and lower level invite endless possibilities - a home gym, playroom, creative spaces, etc. This home has privacy and space for all and is only minutes from town, shops, the beach, golf, the train and all amenities. A new home for the new year!
