Property Description
100 East Putnam Avenue, Apartment 301 -- Brand-New Luxury 2-Bedroom Rental in Cos Cob, Greenwich A new standard for rental living has arrived in Cos Cob. Apartment 301 is a sun-filled, brand-new two-bedroom residence at 100 East Putnam Avenue -- a rare chance to lease luxury new construction in a town where it almost never comes to market. An open-plan layout flows from a generous living and dining space into a designer kitchen, wide-plank flooring throughout, oversized windows with multiple exposures, and integrated smart-home technology for lighting, climate, and entry. The primary suite offers a spa-inspired bath; the second bedroom is well-suited to a guest room, nursery, or home office. The building delivers what you'd expect at this level: secure smart-building access, an expansive landscaped rooftop terrace, covered and uncovered on-site parking, and dedicated storage lockers. The location is the rest of the story. You're along the heart of Cos Cob's main corridor, moments from the town's best restaurants and boutiques, and just a 10-minute walk to the Cos Cob train station -- Grand Central in approximately 44 minutes, Stamford in 12. Greenwich Country Day School's Old Church Road campus is a short walk; the Stanwich campus is a 7-minute drive. Weekends mean Cos Cob Park, the Greenwich Botanical Center, and the quiet sophistication of this stretch of Connecticut.
