About This Home

This one of a kind property is comprised of two unique lots. On .72 acres in one of Old Greenwich's most coveted enclaves, 21 Keofferam Road offers the perfect blend of coastal charm and timeless luxury. Just eight houses from the water and less than half a mile to both Tod's Point Beach and the vibrant Old Greenwich Village, this address captures the very essence of seaside living. With its rare oversized lot, the property provides an exceptional canvas to design and build a legacy estate where new memories can be created for generations to come. Expansive grounds offer privacy and space, while the shoreline's salty breezes and the village's boutiques and cafes are only moments away. This is more than a home—it's a lifestyle. Mornings at the beach, afternoons on the water, and evenings spent in the village bring an effortless rhythm to life in Old Greenwich. 21 Keofferam is an opportunity to put down roots in the quintessential coastal location.
