About This Home

Welcome to Martins Pond Farm—an enchanting 12-acre retreat where timeless country charm meets refined modern living, just minutes from Groton’s vibrant center and the Ayer commuter rail into Boston. Its sustainably and meticulously renovated 1940s farmhouse offers warm, inviting light-filled spaces, with each window framing a pastoral tableau of prolific gardens, rolling meadows, a tranquil pond, and berry-laden paths, bordered by secret marshes where great blue herons thrive and hickory dotted woodlands where wildlife wander. The iconic red pole barn--with water and electricity--is ready for chickens, horses, hobby farming, or simply as a picturesque landmark of your sanctuary. The home's thoughtfully curated updates--from Andersen windows and a handcrafted maple kitchen to spa-inspired baths and energy-efficient systems--blend authentic character with contemporary country chic. Here, you're invited to embrace a lifestyle of peace, privacy and endless wonder.
