Mastlands, named for the towering Eastern white pines once used as ship masts, is a historic Cornish Art Colony estate nestled among trees, farmland, and exquisite gardens. Once the summer home of Dr. Arthur Nichols and his family, it carries a rich legacy, with his daughter, Rose Nichols - a prominent landscape architect - designing the walled garden off the piazza, inspired by her uncle Augustus Saint-Gaudens and architect Charles Platt. The estate's 24 acres feature revived gardens, seasonal blooms, restored fountains, and peaceful retreats like Pine Tree Alley and a firepit. The property offers great outdoor opportunities, with access to a nearby Class 4 road connecting to the scenic River Road, ideal for walks, and additional paths around the cornfields for leisurely strolls. The grand living spaces featuring high ceilings and intricate moldings, including a ballroom wing with elements salvaged from a European chateau, combine historic charm with modern comforts and is crafted for sharing with loved ones. A versatile one-bedroom apartment offers independent living or rental potential, making Mastlands a perfect home for those who cherish history and seek to continue its stewardship. Showings begin 9/3.
