** Open House Saturday 5/22 & Sunday 5/23, 1–3PM** Welcome to 20 Grouse Run in Pelham’s prestigious Garland Woods. This 4+ bedroom, 4.5 bath estate spans three finished levels, offering privacy and versatility with dual gourmet kitchens and multiple private suites. Hardwood floors run throughout the sun-filled interior, where expansive windows frame serene, protected woodland views. Abutting conservation land that cannot be built on, the property offers exceptional privacy and abundant wildlife. The land behind the home is not marshland, but preserved forest with a town-required water reservoir, ensuring a natural setting and long-term protection. The chef’s kitchen features premium appliances and opens to a private deck. The primary suite offers a spa-like bath with soaking tub, tiled shower, dual vanities, and walk-in closet. A second private suite, two additional bedrooms, full bath, and ~400 sq ft unfinished bonus space complete the upper level. The walkout lower level includes 9-ft ceilings, a full kitchen, two bonus rooms, and a private bath—ideal for guests or extended living. Professionally landscaped patio with propane fireplace overlooks tranquil conservation land. Convenient to golf, shopping, dining, and major routes, with Boston under 45 minutes away. Set on over half an acre, this is a rare opportunity in one of Pelham’s most desirable neighborhoods.
