There are homes that offer more space-and then there are homes designed to elevate the way you live. Welcome to 12 Alexander Drive, a stunning Colonial set on a beautifully manicured one-acre lot in a private, peaceful Londonderry, New Hampshire neighborhood. From the maintenance-free farmer's porch, step inside to nine-foot ceilings, gleaming hardwood floors, and sun-filled living spaces. A custom sitting area creates a welcoming first impression, while the open-concept kitchen, dining, and fireplaced living area becomes the heart of the home, with granite counters, stainless steel appliances, a center island, and effortless flow to the rear deck and backyard. Upstairs, the primary suite feels like a private retreat with an expansive bedroom, walk-in closet, spa-inspired bath with tiled shower and soaking tub, plus a flexible bonus space ideal for an office, dressing room, nursery, or fitness area. Three additional bedrooms, a full bath, hardwood flooring, and second-floor laundry complete the level. The daylight walkout lower level sets this home apart, offering a true in-law-style living environment with a full quartz kitchen, generous cabinetry and counter space, living room, spacious bedroom with double closets, luxury bath with marble-tiled shower and soaking tub, separate laundry hookup, and direct patio access. Designed to adapt beautifully to every stage of life, this is a home where comfort, quality, and versatility come together.
