Steeped in timeless elegance, this stately 1803 brick Federal stands as a landmark of historic grandeur in Charlestown. A commanding foyer with a sweeping staircase introduces a versatile layout. The main level features a sophisticated living room with a custom built-in bookcase fireplace insert, a convenient bedroom with bespoke built-in, a full bath, an expansive kitchen, and a laundry room. Upstairs, discover a serene primary suite with his-and-hers closets, two additional bedrooms, and a second full bath. Premium upgrades include a Thermo Pride furnace, Rinnai on-demand hotwater, a newer roof, and Harvey vinyl replacement windows throughout. A major asset is the private 1BR accessory apartment with a Rinnai heater--ideal for lucrative rental income. Beyond that, a sprawling bonus space offers a spectacular venue to entertain, a premier home business setting, or a potential efficiency unit. The level, just under an acre parcel features a private, fenced sanctuary with an intimate patio, plus a classic detached barn. Public water/sewer. A rare opportunity to own a peice of history with modern versatility!
