About this home

Overlooking John Harvard Mall in Charlestown’s historic gaslight district, this handsome, 5+BR/4.5BA, bow front brick townhome, offers 4,000sf of living space and two covered parking spaces. Built circa 1875, the home was rebuilt from the brick façade inward in 2009/10, with all-new framing and major systems, then thoughtfully reimagined in 2024/25 for modern family living. The main level is open and filled with light, with living, dining, and kitchen spaces flowing together beneath crown molding and custom millwork. A gas fireplace with porcelain surround anchors the living area, and a multi-zone sound system carries music throughout. The chef’s kitchen centers on a large marble-topped island and is equipped with a new Thermador six-burner range with grill and double ovens, plus a Sub-Zero refrigerator. Oversized windows and skylights brighten the space, and a French door opens to a private side porch for outdoor dining and grilling. A powder room services this level. The entire second floor is reserved for the primary suite, w/dual walk-in closets and a spa-style bath featuring a freestanding soaking tub, double vanity, and oversized walk-in shower. The third-floor features two generous bedrooms w/dual custom closets; a dedicated home office, full bath, and laundry center. The fourth-floor adds a custom built-in library or study and guest suite. Above it all, the roof deck offers 360-degree views of Boston Harbor and the city skyline. The lower provides versatile living space: a media room w/wet bar and EuroCave wine refrigerator, a gym or au pair suite, an oversized mudroom w/heated floor, abundant storage, and second washer/dryer. A 2-car covered driveway is just off the mudroom. Historic character, modern systems, and a coveted location make this a turnkey Charlestown home.
