About this home
Scale, history, and value rarely align like this on the flat of Charlestown. Spanning four levels and 3,360 square feet, this 1880 brick brownstone offers more space, more parking, and more fireplaces than nearly anything else in the neighborhood today, at a price that leaves real room in the budget. The main and upper levels live as a gracious single-family home with an updated kitchen, formal dining room, four fireplaces, and a private deck and patio. A garden-level suite with its own entry adds flexibility as a guest suite or office, plus a clear path to reconfiguring the upper floors into the two-bedroom, single-level layout Charlestown families want. A deeded heated garage plus two more spaces round out a rare three-car footprint near Main Street, the Navy Yard, and the waterfront. A newly improved price on a home with room to make it your own.
