86 Marlborough Street is truly an architectural gem, designed in 1872 by the renowned firm Sturgis and Brigham. This 3-bedroom, 3 full bathroom duplex residence has been carefully renovated and has maintained its historic grandeur, including the original walnut-paneled library highlighted by rare friezes by John Moyr Smith, fifteenth century tiles from a Spanish convent, custom stained-glass and sculptural roundels. The formal fireplaced living room is grand in scale and overlooks tree-lined Marlborough St from three oversized bay windows flanked by custom bookshelves and window seats. Centrally located Chef’s kitchen with custom cabinetry, granite countertops and high-end appliances. On the upper level, the fireplaced master bedroom offers ample storage and en suite bath and the second, sun-filled bedroom has an additional sitting room and access to the private deck. Complete with one parking space, this historically significant home offers something special for the discerning buyer.
