Built in 1872 by the renowned firm Sturgis and Brigham, 86 Marlborough Street is a true Boston architectural gem. Located on the second and third floor of this extra wide townhouse, this 3 bedroom, 3 full bath residence 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. Centrally located Chef’s kitchen with custom cabinetry, granite countertops and high-end appliances opens to the formal fireplaced living room. Three oversized bay windows flanked by custom bookshelves and window seats look out upon tree lined Marlborough Street. Primary bedroom with ensuite bath and ample storage resides on the upper level of this duplex with a second, sun filled bedroom with access to a private patio. Complete with one off street parking space, this is a rare opportunity to own a historically significant home in Back Bay.
