Charles Kirby, the architect of the original Boston Public Library, built the two distinctive five-story residences at 13 & 15 Marlborough Street in the French-inspired Brick Academic style in 1864.
Keeping with the elegant tradition first established by Mr. Kirby, Stonegate, in collaboration with Ahern-Schopfer and Associates Architects, redesigned these two historic structures into one single building in 2004.
