128 Beacon Street was designed by architect George Snell and built in 1860, one of three contiguous houses (126-128-130 Beacon). Originally, all three houses had front stairs and entrances on the first floor; 126 and 128 Beacon were remodeled, probably in the early 1900s, so that the entrances were lowered to street level. By 1933, the house had been acquired by the Emerson College of Oratory and combined with 130 Beacon, which they also owned. In 1943, the College acquired 126 Beacon and combined it with 128-130 Beacon. Emerson College continued to own 126-128-130 Beacon until 2003. In June of 2003, Rockwood/Beal I, LLC, formed by The Beal Companies LLP real estate developers, purchased 126-128-130 Beacon from Emerson College. In September of 2005, it converted the houses into eleven condominiums.
