Coming Soon! Campion and Company is pleased to introduce the Thayer Mansion at 305 Commonwealth Avenue, the epitome of luxury living in the heart of Boston's iconic Back Bay. Located on the sun-drenched side of Commonwealth Avenue, this former single family mansion has been converted into four distinctive residences for your consideration.
Designed in 1884 by Peabody and Stearns, a premier architectural firm of the late 19th and early 20th centuries, this Gilded Age building has undergone a painstaking restoration. Under Hexagon Properties’ watchful eye, the four residences now seamlessly combine the building’s rich history with the finest modern finishes, including custom gourmet kitchens, marble bathrooms, the newest technologies, and the addition of private outdoor space and a parking garage. The architectural details within the residences, such as hand-carved decorative mouldings, ornate ceilings, coffered beams, and quarter sawn oak floors, have been meticulously preserved and enhanced to provide the perfect balance of old and new.
