Historic Tiffany-Designed Ayer Mansion Listed for $11.5 Million in Boston's Back BaySource: Google Street View

The Boston real estate scene is witnessing a prominent listing with the Ayer Mansion, a historic landmark and the only remaining residential project designed by the illustrious Louis Comfort Tiffany, hitting the market for $11.5 million. Found at 395 Commonwealth Ave. in Back Bay, the approximately 15,000 square foot mansion embodies the grandeur of a bygone era, showcasing Tiffany's daring use of color and materials throughout its 23 bedrooms and 12 baths, as reported by The Boston Globe.

Originally commissioned by the influential textile magnate Frederick Ayer, the residence signifies a rich history, and after Ayer's death in 1918, it served diverse roles including office space, a medical clinic, even hosting a female students' dormitory until December 2021 when 395-399 Commonwealth Avenue LLC made an off-the-market purchase of the property; however, the initial listing last May stood at a loftier $17 million but saw a significant drop to $14,995,000 in November before the listing was withdrawn in April 2024, only to re-emerge this February, as described by The Boston Globe.

Beyond the historical significance, the estate's intricate details shine with shimmering opalescent glass, mosaics, a mosaic trompe-l’œil Greek temple, and a grand elliptical staircase that hail from Tiffany's exotic architectural style—details which are underscored by Zillow, calling it a "museum-quality masterpiece". The mansion is not only a reflection of Tiffany's artistry, but a contributor to Boston's architectural landscape, featuring a granite facade with mosaic panels and a dazzling array of stained-glass work.

Located centrally in Back Bay, the opulent townhouse benefits from panoramic rooftop views, adds convenience with four parking spaces, and is heralded for its proximity to Newbury Street, Harvard Bridge, and Fenway amidst the Boston cityscape; however, prospective buyers should note the National Historic Landmark status, which while affirming the mansion's heritage and prestige could pose challenges for future alterations or renovations needed for modern living although it has undergone restorative renovations and is "widely regarded as one of the most stunning and distinctive addresses on Commonwealth Avenue in Back Bay," according to the listing by Tracy Campion of Campion & Company Fine Homes Real Estate, which was mentioned in The Boston Globe.
