Introducing the Ayer Mansion, widely regarded as one of the most stunning and distinctive addresses on Commonwealth Avenue in Back Bay. A National Historic Landmark, the Ayer Mansion is the last surviving example of a complete residential commission by the famed American artist, designer, and craftsman Louis Comfort Tiffany. Tiffany combined exotic architectural style with masterful design elements to create a museum-quality masterpiece that is just as unique now as it was at its unveiling at the turn of the 20th century. Soaring arched ceilings, shimmering opalescent glass and mosaics, oversized bow-front windows with stained-glass panels, intricate, handcrafted moldings and woodwork, a grand elliptical staircase and a striking mosaic trompe-l’œil Greek temple revealed through a proscenium arch are just some of the many highlights of this magnificent property. This is a once-in-a-lifetime opportunity to make this outstanding residence of timeless artistic significance home.
