About this home

Mason House was designed by architects Arthur Rotch and George Thomas Tilden and constructed circa 1883 for Mr. & Mrs. William Powell Mason. Under the stewardship of the Mason’s daughter, Fanny Peabody-Mason, the property developed a rich history. Miss Mason was well known as an active patron of music in the United States and abroad. In 1891, the first of Miss Mason’s regular music salons was inaugurated in the magnificent music room. From 1891 to 1948, Miss Mason played host to many of the world’s greatest musicians, composers, conductors and luminaries. In 1998, the current owners purchased the property and conducted an extensive museum-quality renovation. Today, the residence offers formal reception rooms, a family kitchen and living room, a master suite, nine family/guest bedrooms, 6 bathrooms and au pair suite. The crowning jewel of this residence is the expansive roof terrace with panoramic city views. There is a fabulous walled garden and a heated garage for 5 to 6 cars.
