The Beaux-Arts mansion, designed by Carrère & Hastings,[1] was at 2 East 70th Street, at the southeastern corner with Fifth Avenue.

When the house was completed, it had a grass planting strip on Fifth Avenue, with two plane trees.

The New York Times described it in 1915 as "an excellent example of good architectural taste combined with the luxuries and comforts of a Fifth Avenue home.

[9][10] In September 1914, the buyer was reported as C. Ledyard Blair,[2][8][11] a banker and Governor of the New York Stock Exchange.

[14] By 1925, Blair was meeting with real estate developer Anthony Campagna to sell his mansion.

[17] He tore down the house in late 1926 and early 1927, redeveloping the site with a new 11-story apartment building designed by Rosario Candela.
