Residences In 1916, Auchincloss built Builtover, today known as the
Charles Crooke Auchincloss House, a 25-room Georgian Revival mansion built by the firm of
Peabody, Wilson & Brown in
Roslyn, New York. The
Olmstead Brothers, the same firm that designed
Central Park, were the architects for the grounds in 1917. In 1925, burglars entered their Roslyn home during a storm and "stole Oriental rugs, tapestries and household ornaments valued at more than $10,000". His wife became a well known hostess and member of society. In 1946, they sold Builtover to Dr. Daniel Twohig who renamed the mansion My Beloved. The
Long Island Expressway was later built on the other side of the property. Auchincloss took over 120
East 70th Street from his brother, Edgar, who lived there with his wife and family, together with their brothers Gordon and Samuel, who also lived there with their wives. On October 19, 1930,
The New York Times announced Charles' plans to replace the 70th Street house with "a five-story, brick, marble and granite trim" residence designed by Edward S. Hewitt. The home was completed a year later in the stylized neo-Georgian design and sat on a street that
Fortune Magazine described nine-years later as "the most beautiful residential block" in the city. ==References==
