The Adelaide L. T. Douglas House is a historic building located at 57 Park Avenue between East 37th and 38th streets in the Murray Hill neighborhood of Manhattan in New York City.

The Adelaide L. T. Douglas House is located at 57 Park Avenue, on the east side of the street, in the Murray Hill neighborhood of Manhattan in New York City.

[5] Nearby buildings include Our Saviour Roman Catholic Church to the north, Scandinavia House – The Nordic Center in America to the west, and the Union League Club to the south.

[5] The site at 57 Park Avenue was previously occupied by a four-story residence owned by John J. Murphy, which was severely damaged on March 21, 1902, during a tunnel cave-in caused during construction of the first New York City Subway line.

[6][7][8] As part of a settlement to avoid a lengthy court case,[9] Murphy's house, along with some of the other buildings that had been damaged on the east side of the block, were purchased by the Interborough Rapid Transit Company (IRT) in April 1902 and then demolished.

[12] Prominent New York socialite Mrs. Adelaide L. Douglas bought the site at 57 Park Avenue in 1909, intending to develop a new residence.

[4][40] Similar to other residences designed by Trumbauer, the Adelaide L. T. Douglas House was patterned in the Louis XVI style of eighteenth-century France and has limestone and granite cladding.

[18][41] The building's façade is divided vertically into three bays and recessed behind an areaway at ground level, which in turn is surrounded by a wrought-iron fence.

[33] While numerous changes have been made to the interior of the building, such as the redesigning of rooms to accommodate additional space for offices, the exterior of the structure has remained almost entirely intact.
