13 and 15 West 54th Street (also the William Murray Residences) are two commercial buildings in the Midtown Manhattan neighborhood of New York City.

The four-and-a-half-story houses were designed by Henry Janeway Hardenbergh in the Renaissance-inspired style and were constructed between 1896 and 1897 as private residences.

The houses contain a rounded oriel facing 54th Street and a central pair of entrances above the raised basement.

The houses were commissioned for businessman William Murray, who respectively sold 13 and 15 West 54th to Jessie Neilson and James B. Dickson.

[10][11] The houses at 5–15 West 54th Street, all developed in the late 1890s for wealthy clients, were designed as a cohesive grouping, unlike other residences in the neighborhood.

[12] According to The New York Times, the houses form the sole remaining "real strip of mansions" in Midtown Manhattan.

[3][13] The twin houses at 13 and 15 West 54th Street were designed by Henry Janeway Hardenbergh in the Renaissance-inspired style.

On the portion of the stoop wall facing the sidewalk are oval vents with iron grilles, above which are cartouches.

The third-story windows are flanked by vermiculated blocks and topped by lintels with elaborate scrolled keystones.

There are also three windows on the fourth story of each house, as well as a carved plaque at the center of the facade between numbers 15 and 13.

The windows and plaque are flanked by Ionic pilasters with pedestals at the bottom and volutes at the top.

[20] The top two stories of the two townhouses are connected to 20 West 55th Street, a 13-story office building, at their rears.

The University Club, whose construction commenced the same year, was the first structure to be built on the former hospital plot.

[10] Murray conveyed number 13, approximately 275 feet (84 m) west of Fifth Avenue, to Jessie L. Nielson in January 1898.

[31] At the time of the lease, a columnist for the New-York Tribune wrote, "John D. Rockefeller, Jr. certainly has no regard for unlucky thirteen.

"[32] Next door, Murray retained ownership of number 15 until late 1905, when the firm Pease & Elliman sold that house.

[33][34] The buyer was Johnson & Higgins Insurance Company president James B. Dickson,[35][36] who finalized his purchase in January 1906.

[41][42] The plans called for the addition of the fifth-story attic, a sun parlor at the rear, and a new window and elevator at a cost of $10,000.

[17] The Rockefellers leased number 13 to Robert Abel-Smith in 1932,[55] and the surgeon Charles W. Depping had an office there by 1936.

Rockefeller wished to renovate a portion of the townhouse and anticipated expanding it with the growth of his collection.

[64] Rockefeller retained the office throughout the rest of his life, even when he served as the Vice President of the United States from 1974 to 1977.

A little more than two years after leaving the vice presidency, Rockefeller suffered from a heart attack and died at his 54th Street office in January 1979.

[69] Though the Museum of Modern Art was occupying the houses while its own structure was being rebuilt, there were rumors that the four properties would be demolished to make way for an office building.

[24][25] Under the arrangement, Feldman Brothers would complete the office building's construction and renovate the two houses, which were being refurbished by Haines Lundberg Waehler.

[1] The next occupant of the houses, Danish bank Unibank, would leave several stories unused for several months on end before it moved out by 2000.
