Commissioned by printing magnate Jonathan Bulkley in 1911, this James Gamble Rogers-designed residence is a stately home in the Modern Renaissance style. At once the site of many a lively high-society reception, the building became the home of the Swedish government's Consul General in 1946. As of 2011, the building was home to the Swedish Ambassador to the United Nations.

The brief home of the "ambitious" Ms. Jessie A. Robbins and Henry T. Sloane was designed by Carrere & Hastings for the new couple and completed in 1896. By the time the couple moved into the French limestone mansion, Ms. Robbins had "discovered" Perry Belmont, son of politician August Belmont, and was divorced from Sloane in 1899. The grand marble residence was then rented to Joseph Pulitzer and family—including his 17 servants—and was purchased by a James Stillman in 1901, who occupied the site until his 1918 death. Following the death of it's next proprietor, carpet magnate John Sanford, the home became the site of several institutions, including the Lycee Francais which adjoined it with the neighboring French-style mansion. In 2010, the massive building was purchased by the emir of Qatar for $26 million.

In 1880, railroad and banking royalty Henry Cook bought the whole block between 78th and 79th streets, Fifth to Madison avenues for which he paid $500,000. Cook commissioned a grand mansion, his second on the block, from Stanford White of well-known firm McKim, Mead & White in which he sought to display his prized art collection. White's Italian Renaissance-style creation was never lived in by Cook, who died mid-construction. Cook's daughter inherited the house and sold it to Jospeh Fuller Feder in the early 1900's. The Church of Latter Day Saints purchased the impressive property and used it as a space to school missionaries in the art of conversion. In 2011, the 15,000-square-foot home was put on the market for $49 million, and sold in 2012 for $42 million.

Designed to imitate the arresting white facade of William K. Vanderbilt's Fifth Avenue home, railroad investor Isaac Fletcher hired C.P.H. Gilbert in 1898 to design his French Gothic limestone mansion. The asymmetrical manse was occupied by Fletcher until his 1917 death. In his will, Fletcher donated his home as well as 251 art objects from his collection to the Metropolitan Museum of Art. The following year, the museum sold the home in order to fund a collection in Fletcher's name to Sinclair Oil founder Harry Sinclair who in turn sold it to the last surviving descendant of Peter Stuyvesant to carry the surname, who moved into the home and lead a reclusive life with his sister. After Stuyvesant's death, the home was purchased in 1955 by the Ukrainian Institute of America, which maintains the home as open to the public.

Leather merchant and Special Deputy Police Commissioner Julien Stevens Ulman bought this building from an early developer, who commissioned the architectural firm of Buchman & Fox to bring the five-story limestone neo-Renaissance home to fruition. Despite the historic facade, the 34-room home's interiors were fully modern at the time with elevators, electric lights, and steam radiators. Years after Ulman's 1920 death, his widow sold the manse to Hagop Kevorkian, an Armenian-born archaeologist, art connoisseur and collector. The Bentley School bought the building in 1941 for $125,000 to accommodate it's growing student-body, but sold it in 1946, when it was converted into an apartment building with two units per floor. In 1964, the second floor was converted into the modern art-touting Bykert Gallery. Today, the home's largely preserved parlor level is home to Crown, an upscale restaurant operated by John DeLucie.

A modern-looking home at the time of its construction, the 1914 house of Lewis Gouveneur Morris and his distant cousin and wife Alletta Nathalie Lorillard Bailey was constructed following the power-couple-of-antiquitie's union (Morris, the descendant of a Declaration of Independence signer, and Bailey, descendent of colonial leader Robert Livingston). The home was designed by Ernest Flagg in the Georgian and Federal styles, and included gas and electric fixtures. The home is currently owned by the Avi Chai foundation, which seeks to support "alienated and assimilated Jews worldwide." While the home takes the more stately Park Avenue address, its entrance is on 85th Street.

This mansion was gifted to John Henry Hammond and his wife Emily Vanderbilt Sloane upon their marriage by the bride's father, William D. Sloane, who purchased the land from Andrew Carnegie for the execution of a Carrere & Hastings-designed Renaissance-style mansion. Completed in 1903, the grand home had a second-floor ballroom and a fifth-floor squash court used more for roller skating in the childrens' older days. The Hammonds lived in the home for 44 years, where nary a cigarette or sip o' booze was consumed. The house was purchased by an opthalmologist who, just one year after the US-USSR consulate agreement in 1974, sold it to the Soviet Union for $1.6 million. After much turbulence, the Russian consulate finally moved into the building in 1995.

The land on which this stately house sits was purchased from steel tycoon Andrew Carnegie, who snatched up the land surrounding his own house to regulate his neighbors, by carpet magnate William D. Sloane on the occasion of his daughter's marriage to James Abercrombie Burden Jr. Architects Warren and Wetmore, also behind Grand Central Terminal, were commissioned to design the Beaux Arts manse ripe for entertaining. Following Burden's 1932 death, the home was leased with all of its exotic furnishings and artwork to socialite John Jacob Astor VI. In 1938, the widowed Burden sold off the home's interiors and it was sold to the Convent of the Sacred Heart which, along with the neighboring mansion, occupies the site to this day with an all-girls Roman-Catholic school.

Commissioned by banker Francis F. Palmer in 1916, the stately Colonial Revival home that stands today was designed by firm Delano & Aldrich. The home had a large side court that served as a formal garden, but that was not enough for banker George F. Baker Jr., who acquired the home in 1926 and gobbled up an adjacent lot creating frontage of 100 feet down park Avenue and 139 feet down 93rd Street. Baker reenlisted Delano & Aldrich to create a garage with upper-level servants quarters adjoined to the mansion via a "ballroom wing." The main house was purchased from the widowed Mrs. Baker, who had converted the garage's servants quarters into her pied-a-terre, in 1958 by The Synod of Bishops of the Russian Orthodox Church Outside of Russia. The once-elegant garden was converted into a courtyard entrance, and the "ballroom wing" into an assembly hall.
