Scheffel Hall at 190 Third Avenue in the Gramercy Park neighborhood of Manhattan, New York City, was built in 1894–1895, and designed by Henry Adams Weber and Hubert Drosser, at a time when the area south of it was known as Kleindeutschland ("Little Germany") due to the large number of German immigrants who lived nearby. The building, which served as a beer hall and restaurant, was modeled after an early 17th-century building in Heidelberg Castle, the "Friedrichsbau", and was named after Joseph Viktor von Scheffel, a German poet and novelist. It later became known as Allaire's, a name still inscribed on the building. The building's style has been described as "German-American eclectic Renaissance Revival".Later, in the late 1920s, the building was used by the German-American Athletic Club. By 1939 it became the German-American Rathskeller, and then Joe King's Rathskeller. O. Henry used Scheffel Hall as the setting for "The Halberdier of the Little Rheinschloss" and wrote some of his stories there. Beginning in the 1970s, it was the home of Fat Tuesday's, a well-known jazz club, and the restaurant Tuesday's, which lasted until the early 21st century. It is currently a yoga and pilates studio. Update: as of late August 2020 the building is for rent. Sal Anthony, who had his movement studio here, has died. This is a glorious example of 19th century architecture. Scheffel Hall was designated a New York City landmark in 1997.

The Stuyvesant Apartments, Stuyvesant Flats, Rutherfurd Stuyvesant Flats or simply The Stuyvesant, was an apartment building located at 142 East 18th Street between Irving Place and Third Avenue in the Gramercy Park neighborhood of Manhattan, New York City. It is considered to be the first apartment building in the city intended for the middle class, who previously were not used to living in apartments, which were initially called "French flats" at the time.Before the Stuyvesant, almost all of the housing in New York City consisted of either tenements or townhouses. The Stuyvesant helped to bridge this gap, satisfying the need for higher density but upscale housing. Rents ranged from $1,000 to $1,800 per year, the rough equivalents in 2015 of approximately $8,000 to $14,000 per year.The Stuyvesant was successful, leading the way for other such buildings to be constructed. In their book New York 1880, Robert A. M. Stern and his co-authors wrote that the Stuyvesant was the "foundation stone" of the movement of the middle-class into apartments.

The St. George or The St. George Residence, now functioning under the name of Hotel 17 is a historic building located at 223–225 East 17th Street, on Stuyvesant Square in Manhattan, New York City.

On August 19, 1989, a large steam explosion in front of a residential building generated a large asbestos-containing steam cloud in the Gramercy Park neighborhood of Manhattan, New York City. Two people – a Con Ed worker and a 3rd floor resident – died instantly and 24 were injured. A third person, another Con Ed worker, died the following day. Two hundred residents were displaced for months while cleanup crews worked to remove asbestos-containing mud from building facades. All apartments were remediated by asbestos workers and tested for airborne asbestos. Workers from Con Ed, the major utility company in the area, were repairing a high pressure steam pipe in front of the building when a 30-inch (76 cm) connecting sleeve burst, releasing hot steam and debris upwards. Laboratory testing afterwards determined that the insulating material contained asbestos, which subsequently led to a large-scale evacuation and cleanup. The release from the explosion, in front of 32 Gramercy Park at the corner of 20th Street and Third Avenue, continued for several hours with debris reaching 18 stories. The pipe was covered with asbestos magnesia block insulation which was pulverized and dispersed with the rising steam cloud. Con Ed initially failed to report that the debris contained asbestos, but after 4 days announced that the 200 pounds of insulation did contain the cancer-causing material. Five years later, when indicted on the same issue, the company pleaded guilty to conspiracy and environmental law violations in Federal District Court in Manhattan for withholding that information. The final remediation and cleanup cost totaled approximately $90 million, making this one of the most expensive asbestos cleanup projects in history.

The Society for the Lying-In Hospital was an American maternity hospital situated at 305 Second Avenue between East 17th and 18th Streets in the Stuyvesant Square neighborhood of Manhattan, New York City. Now known as Rutherford Place, the building was added to the National Register of Historic Places in 1983. Lying-in is an archaic term for childbirth (referring to the month-long bed rest prescribed for postpartum confinement). It was built in 1902 and designed by architect R. H. Robertson in the Renaissance Revival style, with a Palladian crown at the top. Swaddled babies decorate the windows of the 5th floor and the spandrels of the building, which was converted to offices and apartments in 1985 by Beyer Blinder Belle.As the years passed, John Pierpont Morgan, Jr. was concerned about the long-term stability of the hospital his father had so generously provided for. He recruited John D. Rockefeller, Jr.; George F. Baker, Sr.; and George F. Baker, Jr. to join forces in establishing an association with New York Hospital. Upon the subsequent opening of the New York Hospital-Cornell Medical Center in 1932, the Lying-In Hospital moved out of the Second Avenue building. It became the more modern-sounding Obstetrics and Gynecology Department of New York Hospital, which is still part of NewYork–Presbyterian Hospital. This hospital was "said to account for 60 percent of all births in Manhattan." Some of their staff did medical research.
