First Church of Christ, Scientist, October, 1928.

The Ardsley, 1931. Completed in 1931 the building remained "The Ardsley," though it was a very different structure. Designed by famed Art Deco architect Emery Roth, the now 22- story building was a Mayan inspired Deco masterpiece. Because of the changes in zoning in 1916, taller buildings were required to include setbacks for increased light and air. Roth took this requirement and ran with, creating ziggurat-like setbacks decorated with Mayan style motifs and executed in black brick on a beige facade. The apartments within were smaller and less extravagant than the ones in the previous building (large rooms but no servants quarters). The exception to this was the triplex on the 21st, 22nd, and 23rd floors. This 11-room suite included 15-foot ceilings and a wood-burning fireplace in every room. Its occupants also had access to a wrap-around terrace on the 21st floor and two terraces on the 22nd floor.

Eldorado Apartments ARCHITECT: Margon & Holder; Emery Roth DATE: 1929-31 STYLE: Art Deco The Eldorado, extending along the entire blockfront of Central Park West between 90th and 9lst Streets, is the northernmost of the four twin-towered apartment houses that give Central Park West its distinctive skyline silhouette. The Eldorado was designed in 1929 by the architectural firm of Margon & Holder with the renowned early 20th-century New York City architect Emery Roth as a consultant. These architects created one of the finest and most dramatically massed Art Deco style residential buildings in New York City.

The Ardsley, 1928. Built in 1900 and designed by George W. Keister, the ten-story apartment building was a grand apartment house. The rounded bays of the Central Park West facade allowed for excellent views of the Park and for ideal cross ventilation. The individual apartments were massive with six to twelve rooms; some apartments had three bathrooms. Other features included private telephones, electric lighting and individual "refrigeration plants." But the gilded, over the top 19th century style of the building was, by the 1920s, passé. The older Victorian style buildings of Central Park West began to be demolished and in their place, sleek Art Deco style buildings were rising.

Using Google Street View if you drop yourself into New York City, there is a very high chance that you will come across scaffolding over sidewalks. Also known as sidewalk sheds, these can be seen all over the five boroughs. Scaffolding has always been there across the entirety of New York City, but we don’t really know why and what is the purpose of scaffolding. Scaffolding in New York City is 400 miles long, which protects pedestrians from falling bricks and provides shelter when it rains. However, scaffolding destroys city landscapes and leads to other safety concerns, especially when walking at night. Some scaffolding covered the buildings over ten years, which also led to the fact that people never actually get a chance to see the entire design of the building. A misconception surrounding these sidewalk sheds is that they are up because of all the constant new developments in the city. The truth is far from this. To understand why almost every street in New York City looks like this we have to go back to 1979 when Grace Gold, a freshman at Barnard College in Columbia University was killed by a falling piece of masonry. The city responded to this by passing Local Law 10 in 1980 which was later amended by Local Law 11 in 1980 which required buildings over six stories tall to have their facades inspected every five years. If they fail inspection, the building owner is required to repair the facade, and in the meantime install a sidewalk shed to protect people from falling debris. The problem is, the law isn’t working as intended. Buildings fail inspection all the time and that is primarily because New York is chock full of buildings whose exterior masonry was done decades if not centuries ago. Repairing the facades of these buildings is very expensive. But here is what isn’t expensive, indefinitely leaving a sidewalk shed up. For most building owners it is cheaper to just leave the shed up, pay the occasional fine, and hope residents don't mind paying $3,000 a month to live in a building they’ve never seen. So that's exactly what they do. That's why a building like 409 Edgecombe Avenue in Harlem has had its sidewalk shed up for over 15 years.

El Dorado Apartments, ca. 1920. The history of the El Dorado Apartments is similar to that of its nearby neighbor The Ardsley. The original El Dorado (seen in this photograph) was an eight-story speculative apartment house completed in 1902. Somewhat similar in design to the original Ardsley, the CPW front of the building had large rounded corners to allow for sweeping views of the park and good cross ventilation. In the 1920s the real estate market on Central Park West boomed and a number of the older apartment houses were demolished and replaced. In 1929 investor Frederick Brown bought the first El Dorado and resold the site to Louis Klosk, a Bronx-based developer. The financial crisis that followed would eventually stall the construction and force Klosk to foreclose. The eventual building, finished late in 1931 under new ownership, was a 30-story, twin tower Art Deco building. Designed by Margon & Holder, and their associate architect Emery Roth (who designed the second Ardsley) the large building has terraced setbacks on the towers topped by abstract geometric spires.

First Church of Christ, Scientist ARCHITECT: Carrère & Hastings DATE: 1899-1903 STYLE: Beaux-Arts The First Church of Christ, Scientist, built in 1899-1903 at the northwest of Central Park West and 96th Street was designed in the finest tradition of Beaux-Arts classicism. Although the architects of his church designed a few churches, the Christian Science building is very much in keeping with its designs for other public buildings.

39-35 West 89th Street, ca.1915. This series of Renaissance Revival rowhouses was constructed in 1894-1895. The row, from nos.19-39, were designed by Gilbert Schellenger, who designed homes all over the city, including many in the proposed Bedford-Stuyvesant historic district.

First Church of Christ, Scientist, ca. 1990. The First Church of Christ, Scientist, was designed by Carrère & Hastings and built between 1899-1903. The firm’s imposing Beaux-Arts design fulfilled an intriguing commission: to create a grand ecclesiastical architecture for a relatively young religion. The design incorporates a large central auditorium, in addition to two upper stories of offices and areas for study. The building is notable for its large stained glass windows, especially those facing Central Park. In 2004, the church was sold to the California-based Crenshaw Christian Center. Ten years later, it was sold again, this time to a private developer. A planned adaptive redevelopment/condominium conversion project was later rejected, and in early 2018 the Children's Museum of Manhattan announced that it had acquired the building.

Apthorp Mansion, 1891. The Apthorp Farm was a large plot of land on what is now the Upper West Side of Manhattan (approximately 78th to 99th Streets, from Central Park to the Hudson River). Loyalist and merchant Charles Ward Apthorp purchased parcels and built a mansion in 1764 at what is now 90th Street and Columbus Avenue. It was considered one of the grandest pre-Revolutionary houses in Manhattan. The Hudson River-facing mansion was called "Elmwood" because of the large, mature elm trees that stood nearby. During the Revolutionary War the home was occupied by both sides at various points, a hard fact for the faithful British subject, Apthorp. In the mid 19th century the house and some of the surrounding land became "Elm Park," a beer garden, picnic area, and inn popular among German immigrants. It was also used as a parade ground, where in 1870 a clash between Irish Catholics and Irish Protestants resulted in eight deaths. The home was demolished in 1891, while the original acreage had largely been divided and sold off decades earlier. In 1908 a large apartment house was constructed on the full block between Broadway and West End Avenue and West 78th and West 79th streets. That plot of land had once been occupied by a different home built by Apthorp in 1759 (and sold to someone else less than ten years later). The 20th century apartment building was named for the original landowner.
