| Sales Force Tower |
Working on the Salesforce Tower in San
Francisco and the Wilshire Grand Center in Los Angeles, we have a newfound respect
for the advancements made over the last century in the construction of
skyscrapers. Developments in engineering techniques made it
easier to construct tall buildings as well as to live in them, and New York
City was at the center of some of the most progressive tower designs.
During the first decades of the
twentieth century, America experienced an upsurge in skyscraper construction as
the demand for more modern office space grew. This period saw the construction of such
iconic buildings as the Flatiron in 1902.
Located on Fifth Avenue in Manhattan, the steel-framed, 22-story
building is considered to be a revolutionary skyscraper. The wedge-shaped building is situated on the
triangular block of Fifth Avenue, Broadway and East 22nd Street, and
got its name from the resemblance to a “cast-iron clothes iron.” In 1989, it was designated a National
Historic Landmark.
Other outstanding buildings from that
era include the Singer Tower at Liberty Street and Broadway in Lower
Manhattan's Financial District. The
47-story headquarters of the Singer Manufacturing Company was completed in 1908
and stood 612-feet tall. The building
was demolished in 1968. The Metropolitan
Life Insurance Company Tower, built in the Renaissance Revival and Gothic
architectural styles, was 700-feet tall and opened in 1909.
The Woolworth Building is another prominent
building from the early twentieth century.
Furthermore, over a century after the start of its construction, the 792-foot
tall building is still one of the one-hundred tallest buildings in the U.S. and
one of the thirty tallest buildings in New York City. Opened in 1913, it was designated as a
National Historic Landmark in 1966.
