A large part of Chicago’s business district was
wiped out by fire in 1871, and its rebuilding saw the birth of the
skyscraper as we know it. High land values pushed office buildings upwards.
The elevator, pioneered by Otis and given electric power by von Siemens,
gave access to upper floors which could then generate high rentals. The
steel frame made it possible to build high without recourse to enormously
thick load-bearing walls of brick or stone. During the x88os and 189oS
Chicago architects gradually came to grips with these new realities and the
need to find an appropriate architectural expression for them. Louis
Sullivan’s Schlesinger & Meyer (later Carson, Pine, Scott and Company) store
of 1899 summed up these developments: its steel frame (which still had to be
sheathed in terracotta fireproofing) clearly expressed the grid of vertical
columns and horizontal beams framing openings considerably wider than they
were high, which were filled in with large windows. This new form of
expression flouted precedent and convention: it had always been assumed that
the wall area of a façade would exceed the window area, and window openings
were expected to have vertical rather than horizontal proportions.
Recognition of the rationality of the ‘Chicago solution’ to the problem of
the high building has been evident throughout the twentieth century.
Somewhat belatedly, Australian commercial buildings showed Chicagoan
influences most strongly during the period from World War Ito the
Depression. The Inter-War Chicagoesque style appears in buildings of widely
differing status, ranging from unpretentious brick warehouses to prestigious
office blocks and department stores which have some of the trappings of the
INTER-WAR COMMERCIAL PALAZZO style. The common factor is the horizontally
emphasised window opening and the frank expression of the fact that the
building has a steel skeleton frame. Rarely, however, did the designer give
equal emphasis to horizontal and vertical elements on a façade. More often
than not, horizontal spandrels beneath each set of windows are recessed
behind unbroken vertical pier-like elements which suggest giant classical
pilasters running through several storeys.
Examples
Westminster House, George Street, Sydney, NSW. Architect and date unknown. A
building recalling the Chicago skyscraper work of William Le Baron Jenney.
Sheffield House, Pitt Street, Sydney, NSW. Architect unknown, 1922. The
façade bays are so wide that they express a structural framework within.
Style
Definition
The "Chicago School of Architecture" was a proto-modernist style
which arose during the building boom after the Chicago Fire. The style is
a major step in the direction of simplified modern architecture, and
although it incorporates many features of historical styles the ornament
is subordinated to the overall structural scheme. The style encompasses
the first skyscrapers, and in many buildings the facade depicts nothing
more than the rectangular steel grid underneath.
Buildings in this style were built in
various cities, mostly in the Midwest but even in New York. Its influence
was very strong in industrial architecture, and many early factories and
warehouses fall into this category of design.
The two most prolific and important firms
in the early development of the Chicago School were Holabird & Roche
and Burnham and Root. The firm of Adler & Sullivan designed many of
this style's most refined works, with intricate organic decorations in a
style related to Art Nouveau.
