This presentation gives an idea about the works, ideology of Louis Sullivan

2. INTRODUCTION
 Louis H. Sullivan (1856-1924)
was one of the most influential
architects to come out of the
Chicago School of architecture in
the late 1800s.
 He is often called the father of
the skyscraper or the prophet
of modern architecture .
 Louis Sullivan’s architecture is a
mixture of
1. plain geometry
2. undisguised massing
punctuated with elaborate
pockets of ornamentation in
stone, wood and terra cotta.

3. For follow fu ctio -louis

 Form follows function -
The principle is that the
shape of a building or
object should be primarily
based upon its intended
function or purpose.
 Functionalism of the
building was the main
important criteria for louis
sullivan in their building.
 He takes simple geometric
forms which makes it
distinctive style of
ornament that embraced
natural forms.

5. ORGANIC SYMBOLS WERE USED
FOR CREATING ORNAMENTATION

6. STEEL STUCTURES
 The mass production of steel was the
main driving force behind the ability to
build skyscrapers during the mid-
1880s.
 The development of cheap, versatile
steel in the second half of the 19th
century changed rules.
 The taller the building, the more strain
this placed on the lower sections of the
building; since there were clear
engineering limits to the weight such
"load-bearing" walls could sustain,
large designs meant massively thick
walls on the ground floors, and
definite limits on the building's height.
 A much more urbanized society was
forming and the society called out for
new, larger buildings.

7. SEMI-CIRCULAR ARCH
 Another signature
element of Sullivan's
work is the massive,
semi-circular arch.
 Sullivan employed such
arches throughout his
career—in shaping
entrances, in framing
windows, or as interior
design.

9. PLANS
The building is essentially a U-shaped plan stacked upon a rectangular solid. The interstitial
spaces between wings of the U create opportunities to introduce skylights to the lobby
below, and to cover the ceilings with stained glass. The plan contained a single vertical
circulation core with four elevators, a mail slot, and staircase. No fire-stair was provided or
necessary. The internal portion of the U faces south so as to collect light for the interior
recesses of the building- light being a necessary commodity to attract good tenants

10. Sections and elevation

11.  The structure was built
entirely of steel
 Combines masonry with
terra cotta
 Ornaments :most
defining characteristics
 used strong vertical lines
to emphasize their
verticality

14.  The Auditorium
Building in Chicago is one
of the best-known designs
of louis Sullivan.

that all seats would have
good views and acoustics

15. Sectional view of the building

16. features
 The building was equipped with the
first central air conditioning system &
 the theater was the first to be entirely lit
by incandescent light bulbs
 The theatre, created to hold up to 4,200
audience members.
 The raft foundation distributes the
weight of the massive outer walls over a
large area
 Ceiling is constructed in such a way that it
doesn’t reflect large amount of incident
sound energy; but absorbs
