The document summarizes architectural styles from the 1920s-1930s, including Modernism, Expressionism, Bauhaus, International Style, and Art Deco. It discusses how World War I led to simplified forms in Europe and a new style combining simplicity and minimal ornamentation in the US. Key modernist architects like Le Corbusier, Walter Gropius, and Mies van der Rohe rejected historical styles in favor of reduced forms expressing structure and function. The Bauhaus school also emphasized functionality and influenced the later International Style of glass, steel, and concrete buildings. Expressionism used distorted forms to create emotional responses.

2. Socio economic conditions during 1920s
■ In North America, it is frequently referred to as the "Roaring Twenties" or the "Jazz Age“ because of the
economic boom following World War I.
■ This period of prosperity was the result of a paradigm shift in global affairs.
■ These shifts in the 1920s, occurred in part as the result of the conclusion of World War I and Spanish
flu.(1918)
■ The era saw the large-scale adoption of automobiles, telephones, motion pictures, radio and household
electricity, as well as unprecedented industrial growth, accelerated consumer demand and aspirations, and
significant changes in lifestyle and culture.
■ In some countries the 1920s saw the rise of radical political movements, especially in regions that were once
part of empires.
■ Communism spread as a consequence of the Russian Revolution in Russia which dismantled the Tsarist
autocracy and led to the rise of the Soviet Union.
■ But for the UK economy it was a period of depression, deflation and a steady decline in the UK’s former
economic pre-eminence.
■ After the post-war boom of 1919-20 ended, UK unemployment rose sharply to over 10%, and stayed high
until the Second World War.

3. SOCIETAL DYNAMICS DUE TO WORLD WAR I(1920s – 1930s)
Economical Aspects
•Economically, the war severely disrupted the European economies and allowed the United States to become the
world's leading creditor and industrial power. That is why, the architecture in Europe got shifted towards simple and
pure forms. And in America a new style was founded which is the combination of simpler forms with little
ornamentation.
Political Aspects
• The status of the aristocracy was diminished. The distribution of income shifted in favor of the poor.
Social Aspects
• Due to the downfall of aristocracy the focus got shifted on meeting the needs of the middle and working
classes.
Cultural Aspects
•After world war 1 there were global exchange of ideas and way of living that led the people got influenced by each
other.

4. CHANGES IN
ARCHITECTURE
AFTER WORLD
WAR I
After World War I, pioneering modernist architects sought to develop a completely new
style appropriate for a new post-war social and economic order, focused on meeting the
needs of the middle and working classes.
Rejected the architectural practice of the academic refinement of historical styles
The approach of the Modernist architects was to reduce buildings to pure forms.
The nineteen twenties brought a feeling of freedom and independence to millions of
Americans, especially young Americans who fought in the world war I. They come up with
new ideas of way of living.
Earlier modernism was only a national movement but after the world war it spreads
internationaly. This led to the establishment and rise of the extreme form of modernism
during early 1920s.

5. FACTORS THAT HELP
SHAPING MODERNISM
Technological advancement- In the period of the 1900, the world at the time was a bustling
place that was shaped new discoveries of the inventions and new technological advancement
that were thrust to the civilization.
Philosophical theoreticians changed the way that modern perceives the modern world. The
modernist were militant about distancing themselves from every traditional idea .
Economy -The science and the technology were the radical change means to the production
Growing tension and the social order
The diverse cultures in the world.

RISE OF MODERNISM
■ After the first World War, a prolonged struggle began between architects who favored the more traditional
styles of neo-classicism , and the modernists, led by Le Corbusier, Walter Gropius and Ludwig Mies van der
Rohe in Germany, who wanted only pure forms and the elimination of any decoration. The approach of the
Modernist architects was to reduce buildings to pure forms,

7. CHARACTERISTICS OF MODERN ARCHITECTURE
 Simplicity in form and absence of
intricate decorations
 Notion of Form follows function
 Visual Expression of structure
rather than hiding the structure
 Truth to materials
 Machine asthetics

8. BAUHAUS(1919-1933)
■ Founded by Walter Gropius in Weimar in 1919
■ One of the first colleges of design
■ Was an innovative training centre.
■ The school emerged out of late-19th-century
desires to reunite the applied arts and
manufacturing, and to reform education.
■ The German term Bauhaus—literally
"construction house"—was understood as
meaning "School of Building"
■ The design is a further development of an
idea that Gropius had previously realised with
the construction of the Fagus factory. In both
buildings a glass facade on the load-bearing
framework allows a view of the interior
workings

9. Bauhaus style
■ Great style of architecture for those who prefer minimalism
■ This style of architecture also holds true to the old saying “less
is more”.
■ Buildings constructed from the Bauhaus style are always cubic
in shape.
■ they features flat sides and flat rooftops.
■ The colours of the typical Bauhaus building are black, white,
grey.
■ The interiors of the building reflects a functional open floor
plan.
■ The Bauhaus had the intention of creating an 'International
Style' by using shapes and colors that were easily replicated,
and were unlikely to cause offence to other religions or
cultures.
Using geometric shapes and unusual angles can be
categorised as a Bauhaus replica

10. INTERNATIONAL STYLE
■ Developed in Europe and the United States in the 1920s and
’30s
■ Became the dominant tendency in Western
architecture during the middle decades of the 20th century.
■ The term International Style was first used in 1932
by Henry-Russell Hitchcock and Philip Johnson in an
architectural exhibition .
■ The International Style was thus formed under the dictates
that modern buildings’ form and appearance should
naturally grow out of and express the potentialities of their
materials and structural engineering.
■ Hitchcock and Johnson identified three principles: the
expression of volume rather than mass, the emphasis on
balance rather than preconceived symmetry, and the
expulsion of applied ornament.
■ The aim of Hitchcock and Johnson was to define a style that
would encapsulate this modern architecture.
Increasing dissatisfaction with the continued
use in stylistically eclectic buildings of a mix of
decorative elements from different
architectural periods
Civic structures that served a
rapidly industrializing society
The development of new building technologies
centring on the use of iron and steel, reinforced
concrete, and glass.

• Richard Neutra and Philip Johnson in the United States.

12. EXPRESSIONISM(1919-1933)
■ Expressionism was a modernist movement, initially in poetry and painting, originating in Germany at the
beginning of 20th century.
■ Typical trait is to present the world solely from a subjective perspective distorting it radially for emotional
effects in order to evoke moods or ideas.
■ Expressionism was developed as an Avant Garde style before the first world war.
■ The style extended to a wide range of the arts including expressionist architecture, painting, literature,
theatre, dance, film and music.
WHAT IS EXPRESSIONIST ARCHITECTURE?
■ Expressionist architecture was an architectural movement that developed in Europe during the first decades
of the 20th century in parallel with the expressionist visual and performing arts that especially developed and
dominated in Germany.
■ Expressionism transforms reality rather than seeking to imitate it.
■ The genesis of expressionism lies in art nouveau.
■ Art nouveau, a decorative art convention turned to bionic and geomorphic forms.

16. ART DECO STYLE (1910-1939)
ORIGIN
 Art Deco, sometimes referred to as Deco, is a style of
visual arts, architecture and design that first appeared in
France just before World War I.
 It took its name from Arts Décoratifs, from
an Exposition held in Paris in 1925.
 Art Deco had begun in France before World War I and
spread through Europe;
 In the 1920s and 1930s it became a highly popular style
in the United States, South America, India, China,
Australia and Japan.
 In Europe, Art Deco was particularly popular for
department stores and movie theaters.
 The style reached its peak in Europe at the International
Exhibition of Modern Decorative and Industrial Arts in
1925, which featured art deco pavilions.

17. INSPIRATIONS AND INFLUENCES
Influences form the past:
 The decorative motifs from the ancient
near eastern cultures of assyria.
 Egyptian elements such as stylize
blossom’s, scarabs and papyrus leaves and
exotic motifs
 Africansculpture
 Persian or Moorish details appear on few
art deco buildings

18. CHARACTERISTIC FEATURES:
■ It combined very expensive materials and exquisite
craftsmanship put into modernistic forms.
■ It had many features of modernism and it rejected traditional
historical models, such as the Beaux-Arts style and Neo-
classicism;
■ Ornamentation in the form of panels, cornices, parapets,
Window and door
■ Terra-cotta, colored glass, glass block, and various exposed
metals for ornamentation.
■ Materials include jade, linoleum, steel, plastics, chrome, and
Bakelite. Metal was a perfect representation of what Art Deco
strove to represent, which was strength and industrial might .
■ Notable architects of this movement were Raymond Hood,
William Van Allen(Chrysler building), Donald Deskey(Radio city
music hall),Victor Horta, Wirt C. Rowland, William F. Lamb,

20. FACTORS
LEADING TO
THE
EMERGENCE OF
ART DECO
The emergence was closely connected with the rise in status of decorative
artists.
Art Deco architecture represented scientific progress, and the consequent rise
of commerce, technology, and speed.
This, together with its image as a modern, opulent style, made Art Deco
designs especially suitable for the interiors of cinemas, ocean liners such as
the Queen Mary, and the architecture of train stations across the United
States.
It suffered a decline in popularity during the late 30s and early 40s, when it
began to be seen as too gaudy and ostentatious for wartime austerity, after
which it quickly fell out of fashion.

21. ■ In the late 1920s and early 1930s, an
exuberant American variant of Art Deco
appeared .
■ Immense development in building design and
engineering.
■ Combined modern materials and technology
(stainless steel, concrete, aluminum, chrome-
plated steel) with Art Deco geometry, stylized
zig-zags.
■ Rise of the industry led to the rise of
skyscrapers.
■ They were designed to show the prestige of
their builders through their height, their shape,
their color, and their dramatic illumination at
night.
■ In New York, Art Deco is exemplified in
its Skyscraper Architecture, including designs
for buildings like:

23. CONSTRUCTION
■ Development of steel, Reinforced Concrete, elevators and hand pumps made
possible the construction of skyscrapers.
■ The construction combined modern materials and technology like stainless steel
,concrete, Aluminium and Chrome-plated Steel with Art Deco geometry.
■ The development of structural steel and reinforced concrete allowed relatively small
columns to support large loads and exterior walls of buildings were no longer
needed for structural support.
■ A new construction technique called a curtain wall was developed .The idea was that
the exterior walls should be a covering to keep out the weather.

24. RESIDENTIAL ARCHITECTURE DURING 1920s
■ The First World War indirectly provided a new impetus, when the
poor physical health and condition of many urban recruits to
the army was noted with alarm.
■ This led to a campaign known as Homes fit for heroes to enable slum
clearance.
■ In 1919 the Government first required councils to provide housing
through the provision of subsidies, under (Housing Act 1919) which
came to be known as Council houses.
■ London County Council embraced these freedoms and planned
8 cottage estates in the peripheries of London
■ Slum clearance now moved from being a public health issue, to a
matter of town planning.
■ A popular style of housing that began in the previous decade and
carried over with improvements into the twenties was
the Bungalow, often referred to worldwide as the California
Bungalow.

25. OTHER ARCHITECTURAL MOVEMENTS:
DE STIJL
■ First conceived in 1917 and prevalent upto 1931 in the Netherlands, De Stijl was introduced as a total style centered
around the idea to fathom the purity of form and the reality of nature.
■ Having an awareness of a purified, universal form, De Stijl architecture was seminal for the development of what we
today know as Modern architecture.
■ Notable De Stijl architects were Gerrit Rietveld, J.J.P. Oud, Bart Van der Lack, Cornelis van Eesteren, Jan Wils,
and Robert van ‘t Hoff.
FRANK LLOYD WRIGHT MAYAN STYLE
■ Meanwhile, in the United States, Frank Lloyd Wright refused to associate himself with any architectural movements
considering his work to be entirely unique.
■ During the 1920s, he developed his “Mayan style”, houses decorated with textured blocks of cement.
■ He identified his architecture as “Usonian”, a combination of USA, “utopian” and “organic social order”.
