Timeline Of Architectural Styles

3. Corporate Style Greek Revival
this style was based upon the new technologies of construction, which were glass, steel, and reinforced concrete. (Very Similar to International Style architecture)
the style was looked as the expression of nationalism and civic virtue, and freedom given by its lax detail. It had a Greek based furniture and interior design.

4. Gothic Revival Italianate
this style drew features from the original gothic style, such as decorative patterns, finials, scallops (which are semi-circular surfaces carved into a building for design), long windows, hood mouldings and label stops, which were used to throw off rainwater.
this style primarily had sloping roofs, overhanging edges on the roofs, decorative brackets, tall, round windows, and were built out of brick, stone or stucco.

5. Richardsonian Romanesque Late/Post Modern
this style was similar to medieval styles as buildings were made mostly of stone. It used proportions and materials to increase visual weight.
this style’s buildings had their own aesthetic: their styles and form were different and clashed with each other, they had different viewing styles, and had a large amount of space. They also took ideas from styles before the modern architectural style.

6. Prairie School Art Deco
this style’s buildings looked very wide, due to their horizontality. It seemed more organic as it was reminiscent of the flat, open expanses of the Mid-West of the United States and the U.S. in its early, undeveloped days.
this style combined modern architecture with rich materials and craftsmanship. It represented luxury, glamour, and technological progress. It used materials such as ivory, ebony, chrome plating, stainless steel, and plastic.

7. International Style Brutalism
this style’s major characteristics are: buildings that are rectilinear, light, stretched surfaces that are devoid of decoration, open spaces, and cantilever construction.
buildings of this style were very large and were fortress-like. They were constructed with the concrete parts exposed and a combination of concrete and brickwork. The buildings were built with a high emphasis on elevation. They were usually school buildings, high-rise houses, government buildings, and shopping centers.

8. Chicago School
The Chicago school of architecture first started in the early 20th century. Its special aesthetic influenced European Modernism. Afterwards, in the 1940s and 1970s the Second Chicago School emerged, developing new structural forms and technologies. The buildings of the Chicago school use steel frames with masonry cladding to allow large windows. The lowest floors of Chicago school skyscrapers function as a base, having little decoration and being wider, the middle floors of the skyscraper are thinner and function as a shaft, and the top floors are the main emphasis, being decorated and ornamental.  The architectural style created the "Chicago window", which is a main window with two windows on its sides. These could be projected outwards, forming bay windows.
