creates a grid pattern, with some

12

13. ORIGIN OF PRAIRIE ARCHITECTURAL STYLE
• The Prairie style emerged in semi-rural
village on the Western edges of Chicago
in the early 1890s from the work of a
group of young architects, including Frank
Lloyd Wright.
• The Prairie School developed in
symphony with the ideals and design
aesthetics of the Arts and Crafts
Movement begun in the late 19th century
in England by John Ruskin, William
Morris, and others.

14. ORIGIN OF PRAIRIE ARCHITECTURAL STYLE
• The title Prairie is due to the dominant horizontality of most Prairie style buildings,
which resembles the wide, flat, treeless expanses of the mid-Western US.
18/4/2022 Pitch deck title 14

15. ORIGIN OF PRAIRIE ARCHITECTURAL STYLE
• The Prairie School was an attempt
at developing an indigenous
North American style of
architecture that did not share
design elements and aesthetic
vocabulary with earlier styles of
European classical architecture.
• The primary ideology of which was
that a building’s form should
grow out of its particular
environment to exist in harmony
with nature.

16. CHARACTERISTICS
• Characterized by dramatic
horizontal lines and masses,
Prairie buildings evoke the
expansive Midwestern
landscape.
• The buildings reflect an all-
encompassing philosophy that
Wright termed “Organic
Architecture.”
• No tall buildings
• Residences and banks

18. ORGANIC ARCHITECTURE
• Organic architecture is a
philosophy of architecture
which promotes harmony
between human habitation and
the natural world.
• This is achieved through design
approaches that aim to be
sympathetic and well-
integrated with a site, so
buildings, furnishings, and
surroundings become part of a
unified, interrelated
composition.
