Prairie houses 
By 1901, Wright had completed about 50 projects, including many houses in Oak Park. As his son John Lloyd Wright wrote:  "William Eugene Drummond, Francis Barry Byrne, Walter Burley Griffin, Albert Chase McArthur, Marion Mahony, Isabel Roberts and George Willis were the draftsmen. Five men, two women. They wore flowing ties, and smocks suitable to the realm. The men wore their hair like Papa, all except Albert, he didn't have enough hair. They worshiped Papa! Papa liked them! I know that each one of them was then making valuable contributions to the pioneering of the modern American architecture for which my father gets the full glory, headaches and recognition today!"My Father: Frank Lloyd Wright, by John Lloyd Wright; 1992; page 35Between 1900 and 1901, Frank Lloyd Wright completed four houses which have since been identified as the onset of the "Prairie style". Two, the Hickox and Bradley Houses, were the last transitional step between Wright's early designs and the Prairie creations.Clayton, Marie (2002).  Meanwhile, the Thomas House and Willits House received recognition as the first mature examples of the new style.Sommer, Robin Langley (1997).  At the same time, Wright gave his new ideas for the American house widespread awareness through two publications in the Ladies' Home Journal. The articles were in response to an invitation from the president of Curtis Publishing Company, Edward Bok, as part of a project to improve modern house design. Bok also extended the offer to other architects, but Wright was the sole responder. "A Home in a Prairie Town" and "A Small House with Lots of Room in it" appeared respectively in the February and July 1901 issues of the journal. Although neither of the affordable house plans were ever constructed, Wright received increased requests for similar designs in following years.Clayton, Marie (2002). 

Wright's residential designs were known as "prairie houses" because the designs complemented the land around Chicago. These houses featured extended low buildings with shallow, sloping roofs, clean sky lines, suppressed chimneys, overhangs and terraces all using unfinished materials. The houses are credited with being the first examples of the "open plan". Windows whenever possible are long, and low, allowing a connection between the interior and nature, outside, that was new to western architecture and reflected the influence of Japanese architecture on Wright. The manipulation of interior space in residential and public buildings are hallmarks of his style.

Public buildings in the Prairie style include Unity Temple, the home of the Unitarian Universalist congregation in Oak Park. As a lifelong Unitarian and member of Unity Temple, Wright offered his services to the congregation after their church burned down in 1905. The community agreed to hire him and he worked on the building from 1905 to 1909. Wright later said that Unity Temple was the edifice in which he ceased to be an architect of structure, and became an architect of space. Many architects consider it the world's first modern building, because of its unique construction of only one material: reinforced concrete. This would become a hallmark of the modernists who followed Wright, such as Mies van der Rohe, and even some post-modernists, such as Frank Gehry.

Many examples of this work are in Buffalo, New York as a result of a friendship between Wright and Darwin D. Martin, an executive of the Larkin Soap Company. In 1902, the Larkin Company decided to build a new administration building. Wright came to Buffalo and designed not only the Larkin Administration Building (completed in 1904, demolished in 1950), but also homes for three of the company's executives including the Darwin D. Martin House in 1904, and later, their summer residence, the Graycliff Estate, also designed for Darwin D. Martin and his wife, Isabelle.

Other Wright houses considered to be masterpieces of the late Prairie Period (1907–2000) are the Frederick Robie House in Chicago and the Avery and Queene Coonley House in Riverside, Illinois. The Robie House, with its soaring, cantilevered roof lines, supported by a 110-foot-long (34 m) channel of steel, is the most dramatic. Its living and dining areas form virtually one uninterrupted space. This building had a profound influence on young European architects after World War I and is sometimes called the "cornerstone of modernism". However, Wright's work was not known to European architects until the publication of the Wasmuth Portfolio.
