Robie House, Chicago (1909)

Robei House, Chicago (1909)
Frank Lloyd Wright

All the characteristics of the early Prairie houses were here: strong horizontal planes and masses, open interiors, bold cantilevers, and a strong attachment to the earth. Visually, this brick structure was a series of exciting planes, suggestive of a ship at sea. In its urban setting, it became one of the most celebrated residences in modern architecture.

Larkin Building, Buffalo (1904)

Larkin Building, Buffalo (1904)
Frank Lloyd Wright

The essential drama of the Larkin Building was a central, skylighted, four-story well. This soaring space was surrounded by office galleries that derived spatial unity from their outlook onto the central well. The structure and the largely unbroken exterior walls were constructed of flat bricks, and the staircase towers were strongly articulated as freestanding elements. Unfortunately, this landmark of modern design was demolished in 1950.

Flatiron Building, NY

Flatiron Building, New York (1902)
Daniel Burnham

Placed on a prominent, triangular site, this steel-framed structure owed much to the classical influence of the day. It has a well-defined base and a shaft and a Sullivanesque (Louis Sullivan+Romanesque) capital, which were all well composed in a single, powerful volume. The 20 or so stories rose majestically from the sharp corner site and established a model for later tall buildings.
