Abbott Graves House, Prairie School residence in Kennebunkport, United States.

The Abbott Graves House at 86 Ocean Avenue is a two-story wood-frame house finished in white stucco, with a broad shallow-pitch hipped roof. A central section is flanked by projecting sections, with a single-story shed-roof porch between them, and single-story wings extend north and south. The symmetry is deliberately broken: one projecting section has three windows above two, the other two above three.

Built in 1905, the house served as the private residence of Abbott Fuller Graves and represents an early example of Prairie School design on the East Coast. Its listing on the National Register in 1980 marked official recognition of its architectural importance.

The building displays Frank Lloyd Wright's design approach through its strong horizontal lines and varied window patterns that seem to open toward the river. These features create a clear visual connection between the interior and the natural surroundings outside.

The house sits on the east side of Ocean Avenue, south of downtown Kennebunkport, with clear views toward the Kennebunk River. It remains visible from the public road, making it accessible for exterior viewing without entering private property.

Graves designed the house himself in 1905, after summering in Kennebunkport since 1891; he lived in it until his death in 1936. Its window layout is deliberately asymmetric: one projecting section has three windows above two, the other two above three.
