Egan House, Northwest Regional style house in Capitol Hill, Seattle, United States.

Egan House is a Northwest Regional style house designed by Robert Reichert in 1958 for retired US Navy Rear Admiral Willard Egan. It stands within Seattle's St. Mark's Greenbelt and was designated a Seattle Landmark in 2010.

Robert Reichert designed this residence in 1958 for Admiral Willard Egan, with construction finishing in 1959. The building gained protected landmark status from the Seattle Landmarks Preservation Board in 2010.

The house reflects how modern architecture shaped residential living in Seattle during the 1950s. Its unusual triangular form was a statement for progressive design and continues to draw those interested in architectural innovation.

The house stands on a slope inside St. Mark's Greenbelt, so the triangular plan reads best from the street below rather than from above. Historic Seattle, which restored the building in 2003, put it up for sale in April 2024, so the interior is not open to visitors; the exterior is what can be seen.

The home underwent restoration in 2003 and demonstrates how Seattle has preserved modernistic structures from the postwar decade. The restoration work kept the original architectural vision intact, making it a rare surviving example of postwar modern residential design in the city.
