Few city neighborhoods in the West have the variety and quality of early 20th Century residential architecture to equal Portland’s historic Irvington Neighborhood. Portland’s population boomed in the years after 1900, spurred by the 1905 Lewis & Clark Centennial Exposition. With the west side of the Willamette River fully built up, the city expanded to the east side trolley car suburbs like Irvington in the years from 1900 through 1948 (when trolley car service was suspended).
Upper middle class Portlanders built substantial Irvington houses in the styles common to the period — Arts and Crafts, Craftsman, Colonial Revival, Prairie Style, Bungalow — many with an inventiveness and creative touch freed from East Coast architectural proprieties.
