Statement of Significance (as of designation - April 4, 2007):
The Aline Barnsdall Complex (or Hollyhock House) and associated buildings and structures are nationally significant as part of Frank Lloyd Wright’s first commission in Los Angeles, California. The project’s centerpiece was oil heiress Aline Barnsdall’s residence, largely built between 1919 and 1921. The visual character of the Hollyhock House expressed Wright’s transition away from the dwellings of Wright’s "First Mature" or "Oak Park" period (1900-1912), yet it was the building’s more understated elements that had impact on later residential design. Its free-flowing living areas and integrated accommodation between indoor and outdoor living became elemental features of Post-war houses.
