Handwritten annotations on the form give a construction date of 1923; the architect is identified as Frank Lloyd Wright.","why_significant":"The house is one of four California textile block houses by Frank Lloyd Wright, a period in his work when surfaces were heavily ornamented. It uses Maya-inspired motifs and inward-sloping walls, and is described as the most formidable of the series. Its plan, with a long gallery into which rooms flow, is noted as especially interesting.","narrative":"Perched on a hill at 2607 Glendower Avenue in Los Angeles, this two-level house looks like a fortress, with heavy retaining walls and terraces around a dense mass of 16-inch concrete blocks cast in an ornamental pattern. Steel gates and a bronze grille on the teak front door carry Maya motifs, which also appear in the textured block, a stair grille and a bronze plate over the dining room fireplace. A long gallery and a swimming terrace connect the living spaces. It was designed by Frank Lloyd Wright and is one of four California textile block houses, alongside the Millard, Freeman and Storer houses. The nomination presents these houses as a distinctive phase in his career, when he ornamented surfaces heavily and treated common concrete block as a noble material suited to the semi-arid climate. The inward-sloping walls borrow a structural practice from the Maya. Despite later alterations, the house largely follows its original plan.","period_of_significance":"20th Century","architect_builder":"Frank Lloyd Wright","architectural_style":null,"criteria":[],"status_note":"Condition listed as good and altered; many small changes and unskillful repairs, and the south terrace on the second level was roofed over.
