One Los Angeles Frank Lloyd Wright house renovated, another falling down a hill. “If only it were that simple. It turns out that Ennis-Brown, once you get past the gaping holes on its lower flank, looks surprisingly good, particularly its stunning split-level living and dining room space — though that shouldn’t dissuade you from making a donation to help shore it up. And at the Barnsdall House, the handsome renovations can’t disguise the dispiriting mess the city has made, and continues to make, of its site or that behind its low walls is one of Wright’s least appealing domestic interiors.”
